in an uncertain world, ‘green relief’ offers respite, healing and beauty

Have you ever sat with a cup of tea at the end of a weeding session, with a feeling close to happiness? Or returned from the local garden centre with a bag of potting mix and some plants – and soon the sight of your newly planted herbs or flowers makes your heart feel inexplicably lighter?

Perhaps you’re in hospital recovering from surgery, as I was only a little time ago. I regained consciousness in an advanced recovery unit, a dimly lit space with no windows where everything felt slightly surreal and too intense.

I was receiving the best possible care, yet I had a desperate sense of having been cut loose from my life, and even from my body, as it was monitored and medicated throughout the night. Who knows where things might go from here, I thought. Yet I almost didn’t care.

In the morning, I was wheeled away to a room on an upper floor. It was a space flooded with natural light and with a view of a wintry, cloudy sky and distant treetops.

When a friend arrived with a posy of flowers, I found myself smiling for the first time since leaving home. As well as the pleasure of her company, there was a surge of delight at the presence of flowers. Their soft colours soothed something in me that had been clutched tight in fear since my first glimpse of the stark, frankly terrifying operating theatre.

A history of healing

Perhaps now, more than ever, we could all use some green relief, as we deal with a world that seems to only grow more anxiety-inducing and uncertain.

In May, Australians will vote in what has been called “the cost-of-living election”. Housing prices (and homelessness) have soared, too, with one study putting the rise in housing value between March 2020 and February 2024 at 32.5%.

Elsewhere, war rages in Ukraine, Gaza, and other countries, and the world order is wobbling in the wake of the US elections – particularly this week, when Donald Trump’s tariffs sparked a stock market crash not seen since COVID (until he changed his mind yesterday and it recovered) and led to predictions of a recession.

What evidence is there that the natural world can have a healing effect?

In most cultures throughout history, medicine and botany have been closely entwined, and gardens have been associated with healing the body, mind, and spirit. From around the 4th century BCE, Greece had healing centres known as “asclepieia”, after the god of medicine, Asclepius.

In medieval Europe, monasteries kept medicinal gardens. In England, hospitals and asylums were set within landscaped grounds in the belief the tranquillity of the setting played an important role in lifting patients’ mood. Both male and female inmates of 19th-century asylums often worked in the gardens, in what was seen as a healing process administered by the place itself.

Inevitably, the creep of urbanisation saw the garden landscapes of many such institutions greatly reduced, yet the health benefits to patients of connecting with nature remains undiminished.

Flowers and healing

An explanation for the uplifting effect of those flowers in my hospital room may be found in numerous studies that have shown, post-surgery, patients in rooms with plants and flowers have shorter recovery times, require fewer analgesics, and experience lower levels of anxiety. Partly, it is a response to beauty.

As psychiatrist Sue Stuart-Smith writes in The Well Gardened Mind, the human response to beauty involves brain pathways “associated with our dopamine, serotonin, and endogenous opioid systems and damp down our fear and stress responses”. She continues: “Beauty calms and revitalises us at the same time.” We humans have an affinity for patterns and order, she writes. “The simple geometrics we find in nature are perhaps most concentrated and compelling in the beauty of a flower’s form.”

There has been a trend towards banning flowers from hospital wards, on health grounds. Reasons include a suspicion bacteria lurk in the flower water, as well as safety concerns around patients or nursing staff knocking over vases during night shifts.

Florence Nightingale, in her Notes on Nursing, commented on the beneficial effects of flowers on her patients. She added that they recovered more quickly if they could spend time outside, or at least had a room with adequate natural light. “It is a curious thing to observe how almost all patients lie with their faces turned to the light, exactly as plants always make their way towards the light.” Even if lying on a particular side caused pain, patients still preferred it, Nightingale noted – because “it is the side towards the window”.

Our compulsion to turn towards the natural world is known as “biophilia”. The term was first coined in the 1960s, by German–American social psychologist and psychoanalyst, Erich Fromm. He described it as “the passionate love of life and all that is alive”, speculating that our separation from nature brings about a level of unrecognised distress.

In the 1980s, biologist and ecologist Edward O. Wilson, in his book Biophilia, asserted that all humans share an affinity with the natural world. “The urge to affiliate with other forms of life is to some degree innate,” he wrote.

In hospital, as my body began its tentative recovery from the shock of surgery, I remembered a line popularly attributed to the French Impressionist painter, Claude Monet: “What I need most are flowers, always, and always.” Through his paintings, notably his studies of waterlilies, and the garden he established at Giverny, which welcomes visitors to the present day, Monet’s flowers continue to calm and revive us with their transcendent beauty.

Perhaps the simplest way to forge a connection with nature lies in our own suburban gardens, if we are lucky enough to have them. Aside from the pleasure of creating pleasing spaces, contact with the soil bacteria Mycobacterium vaccae has been shown to trigger the release of serotonin in the brain. Serotonin, a natural antidepressant, strengthens the immune system. An added bonus is that when we harvest edible plants, our brain releases dopamine, flushing our systems with a gentle rush of satisfaction and pleasure.

Regular doses of serotonin and dopamine were never more needed than during the pandemic, when lockdowns unleashed a sudden fervour for gardening.

In her book The Garden Against Time, Olivia Laing writes that “over the course of 2020, three million people in Britain began to garden for the first time, over half of them under forty-five”. And it wasn’t just in Britain, where garden centres ran out of plants and compost as people set to work transforming the spaces where they were confined.

Australia experienced a similar surge in interest, with the ABC reporting sales of herb and vegetable plants shot up 27%, joining toilet paper and pasta on the list of panic buys. In the United States, Laing writes, 18.3 million people started gardening, “many of them millennials”. American seed company W. Atlee Burpee “reported more sales in the first March of lockdown than at any other time in its 144-year history”.

Laing writes:

crouched on the threshold of unimaginable disaster, death toll soaring, no cure in sight – it was reassuring to see the evidence of time proceeding as it was meant to, seeds unfurling, buds breaking, daffodils pushing through the soil; a covenant of how the world should be and might again.

It is precisely this “evidence of time proceeding as it was meant to” that has the power to hold humans calmly in place. We may imagine we want more than this from life; despising dullness, we think we crave excitement and change. But given the option, few would choose to wake to an Orwellian “bright cold day in April” to find “the clocks were striking thirteen”, which is how it felt during those nightmarish early days of the COVID-19 crisis.

Life on earth does still feel somewhat bright and cold, its future somewhat bleak; it is as if Orwell’s dystopian vision is at last catching up with us.

Who would believe an activity so apparently humble as gardening could come to the rescue of millions of stressed and fearful people? Yet gardeners seem to know this instinctively.

Tending ourselves

In the book In Kiltumper: a Year in an Irish Garden, co-written with her husband, Niall Williams, Irish writer and gardener Christine Breen describes the ordeal of undergoing cancer treatment through the Irish healthcare system. Following an oncology appointment in Galway, the couple drives home towards west Clare, or as Christine puts it: “back to the garden, where there is safety”.

Christine’s husband Niall confirms that, although the medical community might dismiss the healing power of working in a garden as “airey-fairy”, in Christine’s case, even while weak from chemotherapy, “going about the flower beds, trying to do exactly the same work she had always done” meant continuity.

It represented “carrying on living, because that is one of the prime lessons any garden teaches you: the garden grows on”. He speculates that after many years together, garden and gardener become one: “when we tend it, we tend some part of ourselves”.

If we know this, we too often forget. Consequently, garden centres rarely top the list of most desirable destinations, and gardening has been traditionally represented as fussy and domestic. Weeding and mowing are seen as chores that, if possible, are to be avoided.

In her book Why Women Grow, Alice Vincent writes that gardening has “so many associations, of neatness and nicety; a prissiness that feels deeply removed […] from the sex and death and life on show in every growing thing.” She writes: “When we garden, we change how a small part of the world works.”

Doubtless, it was this sense of being able to change one’s world, of seizing control, that appealed to so many of us during the pandemic. And if we got our hands into the soil, we were rewarded with much-needed infusions of serotonin.

In literature, too, people suffering physically or mentally, or both, have often sought refuge or found solace in a garden.

For many readers, their first encounter with the transformative nature of gardening was Frances Hodgson Burnett’s classic children’s book, The Secret Garden. In it, a spoilt yet neglected child, Mary Lennox, is orphaned in India when her parents and their servants succumb to cholera. She is bundled off to Yorkshire, England, to a daunting atmosphere of secrecy and neglect at Misselthwaite Manor, into the care of an uncle she has never met. There, Mary soon discovers the key to a garden that has been locked for years following her aunt’s death.

In her efforts to restore life to the neglected garden, Mary herself is restored, gradually shedding the lonely, helpless persona of her Indian childhood. When she discovers the manor’s other tightly held secret – her sickly, bedridden cousin, Colin – Mary manages to get him, too, out of the house and into the garden. The outcome is healing for the children, and eventually for Mary’s grieving uncle.

Green prescriptions

For a real-life example of green relief, in The Well Gardened Mind, Sue Stuart-Smith describes how her grandfather – a submariner in the first world war – was taken prisoner during the Gallipoli campaign. After a series of brutal labour camps in Turkey, the last of them in a cement factory, he eventually escaped.

But after the long journey home he was so severely malnourished he was given only a few months to live. Crucial to regaining his health was the devoted nursing by his fiancée, followed by a year-long horticultural course set up to rehabilitate ex-servicemen.

A psychiatrist as well as a gardener, Stuart-Smith writes of the therapeutic effects of working with our hands in a protected space. She describes how gardening allows our inner and outer worlds “to coexist free from the pressures of everyday life”.

Gardens, she writes, are an “in-between space which can be a meeting place for our innermost, dream-infused selves and the real physical world”. In a garden, we are able to hear and process our own, sometimes turbulent, thoughts.

In 1986, after being diagnosed HIV positive, the English artist and filmmaker Derek Jarman retreated to the Kent coast near the nuclear power station at Dungeness. In The Garden Against Time, Olivia Laing writes that at Prospect Cottage, Jarman

began with stones, not plants: the grey flints he called dragon’s teeth, revealed by the tide on morning walks.

Gradually he established a garden in the inhospitable soil, seeing it as “a therapy and a pharmacopoeia” – and “a place of total absorption”.

It was this capacity to slow or stop time, as much as its wild and sportive beauty, that made it such a paradise-haunted place.

The pandemic spread waves of turbulence across the globe. In April 2021, as part of its post-COVID recovery plan, the government of the United Kingdom launched a two-year green social prescription pilot.

Project-managed by the National Health Service, the program worked across seven test sites: areas disproportionately affected by the pandemic. These included people living in deprived areas and people with mental health conditions, many of them from ethnic minority communities.

Over the course of the two-year program, more than 8,500 people were referred to a green social prescribing activity. Green networks were established in all seven test sites. Findings showed positive improvements in mental health and wellbeing – and green social prescribing is ongoing, proof of the program’s lasting impact.

In recent times, doctors in some countries are writing green prescriptions, rather than scripts for medication. And not just for mental health problems, but for physical conditions such as high blood pressure, diabetes and lung diseases.

In the late 1990s, New Zealand became one of the first countries where GPs used green prescriptions to encourage patients to increase their levels of physical activity. Japanese clinicians have been advocating “shinrin-yoku”, or forest bathing for decades. In Finland, with its long dark winters, five hours a month is regarded as a “minimum dose” of contact with nature.

Aside from the physical benefits, time spent in a garden can provide a mood boost for those of us who feel oppressed by calendars, and by clock time’s relentless march. In her 2018 memoir Life in the Garden, Penelope Lively writes:

To garden is to elide past, present and future; it is a defiance of time. You garden today for tomorrow, the garden mutates from season to season, always the same but always different.

Perhaps no group of people stands in greater need of time-defiance than those of us entering the final decades of our lives. Time is short, and we know it. But as now 92-year-old Lively wrote seven years ago: “A garden is never just now; it suggests yesterday and tomorrow; it does not allow time its steady progress.”

A garden is a ‘defiance of time’. Pexels

Gardening as defiance

My mother pottered in her garden until she was in her early 90s, pruning roses, pulling weeds, planting annuals and throwing down fertiliser. She’d wrestle her walker across the lawn to perch on its seat while she did the watering, before retreating to an armchair in the back room of her house, from where she could admire her achievements.

Gardening in extreme old age was, for her, an act of defiance – against time, and against her children, who nagged about the possibility of a fall and insisted she wear an emergency call button. It was a defiance, too, of the common view that old people should relinquish their homes with gardens and move into something more manageable.

On the face of it, not having a garden to maintain in old age makes perfect sense, but it may come at the expense of our human impulse to seek connection with living things, specifically those in the natural world. So ingrained is our instinct to connect with nature, it appears to survive even when other systems and connections have broken down.

A friend whose Alzheimer’s-afflicted husband is in residential care reports he is constantly finding odd containers, filling them with soil, and planting cuttings gathered from the care home’s garden. He crams them onto his windowsill, even planting in teacups when there is nothing else to hand.

Accustomed to gardening throughout his adult life, his impulse to work with living things persists in defiance of dementia. My friend reflects her mother used to do the same, only she would take pieces from the home’s fake indoor plants, then complain bitterly when they did not grow.

In the care facility my friend visits daily, women pick flowers in the grounds to decorate their walkers, and when there are no flowers they’ll use pictures of flowers cut from magazines. Cutting out paper flowers seems like the action of someone whose garden has been lost, but who still feels a powerful desire to connect with beauty and the natural world.

Imagined gardens

The theories of 20th-century historian Theodore Roszak, in his book The Voice of The Earth, founded the ecopsychology movement.

He believed “humans connect with nature through the ecological unconscious, which is the core of human identity”. Human nature, he wrote, is “densely embedded in the world we share with animal, vegetable, mineral”. He believed reconnecting with nature helps people become more aware of their connection to all living things.

So what are we to do if the garden has been lost?

The French writer Colette, whose books were full of botanical detail, did not cease gardening even when age and arthritis kept her bedridden. Rather than physical gardens, Colette roamed imagined gardens.

There is nothing so terrible about not having a garden any more. The worrying thing would be if the future garden, whose reality is of no importance, were beyond my grasp. But it is not.

Colette planned her “tomorrow garden”, specifying pansies “with wide faces, beards, and moustaches – that look like Henry VIII”. Nothing is too difficult for the imaginative gardener. “An arbour? Naturally I shall have an arbour. I’m not down to my last arbour yet.”

Imagining a garden may seem fanciful. Yet it is less so if considered in the context of embodied semantics – a process where brain connectivity during a thought-about action mirrors the connectivity that occurs during the actual action. (For example, thinking about running or swimming can trigger some of the same neural connections as the physical actions.)

It’s been shown that habitual negativity rewires the brain. Ultimately, it damages it by shrinking the hippocampus: one of the main areas destroyed by Alzheimer’s disease.

But gardens, with their earth-centred sense of time and season, are optimistic places. Watching things grow, deadheading spent flowers and saving seed for the return of spring, are just some of the forward-looking aspects of gardening and perhaps it works as well if the plants and flowers are imagined.

It is logical to go further and ask whether a positive habit, such as imagining a garden, has the potential to help rewire one’s brain in a good way. Imagined gardening is really a form of self-guided imagery, a practice with many applications in the treatment of pain, stress, anxiety and depression.

As we age, ideally we would find ways of getting our hands into the healing soil. Suggestions for gardening in old age, and extreme old age, include introducing raised beds to reduce bending, or working with potted plants.

A friend in her late 70s, with an enviable garden, swears by her Garden Group. Around a dozen friends come together for working bees in each other’s gardens. “You can get a huge amount done in an hour-and-a-half,” she says. Afterwards, they share morning tea – so it is a social as well as practical endeavour. My own best tip is to garden little and often. Committing to half an hour a day, or even 15 minutes, adds up nicely over the course of a week.

American poet May Sarton wrote of gardening as “an instrument of grace”. She regarded the natural world as the great teacher. From the Benedictine Monastery of Saint Paul de Mausole at Saint-Remy-de-Provence, Vincent Van Gogh wrote to his mother: “But for one’s health, as you say, it is very necessary to work in the garden and see the flowers growing.”

Like Monet, Van Gogh needed flowers. We all do. It’s just that many of us forget this during the push and pull of daily life. And in forgetting, we lose touch with our biophilic natures.The Conversation

Some ancient Romans got to retire with a pension at 42, but retirement’s changed a bit over the centuries

Over the ages, there have been broadly three reasons why people have retired.

Some are forced to by poor health – theirs or someone they care for. Others have alternative income sources, meaning they don’t rely on a regular pay cheque. And some are made to retire by an employer who wants to overhaul staffing.

But where did the idea of retirement come from? And how was it handled in ancient times?

Origins of support

Retirement support – which these days comes in the form of superannuation or a government pension – dates back to ancient history in various forms.

Some forms of retirement support were funded by local taxes or tithes, others by donations. Some systems were corrupt and the coverage was patchy.

Records are not readily available from other cultures, but we know a little about ancient Rome and English history since then.

Emperor Augustus, who ruled after Julius Caesar died, set up a scheme for Roman soldiers more than 2,000 years ago. The scheme aimed to ensure they retired while still strong and healthy, and would be less likely to cause trouble.

The scheme paid a decent amount for soldiers after 25 years of service, so retirement age could be as young as 42.

Pensions for older people in need also have ancient origins. The New Testament Bible records the churches had schemes for needy widows right from the beginning.

In the early Middle Ages, monasteries often provided for the needy, but Henry VIII famously closed them and took their assets. A fair share of their assets ended up with high government officials after the king’s takeover.

Industry funds can also be seen to date back at least to the Middle Ages, where the trade guilds provided for members and their families who fell on hard times.

Retail funds mainly began as mutual life insurance companies that began more than 200 years ago.

In the 18th century, the East India Company began offering pensions to retirees. Oil on canvas by Philip Le Couteur, Image number: 12577, National Army Museum.

In the 18th century, the East India Company and the Bank of England began offering pensions. These were at first discretionary based on need and loyalty, but later covered all employees. This idea then spread to other larger companies such railways and banks.

As modern states developed the capacity to collect income taxes, it became feasible to provide comprehensive retirement benefits funded by central government.

Beginning with Germany in 1889, developed countries began introducing universal national age pension arrangements.

Unfortunately, a number of countries, such as Papua New Guinea, still do not have the capacity to provide a universal safety net to cover older people.

Retirement in Australia

Three Australian states began schemes in 1900, and the federal government provided a universal (but means tested) scheme from 1909.

Most Australian retirees seem to enjoy a favourable standard of living. The Grattan Institute finds that the poorest 30% are, in fact, better off in retirement.

Massive house price and rental inflation in the last 30 years, however, has gutted the living standards of those who don’t own their own homes. This gap in the safety net needs to be addressed.

Retirement ages

The Roman army model persists in some countries to this day: retirement from the US military is available after 20 years of service.

Retirement this early is obviously very expensive. The church scheme mentioned in the New Testament had a minimum age of 60, which is still the normal retirement age in many countries.

The OECD reports the average age of retirement in their 38 member countries is just under 64 for women, and just over 64 for men.

Australians now qualify for the age pension at 67, which is slightly older than average.

Retirement ages are, however, rising to allow for “population ageing”, a longer life expectancy and lower birth rates. Life expectancy at retirement age is the important number when calculating the cost of pensions.

In ancient Rome it was about seven years and was about the same in Sweden in the middle of the 18th century.

In Australia, the life expectancy of a 65 year old woman has risen from 12 years in 1895 to 23 years on average.

Earnings-related pensions

The 1889 German scheme paid a minimum pension, plus an earnings-related component. Workers had a book for stamps for each week’s earnings.

The Australian age pension has always just paid a minimum “liveable” amount. This has been subject to different means tests over time, but retirees have been able to supplement it with their own savings.

Until 1987, only 40% of Australian employees were covered by employer sponsored schemes. Then in 1992, the Superannuation Guarantee Scheme was introduced. Under this, employers were required to contribute 3% into all exployees’ super.

The standard rate will rise to 12% in July next year.

The future

A growing ageing population will mean the Australian government and superannuation industry will need to adjust current support systems.

Over the next decade, about 2.5 million Australians will move from accumulation (where you’re building up your super) to join the 1.6 million already receiving super benefits.

We can expect more people to be living into their nineties and needing pensions for life.

One government priority is to make lifetime pensions as much part of the Australian system as they are in the rest of the world

And after 30 years of growing complexity in the rules covering superannuation, regulators are counting the cost, and planning some simplification.

Most Single Americans Look for Partners With These Career Values and Passions: New Dating Poll - Good News Network


A survey of 2,000 single Americans revealed that 56% of respondents agreed it’s important that their partners have the same career values that they do.

In terms of ambition, 44% would prefer someone whose career ambitions were the same as their own, while 34% are looking for someone who is even more ambitious.

Regarding salary, 39% of all respondents—which were equally divided between men and women—said they would prefer to be an equal “breadwinner” with their partners. Unsurprisingly, this was much more common for women, with 45% of females preferring salaries to be equal, compared to 33% of men.

Conducted by Talker Research on behalf of the dating app The League, the survey also looked at the most desirable careers for 2025.

29% of men and women agreed that those in the health care field make the best partners, while careers in education ranked as the second most attractive for the men surveyed (28%).

21% of women are interested in dating an entrepreneur, 19% were interested in an educator, while finance guys and artists were desirable for 18%.

Also ranking in the top most dateable jobs for both genders are lawyers (24%), scientists (16%), and careers in tech, like web or software developers (14%).

The poll also explored the ideal time to have “the career conversation” with potential partners. Nearly a quarter of respondents (22%) said that, ideally, they’ll have a conversation about goals and aspirations before going on a first date—but most will bring up the conversation by the end of their first date.

“Transparency is more attractive than ever,” said Rachel DeAlto, a dating expert at The League. “While there may be no perfect time to talk about careers and ambitions, bringing it up in conversation sooner than later in the dating process allows singles to determine if they share similar values and life goals from the start.”

Despite many respondents being eager to speak with potential partners about their career, that doesn’t mean single Americans are “all work and no play.” 40% of singles surveyed want their potential partners to have a passion for what they’re doing but also prioritize a work/life balance.

Gabriella Clare Marino

Additionally, over one in five respondents are looking for partners who have a desire to leave a positive impact on society or other people.

64% are willing to date someone in graduate school, further demonstrating the appeal of having drive and goals, no matter where your career is at the moment.

“When partners share similar aspirations and value the same things in life, they’re better equipped to support and understand each other. The key is to stay open to finding that alignment,” said DeAlto.

On the flip side, constant burn-out (32%), long overtime hours (29%) and switching jobs every year (25%) are some of the top career “red flags.” Interestingly, being an “influencer” was also a “red flag” for more than one in five respondents (22%).

WHAT CAREER VALUES ARE IMPORTANT IN A POTENTIAL NEW PARTNER?
  • Passion for what they’re doing — 40%
  • Prioritizing work/personal life balance — 34%
  • Understanding that there is always more to learn/ways to improve — 28%
  • Ability to work well with others and build relationships with colleagues — 25%
  • Desire to leave a positive impact on society or other people — 21%
  • Competitiveness or wanting to be successful — 19%
  • Desire to leave a positive impact on the environment — 15%
  • Desire to be a good manager or leader — 15%
  • Commitment to pushing the boundaries and paving new roads — 15%, Most Single Americans Look for Partners With These Career Values and Passions: New Dating Poll - Good News Network

Dealing with love, romance and rejection on Valentine’s Day

Playing with the affections of the heart can be tricky on Valentine’s Day. Flickr/tanakawho , CC BY-NC Lisa A Williams, UNSW Sydney

Take care lovers, wherever you are, as Valentine’s Day is soon upon us. Whether you’re in a relationship or want to be in a relationship, research over a number of years shows that February 14 can be a day of broken hearts and broken wallets.

A study by US psychologists in 2004 found that relationship breakups were 27% to 40% higher around Valentine’s Day than at other times of the year. Fortunately, this bleak trend was only found amongst couples on a downward trajectory who weren’t the happiest to begin with.

For stable or improving couples, Valentine’s Day thankfully didn’t serve as a catalyst for breakup. (That said, science has more to say on the predictions of any breakup in a relationship.)

But it’s hard to avoid the pressure of Valentine’s Day. This time of year, television, radio, printed publications and the internet are littered with advertisements reminding people of the upcoming celebration: Buy a gift! Make a reservation! Don’t forget the flowers! And by all means be romantic!.

Think you’re safe and single? Not so fast – ads urging those not in romantic relationships to seek one out (namely, via fee-based dating websites) are rife this time of year.

The origins of Valentine’s Day go back many centuries and it is a time of dubious repute. Originally it was a day set aside to celebrate Christian saints named Valentine (there were many). The association with romantic love was only picked up in the UK during the Middle Ages. Thank you, Chaucer and Shakespeare.

Mass-produced paper Valentines appeared on the scene in the 1800s, and it seems that the commercialisation of the day has increased ever since. Now, many refer to Valentine’s Day as a “Hallmark Holiday” – a reference to the popular producer of many Valentine’s cards.

No matter the history, or whether you are a conscientious objector to the commercialisation of love, it is difficult not to get swept up in the sentiment.

Despite the research (mentioned earlier) that Valentine’s Day can be calamitous for some, other research speaks to how to make this day a positive and beneficial one for you and your loved ones.

My funny Valentine

For those not in a romantic relationship, it’s hard to avoid the normative message that you are meant to be in one. But is it worth risking social rejection by asking someone for a date on Valentine’s Day?Unfortunately, science can’t answer that one. What we do know is that social rejection hurts –- literally – according to Professor Naomi Eisenberger, a social psychologist and director of the Social and Affective Neuroscience Laboratory at UCLA. She found that being socially rejected results in activation in the same brain areas that are active during physical pain.

Even though we may treat physical pain more seriously and regard it as the more valid ailment, the pain of social loss can be equally as distressing, as demonstrated by the activation of pain-related neural circuitry upon social disconnection.

A low dose of over-the-counter pain-killer can buffer against the sting of rejection. And, as silly as it seems, holding a teddy bear after the fact can provide relief.

If you do decide to seek a partner, dating websites and smartphone apps are a popular option. In 2013, 38% of American adults who were “single and looking” used dating websites or apps.

Dating websites such as eHarmony even claim to use scientific principles in their matching system (though this claim has been heavily critiqued by relationship researchers).

On this point, US psychology professor Eli Finkel provides a timely commentary on smartphone dating apps such as Tinder. He says he can see the benefits but he also points out that “algorithm matchmaking” is still no substitute for the real encounter.

As almost a century of research on romantic relationships has taught us, predicting whether two people are romantically compatible requires the sort of information that comes to light only after they have actually met.

The multi-billion dollar dating website industry would have you think it is a path to true-love. Though the fact of the matter is, despite several studies, we simply don’t know if dating websites are any more effective than more traditional approaches to mate-finding. So, on this point, single-and-looking payer beware.

Can’t buy me love

Speaking of money, the consumerism surrounding Valentine’s Day is undeniable. Australians last year spent upwards of A$791 million on gifts and such. Americans are estimated to spend US$19 billion (A$24 billion) this year.

Spending in and of itself, however, isn’t a bad thing. It turns out it’s how you spend that matters.

First, given the choice between buying a thing and buying an experience – ongoing research by Cornell University’s psychology professor Thomas Gilovich favours opting for the latter. Chances are, you’ll be happier.

In the case of Valentine’s Day, spending on a shared experience will make your partner happier too – research from US relationship researcher Art Aron suggests that spending on a shared experience will reap more benefit than a piece of jewelry or a gadget, especially to the extent that this shared experience is new and exciting.

Second, if you’re going to part with that cash in the end, you might as well spend it on someone else. Across numerous experiments (see here, here, here, here and here), individuals instructed to spend on others experienced greater happiness than those instructed to spend the same amount on themselves.

The effect is even stronger if you spend that money on a strong social bond, such as your Valentine.

Third, if you do give a gift, you’re best to pay heed to any dropped hints by your partner about desired gifts.

This is especially the case if your loved one is a man. In one study, men who received an undesired gift from their partners became pessimistic about the future of their relationship. Women didn’t react quite so poorly to a bad gift.

All you need is love

Of course, don’t think that love is just for lovers – even on Valentine’s Day.

Love Actually anyone?

Given the robustly supported conclusion that close non-romantic friendships can be just as rewarding (and health promoting) as romantic relationships, an alternative is to treat Valentine’s Day as an opportunity to celebrate all of your social relationships.

Scientific research supports the benefits of the following, simple (and free) acts:

  • a thank you note can boost relationships of all types

  • a hug can make both parties happier and even less stressed

  • simply engaging in chit-chat with those around you could be extremely rewarding

  • just a few minutes of loving-kindness mediation – wishing for happiness for yourself and those around you – can lead to a sense of deeper connection with others.

If all else fails on Valentine’s Day, then settle back and listen to Stephen Stills’ classic song Love The One You’re With: “If you can’t be with the one you love, love the one you’re with.”The Conversation

What is PNF stretching, and will it improve my flexibility?

Whether improving your flexibility was one of your new year’s resolutions, or you’ve been inspired watching certain tennis stars warming up at the Australian Open, maybe 2025 has you keen to focus on regular stretching.

However, a quick Google search might leave you overwhelmed by all the different stretching techniques. There’s static stretching and dynamic stretching, which can be regarded as the main types of stretching.

But there are also some other potentially lesser known types of stretching, such as PNF stretching. So if you’ve come across PNF stretching and it piques your interest, what do you need to know?

What is PNF stretching?

PNF stretching stands for proprioceptive neuromuscular facilitation. It was developed in the 1940s in the United States by neurologist Herman Kabat and physical therapists Margaret Knott and Dorothy Voss.

PNF stretching was initially designed to help patients with neurological conditions that affect the movement of muscles, such as polio and multiple sclerosis.

By the 1970s, its popularity had seen PNF stretching expand beyond the clinic and into the sporting arena where it was used by athletes and fitness enthusiasts during their warm-up and to improve their flexibility.

Although the specifics have evolved over time, PNF essentially combines static stretching (where a muscle is held in a lengthened position for a short period of time) with isometric muscle contractions (where the muscle produces force without changing length).

PNF stretching is typically performed with the help of a partner.

There are 2 main types

The two most common types of PNF stretching are the “contract-relax” and “contract-relax-agonist-contract” methods.

The contract-relax method involves putting a muscle into a stretched position, followed immediately by an isometric contraction of the same muscle. When the person stops contracting, the muscle is then moved into a deeper stretch before the process is repeated.

For example, to improve your hamstring flexibility, you could lie down and get a partner to lift your leg up just to the point where you begin to feel a stretch in the back of your thigh.

Once this sensation eases, attempt to push your leg back towards the ground as your partner resists the movement. After this, your partner should now be able to lift your leg up slightly higher than before until you feel the same stretching sensation.

This technique was based on the premise that the contracted muscle would fall “electrically silent” following the isometric contraction and therefore not offer its usual level of resistance to further stretching (called “autogenic inhibition”). The contract-relax method attempts to exploit this brief window to create a deeper stretch than would otherwise be possible without the prior muscle contraction.

The contract-relax-agonist-contract method is similar. But after the isometric contraction of the stretched muscle, you perform an additional contraction of the muscle group opposing the muscle being stretched (referred to as the “agonist” muscle), before the muscle is moved into a static stretch once more.

Again, if you’re trying to improve hamstring flexibility, immediately after trying to push your leg towards the ground you would attempt to lift it back towards the ceiling (this bit without partner resistance). You would do this by contracting the muscles on the front of the thigh (the quadriceps, the agonist muscle in this case).

Likewise, after this, your partner should be able to lift your leg up slightly higher than before.

The contract-relax-agonist-contract method is said to take advantage of a phenomenon known as “reciprocal inhibition.” This is where contracting the muscle group opposite that of the muscle being stretched leads to a short period of reduced activation of the stretched muscle, allowing the muscle to stretch further than normal.

What does the evidence say?

Research has shown PNF stretching is associated with improved flexibility.

While it has been suggested that both PNF methods improve flexibility via changes in nervous system function, research suggests they may simply improve our ability to tolerate stretching.

It’s worth noting most of the research on PNF stretching and flexibility has focused on healthy populations. This makes it difficult to provide evidence-based recommendations for people with clinical conditions.

And it may not be the most effective method if you’re looking to improve your flexibility in the long term. A 2018 review found static stretching was better for improving flexibility compared to PNF stretching. But other research has found it could offer greater immediate benefits for flexibility than static stretching.

At present, similar to other types of stretching, research linking PNF stretching to injury prevention and improved athletic performance is relatively inconclusive.

PNF stretching may actually lead to small temporary deficits in performance of strength, power, and speed-based activities if performed immediately beforehand. So it’s probably best done after exercise or as a part of a standalone flexibility session.

How much should you do?

It appears that a single contract-relax or contract-relax-agonist-contract repetition per muscle, performed twice per week, is enough to improve flexibility.

The contraction itself doesn’t need to be hard and forceful – only about 20% of your maximal effort should suffice. The contraction should be held for at least three seconds, while the static stretching component should be maintained until the stretching sensation eases.

So PNF stretching is potentially a more time-efficient way to improve flexibility, compared to, for example, static stretching. In a recent study we found four minutes of static stretching per muscle during a single session is optimal for an immediate improvement in flexibility.

Is PNF stretching the right choice for me?

Providing you have a partner who can help you, PNF stretching could be a good option. It might also provide a faster way to become more flexible for those who are time poor.

However, if you’re about to perform any activities that require strength, power, or speed, it may be wise to limit PNF stretching to afterwards to avoid any potential deficits in performance.The Conversation

Five healthy diet staples that may interact with prescription drugs

Grapefruit juice may cause some prescription drugs to accumulate in the body. KudPhotoCreate/ Shutterstock Dipa Kamdar, Kingston University

One of the most popular new year’s resolutions is making a commitment to healthier eating. Whether that’s eating more fruits and vegetables, cutting down on meat consumption or even becoming a vegetarian or vegan a few days a week.

While there are many benefits that can come from following a healthier diet, it’s important that any diet changes are made carefully. This is especially true if you’re someone who takes a prescription drug, as many health food staples can negatively interact with them.

Here are some common foods and drinks interactions you should know about:

1. Grapefruit juice:

To break down some prescription drugs in the body, the liver uses enzymes called cytochrome P450. But grapefruit juice contains chemical compounds called furanocoumarins which can block the action of these enzymes. If this happens, some drugs can accumulate in the body.

This includes ciclosporin, a drug that’s commonly used to prevent organ transplant rejection and manage symptoms of rheumatoid arthritis and skin conditions such as psoriasis. A build-up of ciclosporin can cause many side-effects, ranging from mild nausea and vomiting to kidney and liver damage.

Statins, often used to treat high cholesterol levels and prevent heart attacks and strokes, can also be affected by grapefruit juice through the same mechanism. Increased statin levels in the body can raise the risk of side-effects, including muscle breakdown, which is rare but serious.

Many other drugs can potentially interact with grapefruit juice as well – including amlodipine (a common high blood pressure drug) and sildenafil (an erectile dysfunction drug). If you take any of these prescriptions drugs, it’s best to talk to your doctor or pharmacist before drinking even small amounts of grapefruit juice. It may even be best to avoid it altogether.

2. Pomegranate and cranberry juice:

Many fruits and fruit juices – especially from the citrus family – can affect the breakdown of drugs in the liver.

Pomegranate juice is also shown to block the liver enzymes which break down the anticoagulant drug warfarin. The drug is used to prevent blood clots from forming in people with heart arrhythmias such as atrial fibrillation or deep vein thrombosis.

Some reported cases suggest that pomegranate juice might increase the international normalised ratio (INR – the time taken for blood to clot) in patients taking warfarin. This means patients may be at higher risk of bleeding.

Pomegranate juice may also affect other drugs, such as tacrolimus, an anti-rejection drug used in organ transplants.

Similarly, a number of case reports suggest cranberry juice can also affect warfarin. There has been one reported death of a patient from bleeding after they had drunk cranberry juice for two weeks prior while taking warfarin.

But results from various studies are mixed – with some showing cranberry affects warfarin in the body while others don’t show any effect. Because of this, it may be worth checking the INR more often if you drink these juices or consider that any fluctuations in INR may be due to fruit juices.

3. Green leafy vegetables:

Spinach, broccoli and kale are often hailed as healthy foods because they’re filled with nutrients while being low in calories. However, they’re also high in vitamin K, which is needed to activate certain clotting factors (proteins in the blood which help it clot).

This may be problematic for patients taking warfarin. Warfarin works by blocking vitamin K in order to prevent blood clots from forming. But eating foods rich in vitamin K can lower your INR and increase the risk of developing a blood clot.

It’s important to have a healthy diet – but be sure to monitor your INR levels or speak to your doctor if you do introduce more vitamin K-rich foods into your diet.

4. Milk:

Milk and dairy-rich foods such as cheese and yoghurt are all good sources of protein and calcium – a mineral required for healthy bones.

But these foods can affect the absorption of some drugs in the gut. This includes antibiotics such as some tetracyclines and ciprofloxacin. The calcium in the milk can bind to the antibiotic, meaning it cannot be absorbed into the bloodstream. This means the body will not get the full dose of antibiotic – making it harder for it to fight the infection.

Other drugs affected by dairy include levothyroxine, a drug used for patients with low thyroid levels.

But as these interactions happen in the gut, this means you can still have dairy even if you take these drugs. In most cases, you just need to leave at least a two-hour gap either before or after taking the drug before consuming dairy.

5. Beans:

Beans are considered healthy as they’re high in fibre and vitamins and minerals. Beans are also a great source of plant-based protein.

But soybeans, broad beans (fava beans) and snow peas may be high in tyramine. While tyramine is a substance naturally found in the body and in certain foods (such as aged cheeses, cured meats and fermented foods), it can interact with the antidepressant phenelzine.

Phenelzine is a monoamine oxidase inhibitor antidepressant (MAOI), which is less commonly used nowadays. The drug blocks enzymes which break down tyramine in the body. If patients eat tyramine-rich foods, this may result in high levels of tyramine, potentially leading to a dangerous rise in blood pressure. Only MAOI antidepressants, such as phenelzine, isocarboxazid, tranylcypromine, are affected by tyramine.

A healthy diet can improve your overall health in many ways. Just be sure to consult with a doctor of pharmacist before drastically changing your diet – particularly if you take prescription medications.The Conversation

New research shows how long, hard and often you need to stretch to improve your flexibility

Can you reach down and touch your toes without bending your knees? Can you reach both arms overhead? If these sound like a struggle, you may be lacking flexibility.

Flexibility is the ability to move a joint to through its full range of motion. It helps you perform most sporting activities and may prevent muscle injuries. And because most daily activities require a certain amount of flexibility (like bending down or twisting), it will help you maintain functional independence as you age.

Although there are many types of stretching, static stretching is the most common. It involves positioning a joint to lengthen the muscles and holding still for a set period – usually between 15 and 60 seconds. An example would be to stand in front of a chair, placing one foot on the chair and straightening your knee to stretch your hamstrings.

Static stretching is widely used to improve flexibility. But there are no clear recommendations on the optimal amount required. Our new research examined how long, how hard and how often you need to stretch to improve your flexibility – it’s probably less than you expect.

Assessing the data

Our research team spent the past year gathering data from hundreds of studies on thousands of adults from around the world. We looked at 189 studies of more than 6,500 adults.

The studies compared the effects of a single session or multiple sessions of static stretching on one or more flexibility outcomes, compared to those who didn’t stretch.

How long?

We found holding a stretch for around four minutes (cumulatively) in a single session is optimal for an immediate improvement in flexibility. Any longer and you don’t appear to get any more improvement.

For permanent improvements in flexibility, it looks like you need to stretch a muscle for longer – around ten minutes per week for the biggest improvement. But this doesn’t need to occur all at once.

How hard?

You can think of stretching as being hard, when you stretch into pain, or easy, when the stretch you feel isn’t uncomfortable.

The good news is how hard you stretch doesn’t seem to matter – both hard (stretching to the point of discomfort or pain) and easy stretching (stretching below the point of discomfort) equally improve flexibility.

How often?

If you are looking to improve your flexibility, it doesn’t matter how often you stretch each week. What is important is that you aim for up to ten minutes per week for each muscle that you stretch.

So, for example, you could stretch each muscle for a little more than one minute a day, or five minutes twice a week.

The amount of time you should spend stretching will ultimately depend on how many muscles you need to stretch. If you are less flexible, you will likely need to dedicate more time, given you’ll have more “tight” muscles to stretch compared to someone more flexible.

Can everyone improve their flexibility?

Encouragingly, it doesn’t matter what muscle you stretch, how old you are, your sex, or whether you are a couch potato or an elite athlete – everyone can improve their flexibility.

Static stretching can be done anywhere and at any time. And you don’t need any equipment. You can stretch while watching your favourite TV show, when in the office, or after walking the dog to help you relax. It’s a great way to start and end your day.

Although the exact stretches needed will depend on which muscles are “tight”, examples of some very common stretches include:

  • placing one foot upon on bench and leaning forward at the waist while keeping your knee straight to stretch your hamstrings
  • bending your knee and holding your ankle against your buttock to stretch your quadriceps muscles
  • reaching one arm while bending your elbow to stretch your triceps muscles.

However, the best advice is to visit a qualified health professional, such as a physiotherapist or exercise physiologist, who can perform an assessment and prescribe you a list of stretches specific to your individual needs.

As you can see, it really isn’t too much of a stretch to become more flexible.The Conversation

Is stress turning my hair grey?

 

When we start to go grey depends a lot on genetics.

Your first grey hairs usually appear anywhere between your twenties and fifties. For men, grey hairs normally start at the temples and sideburns. Women tend to start greying on the hairline, especially at the front.

The most rapid greying usually happens between ages 50 and 60. But does anything we do speed up the process? And is there anything we can do to slow it down?

You’ve probably heard that plucking, dyeing and stress can make your hair go grey – and that redheads don’t. Here’s what the science says.

What gives hair its colour?

Each strand of hair is produced by a hair follicle, a tunnel-like opening in your skin. Follicles contain two different kinds of stem cells:

  • keratinocytes, which produce keratin, the protein that makes and regenerates hair strands
  • melanocytes, which produce melanin, the pigment that colours your hair and skin.

There are two main types of melanin that determine hair colour. Eumelanin is a black-brown pigment and pheomelanin is a red-yellow pigment.

The amount of the different pigments determines hair colour. Black and brown hair has mostly eumelanin, red hair has the most pheomelanin, and blonde hair has just a small amount of both.

So what makes our hair turn grey?

As we age, it’s normal for cells to become less active. In the hair follicle, this means stem cells produce less melanin – turning our hair grey – and less keratin, causing hair thinning and loss.

As less melanin is produced, there is less pigment to give the hair its colour. Grey hair has very little melanin, while white hair has none left.

Unpigmented hair looks grey, white or silver because light reflects off the keratin, which is pale yellow.

Grey hair is thicker, coarser and stiffer than hair with pigment. This is because the shape of the hair follicle becomes irregular as the stem cells change with age.

Interestingly, grey hair also grows faster than pigmented hair, but it uses more energy in the process.

Can stress turn our hair grey?

Yes, stress can cause your hair to turn grey. This happens when oxidative stress damages hair follicles and stem cells and stops them producing melanin.

Oxidative stress is an imbalance of too many damaging free radical chemicals and not enough protective antioxidant chemicals in the body. It can be caused by psychological or emotional stress as well as autoimmune diseases.

Environmental factors such as exposure to UV and pollution, as well as smoking and some drugs, can also play a role.

Melanocytes are more susceptible to damage than keratinocytes because of the complex steps in melanin production. This explains why ageing and stress usually cause hair greying before hair loss.

Scientists have been able to link less pigmented sections of a hair strand to stressful events in a person’s life. In younger people, whose stems cells still produced melanin, colour returned to the hair after the stressful event passed.

4 popular ideas about grey hair – and what science says

1. Does plucking a grey hair make more grow back in its place?

No. When you pluck a hair, you might notice a small bulb at the end that was attached to your scalp. This is the root. It grows from the hair follicle.

Plucking a hair pulls the root out of the follicle. But the follicle itself is the opening in your skin and can’t be plucked out. Each hair follicle can only grow a single hair.

It’s possible frequent plucking could make your hair grey earlier, if the cells that produce melanin are damaged or exhausted from too much regrowth.

2. Can my hair can turn grey overnight?

Legend says Marie Antoinette’s hair went completely white the night before the French queen faced the guillotine – but this is a myth.

Melanin in hair strands is chemically stable, meaning it can’t transform instantly.

Acute psychological stress does rapidly deplete melanocyte stem cells in mice. But the effect doesn’t show up immediately. Instead, grey hair becomes visible as the strand grows – at a rate of about 1 cm per month.

Not all hair is in the growing phase at any one time, meaning it can’t all go grey at the same time.

3. Will dyeing make my hair go grey faster?

This depends on the dye.

Temporary and semi-permanent dyes should not cause early greying because they just coat the hair strand without changing its structure. But permanent products cause a chemical reaction with the hair, using an oxidising agent such as hydrogen peroxide.

Accumulation of hydrogen peroxide and other hair dye chemicals in the hair follicle can damage melanocytes and keratinocytes, which can cause greying and hair loss.

4. Is it true redheads don’t go grey?

People with red hair also lose melanin as they age, but differently to those with black or brown hair.

This is because the red-yellow and black-brown pigments are chemically different.

Producing the brown-black pigment eumelanin is more complex and takes more energy, making it more susceptible to damage.

Producing the red-yellow pigment (pheomelanin) causes less oxidative stress, and is more simple. This means it is easier for stem cells to continue to produce pheomelanin, even as they reduce their activity with ageing.

With ageing, red hair tends to fade into strawberry blonde and silvery-white. Grey colour is due to less eumelanin activity, so is more common in those with black and brown hair.

Your genetics determine when you’ll start going grey. But you may be able to avoid premature greying by staying healthy, reducing stress and avoiding smoking, too much alcohol and UV exposure.

Eating a healthy diet may also help because vitamin B12, copper, iron, calcium and zinc all influence melanin production and hair pigmentation.The Conversation
