JUST ONE HOUR IN GREEN SPACE A WEEK COULD LIFT YOUR MOOD, NEW STUDY FINDS
If you have ever come home from a walk in the park feeling lighter, science is now putting a number on just how much green space your mind needs.
A new study suggests that spending just one hour a week among greenery could deliver half of the mental health benefit nature has to offer.
The findings, released this week by researchers at the University of Hong Kong, could make it easier for busy women to build a little nature into their week.
What The Green Space Study Found
The research team pooled 45 years of global evidence, drawing on studies published between 1980 and 2025.
They wanted to answer a simple question that many of us have wondered about: how much time outdoors is enough?
Their analysis, published in the Journal of Environmental Psychology, found a clear dose-response pattern.
One visit or one hour of green space a week delivered about 50 per cent of the maximum mental health benefit the researchers estimated.
Around four visits or four hours a week lifted that to about 90 per cent.
Roughly six visits or eight hours a week reached about 99 per cent.
Importantly, the time adds up across the week, so it does not need to be all in one go.
Nature As Free Medicine
Study leader Professor Bin Jiang described nature as "a free, accessible 'medicine' for mental health", according to the university's announcement.
Co-author Professor Gunter Schumann said the one-hour threshold was highly realistic for people experiencing low mood or reduced energy.
That is encouraging news for anyone juggling work, children, ageing parents and everything in between.
First author Dr Jiali Li suggested people start with a routine they can sustain, such as a weekly park walk.
Easy Ways To Fit In More Green Space
The good news is that you do not need a national park on your doorstep to reach that first hour.
Try a 20-minute walk through a local park three times a week, and you have already hit the target.
Swap a coffee catch-up at a cafe for a takeaway cup and a stroll around the botanic gardens.
Take your lunch break outdoors and find a bench under a tree rather than eating at your desk.
Turn the school run or dog walk into a slightly longer loop that passes through a leafy reserve.
Book a weekend bushwalk, beach-side reserve wander or picnic with friends as a regular date.
Get your hands dirty in the garden, on the balcony or at a community garden.
As the weather warms up, early morning and evening walks can be a lovely way to avoid the heat while enjoying the outdoors.
Making It A Habit
Like most healthy habits, consistency matters more than perfection.
Pop your green space time into your diary the way you would any other appointment.
Invite a friend, partner or neighbour along, which can add a welcome dose of connection too.
Leave your phone in your pocket, notice the birdsong and the smell of the trees, and let your mind wander.
If you are short on time, remember that the researchers found the biggest jump in benefit comes from that very first hour.
When To Seek Extra Support
Time in nature is a wonderful boost for wellbeing, but it is not a replacement for professional help.
If you have been feeling low, anxious or flat for more than a couple of weeks, speak to your GP, who can talk you through your options.
You can also call Beyond Blue on 1300 22 4636 or Lifeline on 13 11 14 any time of the day or night.
For everyone else, the message from this research is refreshingly simple.
Lace up your walking shoes, step outside and give yourself an hour among the trees this week.
Your mind may well thank you for it.
