Imagine that your doctor prescribes you a new treatment. Itās pleasant and enjoyable, and you can have as much as you want. Potential side effects include spontaneous euphoria and being in a good mood. Not to mention, itās free and available all around you.
Itās not a drug or some other medical procedure that your doctor has recommended. Instead, it is a ānature prescriptionā ā a recommendation to spend time in nature.
Researchers from UNSW Sydney assessed international evidence for nature prescriptions and their ability to improve health. They analysed 28 studies that tested nature prescriptions in real-world patients. This research was led byĀ Professor Xiaoqi FengĀ from UNSW Medicine & Health andĀ from theĀ , who are the Co-Directors of theĀ (±Ź“Ē·É±š°ł³¢²¹²ś).Ģż

The systematic review and meta-analysis, published today in , found that nature prescriptions provided both physical and mental health benefits. Patients had reduced blood pressure, as well as lower depression and anxiety scores ā and they had a higher daily step count. Ā
āThe evidence shows that nature prescriptions can help to restore and build capacities for better physical and mental health. What we need now is to work out how to make nature prescriptions happen in a sustained way for those people with high potential to benefit, but who currently spend little time in nature,ā said Prof. Feng.
Research shows that contact with nature reduces harms, including those from poor air quality, heatwaves, and chronic stress, while encouraging healthy behaviours such as socialising and . This can help to prevent issues including, and .
āThis study is built upon a long-term program of research that we are doing, where we show contact with nature ā and trees especially ā is really good for strengthening mental and physical health across our lives,ā said Prof. Feng.

Previous research by Prof. Feng shows that living close to certain types of green space can improve health. For example, in a in New South Wales (NSW), those living in areas with 30 per cent or more tree canopy reported better general health and reduced psychological distress. This research has informed the City of Sydneyās to reach 40 per cent green cover by 2050.Ā
āBut even if you have a high-quality green space like a park nearby, it doesnāt mean that everyone will visit and benefit from it,ā said Prof. Feng.
āHow can we encourage and enable people to (re)connect with nature? Thatās where the idea of a nature prescription comes in.ā
Nature prescriptions are emerging as a supplement to standard medical care. For example, the UK Government recently invested Ā£5.77 million in a and Canada has a .
In Australia, there is growing public interest in nature prescriptions. A of Australian adults led by Prof. Feng showed that over 80 per cent of people were receptive to the idea.
However, there are no large-scale nature prescription programs in Australia yet. More research is needed to understand how nature prescriptions could be implemented in our local context.
āSo how long should the nature prescription be for? What should be in the prescription? How should we deliver it, and by whom? These questions donāt have firm answers yet,ā said Prof. Feng.
āIf we want nature prescriptions to become a national scheme, we really need to provide the evidence.ā
Itās also important for nature prescriptions to be accessible to all Australians. from Prof. Astell-Burt and Prof. Feng has shown that low-income communities are least likely to have access to green space. Yet, these communities are more at risk of chronic health issues like type 2 diabetes, obesity and cardiovascular disease.
āWe donāt want nature prescriptions to be a luxury item for the rich who already have access to beaches and a lot of high-quality green space,ā Prof. Feng said. āWe want these benefits for everyone.ā
