Nature Prescriptions: How Time Outdoors Boosts Mental Health & Outperforms Therapy

The simple act of being outside – truly *noticing* the sunlight on your skin, the sound of birds, the patterns in tree bark – is emerging as a powerful, and surprisingly effective, treatment for mental illness. A London-based charity, Dose of Nature, is pioneering this approach, achieving recovery rates that outperform standard NHS talking therapies. For many, it’s not just a supplement to traditional care, but a genuine alternative.

A Different Kind of Prescription

Founded in 2018 by Dr. Alison Greenwood, a former NHS psychologist, Dose of Nature offers one-to-one courses that prescribe time in nature. Unlike many “green social prescribing” schemes, referrals come directly from GPs, signaling a growing recognition of the therapeutic value of the outdoors. The charity has already delivered 1,500 courses, with a 64% recovery rate – compared to 50% for standard NHS talking therapies – and an 86% reliable improvement rate versus the health service’s 69% according to recent NHS data.

The core of the program isn’t about strenuous hikes or remote wilderness experiences. Greenwood emphasizes that even a local park bench can be profoundly beneficial. The focus is on mindful engagement with the natural world – slowing down, observing details, and allowing the environment to calm the mind, and body. “What you’ve got there from the sun on your face is a massive boost of serotonin!” Greenwood explains, highlighting the immediate physiological benefits.

The Science Behind the Serenity

This isn’t simply anecdotal evidence. The Dose of Nature approach is grounded in an understanding of how humans evolved. As Greenwood points out, we spent millennia living *in* nature, and our brains and bodies are still wired to respond positively to natural stimuli. Trees and plants release phytoncides, compounds that boost the immune system. Natural sounds – water, wind, birdsong – have been shown to improve mood. Even the fractal patterns found in nature can aid recovery from stress and promote a relaxed state of mind by boosting alpha waves in the brain. Exposure to soil microorganisms can also positively impact mood.

Sal, a client of Dose of Nature who was diagnosed with a life-limiting illness and made redundant from her banking job, found the scientific explanation particularly helpful. “It was a real source of help to understand the science behind why nature is so positive for you – it’s not flim-flam and it’s not all lefty tree huggers,” she says.

From Hopelessness to Hope: Tom’s Story

The impact of Dose of Nature extends beyond physiological benefits. Tom Krumins, a softly spoken man who now works for the charity as an operations assistant, describes the program as life-changing. Diagnosed with bipolar disorder in his early 20s, Krumins had endured a cycle of highs and lows, including hospitalizations. “But every single time I’d have a session with my guide, I’d come away feeling so much better,” he recalls. Sessions often involved simple riverside walks, focusing on slowing down and appreciating the details of the environment – the light on the water, the rhythm of the current.

“I have never felt more enabled and more optimistic about the future,” Krumins says, adding that he hasn’t experienced a manic episode in three years. For him, the program offered a sense of stability and opportunity that had previously felt unattainable.

Cost-Effectiveness and Wider Impact

The benefits aren’t just personal; they’re also economic. An independent assessment by researchers at the London School of Economics found that the Dose of Nature prescription is not only clinically effective but also cost-effective. The study, which followed 375 people over two-and-a-half years, estimated that the social welfare benefits were worth eight times the cost of the prescription. Both increased nature connection and social connection were identified as important factors in recovery.

Dr. Faisal Islam, a GP at Cross Deep Surgery in Twickenham, has seen firsthand the positive impact of referring patients to Dose of Nature. He notes that it provides an alternative to medication, which doesn’t work for everyone, and addresses the long waiting lists for traditional NHS talking therapies like cognitive behavioral therapy (CBT). “Now we have got an alternative – it’s immediately in my thoughts when I assess a patient, along with medication and CBT. I honestly think it will save lives and improve patients’ mental health.”

Expanding Access to Nature’s Healing Power

Dose of Nature began in 2019 and now employs 11 staff, funded through a combination of NHS funding, local authorities, and charitable foundations. The charity is actively working to expand its reach, with a new hub in North Guildford and plans for projects in Hounslow and potentially Lincolnshire. The goal is to demonstrate the effectiveness of the approach in diverse settings and empower other groups to offer nature prescriptions.

“We’d love to spread it to as many people as possible,” says Greenwood. “What we have is for everybody. It’s not just for one section of society. What we are trying to show is that it will not only work best for you now, if you do it in a particular way, but will be there for you for the rest of your life. You don’t need to produce an appointment with nature.”

Looking ahead, Dose of Nature aims to continue gathering evidence to support the widespread adoption of nature-based interventions for mental health. The charity is also exploring ways to integrate its approach into existing healthcare systems and train more volunteer guides to meet the growing demand. The long-term vision is a future where access to nature is recognized as a fundamental component of mental wellbeing, available to all.
