In the serene surroundings of Pensford Field in Kew, west London, a unique initiative is reshaping mental health support through nature. Spearheaded by psychologist Dr Alison Greenwood, the charity Dose of Nature, established in 2018, has emerged as a beacon of hope for those facing various mental health challenges, including depression and addiction. The charity operates on a simple yet profound principle: reconnecting individuals with nature can foster significant improvements in mental well-being.

Dose of Nature invites referrals from general practitioners (GPs) and offers a therapeutic approach that stands out for its integration of professional mental health support and direct interaction with the natural environment. Through the programme, individuals receive initial assessments conducted outdoors—irrespective of the weather—by Greenwood or another psychologist. Greenwood asserts that such exposure, even under less-than-ideal conditions, can be beneficial, stating, “Getting wet, getting cold can be really good for the brain and body.”

Central to this model is the role of trained volunteer “nature guides” who accompany participants on their journeys. These guides provide support, ensuring that participants feel safe and can discuss their experiences confidentially. This aspect not only fosters a stronger connection with nature but also alleviates some of the burdens placed on traditional mental health services.

The cost-effectiveness of Dose of Nature’s services has made it particularly appealing in the context of the current NHS landscape, which is grappling with lengthy waiting lists and strained resources. Whereas a ten-week course of cognitive behavioural therapy through the NHS can cost approximately £1,350, Dose of Nature offers its programme for between £400 and £500. Greenwood notes that independent studies have shown a 40% reduction in GP contacts among patients who have completed the programme, highlighting its potential to ease the demand on healthcare providers.

The success of the charity is not merely anecdotal. Research, including a study from the London School of Economics, has demonstrated substantial improvements in participants’ mental health, with marked decreases in anxiety and depression scores. In a recent assessment, participants reported significantly higher levels of life satisfaction and a greater sense of purpose compared to a control group awaiting treatment.

The therapeutic principles underlying Dose of Nature echo international movements advocating for “forest medicine” or “forest bathing,” a practice that emphasises immersive experiences in natural settings to promote health and well-being. This concept, widely recognised in countries such as Japan and South Korea, draws on substantial scientific evidence that supports the mental and physical health benefits of spending time in nature. Research highlights that exposure to natural environments can significantly lower stress levels and boost immune responses, suggesting a profound connection between our mental states and the natural world.

Individuals who have participated in Dose of Nature’s programme have shared transformative experiences. For instance, Elaine Lester, who has battled mental health challenges following years of abuse, describes the open-air activities as pivotal in fostering self-confidence she never believed possible. Similarly, Tom Krumins, diagnosed with bipolar disorder, notes the clarity and grounding provided through the natural surroundings, which have helped manage his symptoms more effectively.

This innovative charity continues to thrive by gathering support from local authorities, NHS partnerships, and charitable donations, ensuring its services remain accessible and free for participants. As urban environments increasingly consume natural spaces, initiatives like Dose of Nature remind us of the essential role nature plays in nurturing mental health.

Emphasising that the therapeutic potential of nature is a phenomenon experienced across cultures and centuries, Greenwood highlights the project’s mission to inspire lasting lifestyle changes through deeper engagement with the natural environment. It serves not only as a remedy for individual distress but also as a community-driven approach to mental health, where the healing power of nature can indeed lead to collective well-being.

The model pioneered by Dose of Nature is a compelling example of how reconnecting with our natural surroundings can foster not only personal growth and healing but also potentially alleviate some of the systemic pressures faced by conventional healthcare systems. As the exploration of nature’s therapeutic benefits continues to gain traction, Dose of Nature stands at the forefront, offering hope and tangible support to those seeking a pathway towards improved mental health.
