Simple and self-guided nature program quickly improves mood and reduces stress

A short, self-guided program built around everyday contact with nature reports meaningful gains in mood and stress after just four weeks. It is simple by design and aimed at adults with low wellbeing who want help they can start today.

The approach is called Roots and Shoots. It pairs at-home reflections with brief outdoor activities near where people live, adding light digital support for those who want it.

Nature helps improve mental health

The study was led by Dr. Matt Owens at the University of Exeter, with Clinical Psychologist Dr. Hannah L. I. Bunce, co-founders of the ROWAN nature and mental health research group.

Researchers across psychology, public health, and ecology have linked time in natural settings with improved attention, mood, and stress biology, forming a coherent picture of benefits to mental health.

Evidence extends across the life course, with large cohort work suggesting childhood access to greenspace predicts a lower risk of several psychiatric disorders in adulthood.

The adult intervention literature has moved from anecdotes to trials.

A comprehensive review finds nature-based interventions such as green exercise, gardening, and forest therapy improve mental health outcomes in adults, often with practical sessions of 20 to 90 minutes several times per week.

Prescribed contact with nature, from park walks to blue space visits, has also shown benefits for symptoms of depression and blood pressure in randomized and quasi-experimental studies.

Nature program activities

Roots and Shoots is a printed guidebook organized into six short sections that unfold over four weeks. It introduces the science of nature and wellbeing, then leads people through simple tracking of time in nature, mood, and values-based actions.

Core tools include a habit wheel for building small, repeatable moments outdoors, a coping tool to swap unhelpful routines for neutral ones, and a honeycomb challenge to notice different kinds of nature contact.

Brief meditations and breathing exercises are available online, supporting practice when getting outside is hard.

The study used a randomised controlled trial design. Adults with low wellbeing were assigned either to start the program or to a waitlist control and completed measures at baseline, two weeks, and four weeks.

Nature program results

On the primary outcome of wellbeing, the intervention group improved more than the waitlist group across four weeks, with a large effect size by the study end. The design was remote and light touch, yet the signal was clear.

Eighty-two percent of program completers made reliable improvements in wellbeing, and 59 percent met the threshold for clinically significant change. None showed deterioration.

Average scores on anxiety and depression started in the clinical range and shifted below caseness by week four.

Effects were medium for anxiety and small for depressive symptoms. Engagement and acceptability were high. Ninety four percent of those who finished said they would recommend the guidebook to a friend.

Practicing the program daily

Nature time is not treated as a luxury. It is framed as a small, daily behavior that can sit alongside existing routines and responsibilities.

The psychological ingredients are familiar and low cost. People practice mindfulness, track mood, write briefly, and connect actions to values that matter to them.

The program avoids all-or-nothing goals. It welcomes brief, nearby, and accessible encounters with trees, water, or sky, and includes virtual nature options when needed.

Why this matters for care

Self-help options can play a useful role when services are stretched and stigma or logistics make formal care harder to access. They also give people a way to start while they wait for more intensive support if needed.

Mental health problems cost the UK economy an estimated 118 billion pounds per year, about 5 percent of GDP, which makes low-cost, scalable options worth testing carefully.

A month-long guidebook that people can complete without appointments or travel is inexpensive to deliver at scale.

The team emphasizes that a booklet is not a substitute for clinical care in crisis. It is an early step that can help many people feel and function better while easing pressure on services.

Health systems increasingly look for stepped care and preventive options. If confirmed in larger trials, a short nature guide could sit at step 1 or step 2 and augment therapy as homework after higher-intensity care.

Nature program in science

“We have developed a self-help package that uses principles from both clinical psychology and nature research to empower individuals to spend more time in nature, rediscover their relationship with natural environments and improve their wellbeing,” said Dr. Owens.

Several streams of evidence propose why nature contact helps. Attention restoration, stress recovery, and social connection are all plausible, testable mechanisms.

Recent reviews point to dose and variety as practical levers. Short, regular sessions in green or blue spaces appear better than rare marathons, and mixing settings may matter as much as time logged.

Urban living need not be a barrier. Street trees, pocket parks, and canal paths can be enough to practice the habits described in the guide, especially when paired with brief indoor or virtual nature for consistency.

The structure here is the quiet shift. A light-touch plan that invites repeated, low-effort contact with nearby nature can build momentum without demanding free afternoons or long travel.

Next steps for this nature program

This was a pilot, so the next step is a larger, fully powered trial that tests durability, mechanisms, and who benefits most. Duration is an open question, since many participants said they would welcome a longer version.

Precision also matters. Some people may respond most to habit building outdoors, while others change more through mindfulness or values work.
