In today's fast-paced, industrialized societies, mental health issues such as anxiety and depression are becoming increasingly common. As people experience more disconnection from nature, the toll on emotional well-being grows. However, recent studies suggest that living closer to nature—either through forest therapy or lifestyles like those of hunter-gatherers—offers profound benefits for mental health. Let's explore the science behind these findings and see how we can apply them in modern life.
Forest Therapy: A Proven Nonpharmacological Intervention
Forest-based interventions, also known as forest therapy or "Shinrin-yoku" (forest bathing), have garnered attention as an alternative therapy for improving mental health. A meta-analysis of randomized controlled trials found that spending time in forest environments significantly reduces symptoms of depression, anxiety, and other negative emotions, while also boosting positive mental states like vitality.
Depression and Anxiety: The study revealed a 36% greater reduction in depression symptoms and a 12% drop in anxiety levels among participants who engaged in forest therapy compared to control groups(Med Xpress).
Positive and Negative Emotions: Forest therapy also led to a 9% increase in positive emotions like vigor and a 37% reduction in negative emotions such as stress and fatigue(Med Xpress).
The typical exposure time to nature during these interventions ranges from 2 hours to several days, with activities such as walking, meditating, and experiencing nature through all five senses. This immersive experience in nature is critical for achieving mental health benefits.
Hunter-Gatherer Lifestyles and Mental Health
Hunter-gatherer societies, such as the Hadza in Tanzania or the Aka people of the Congo Basin, provide insights into how living closely with nature can contribute to mental well-being. Research shows that these communities experience significantly lower rates of mental illness due to their lifestyle factors(Cambridge University Press & Assessment (Medical Daily).
Physical Activity: Hunter-gatherers spend 2 to 3 hours per day engaged in moderate to vigorous physical activity, which has been shown to improve mental health by reducing stress and anxiety. In contrast, many people in modern societies lead sedentary lives, contributing to rising rates of depression and anxiety (Medical Daily)(Med Xpress).
Social Connections: These societies are known for their tight-knit communities, where social support is abundant. Strong social bonds are protective against mental health issues like depression, as they reduce feelings of isolation and provide emotional safety nets(Medical Daily).
Natural Rhythms and Low Chronic Stress: Living in harmony with natural cycles—sunrise, sunset, and seasons—helps regulate circadian rhythms, reducing stress and anxiety. Furthermore, hunter-gatherer societies typically experience less chronic stress, as their egalitarian structures minimize competition and promote communal well-being(Cambridge University Press & Assessment)(Medical Daily).
Application at Our Retreats
At our retreats, we have incorporated the healing power of nature by carving out forest paths specifically designed to enhance the benefits of forest therapy. These paths offer a safe and serene environment for mindful walking, meditation, and immersion in the natural surroundings. Participants can enjoy the same therapeutic effects seen in research—improvements in mood, reductions in stress, and increased mental clarity—all while embracing the peaceful sounds and sights of the forest.
The carved-out trails allow guests to experience nature through guided or self-directed activities, ensuring that the positive effects of forest therapy are fully realized. This not only enhances physical health through movement but fosters deep emotional well-being by reconnecting with the natural world.
Lessons for Modern Society
Reconnect with Nature: Whether through forest therapy or regular outdoor activities, spending time in nature can significantly improve mental health. Studies show that even viewing natural scenes can lower stress levels and elevate mood.(Med Xpress)
Prioritize Physical Activity: Incorporating physical movement into daily routines, such as walking, hiking, or exercising in green spaces, mimics the activity levels of hunter-gatherer societies and promotes better mental and physical health.
Build Strong Social Bonds: Just as hunter-gatherers benefit from close community ties, modern individuals can enhance mental health by nurturing supportive relationships. This sense of belonging reduces feelings of loneliness, a key contributor to depression and anxiety.

Adopt a Natural Diet: Hunter-gatherers' whole-food diets, rich in plants and lean meats, provide mental and physical health benefits. Reducing processed foods and adopting a more natural diet can decrease the risk of mental health issues linked to poor nutrition.
Conclusion
Both forest therapy and hunter-gatherer lifestyles show us the powerful connection between nature and mental health. By integrating elements of these practices—such as spending time outdoors, staying physically active, building strong social networks, and following a whole-food diet—modern society can find effective, nonpharmacological ways to improve mental well-being and reduce the growing burden of mental health disorders.
