In 1982, the term “shinrin-yoku” or “forest bathing” was coined by the Japanese Ministry of Agriculture, Forestry, and Fisheries. Researchers studied the physiological benefits of a forest atmosphere and found that forests could lower concentrations of cortisol, lower pulse rate, lower blood pressure, increase parasympathetic nerve activity, and lower sympathetic nerve activity. The data confirmed what many cultures have always known: the natural environment can enhance human health (Park et. al).

Forests have the ability to enhance quality of life and reduce public health care costs. Stress is one of the leading causes of noncommunicable diseases, such as cardiovascular, metabolic, immunological, oncological, and psychiatric disorders (Doimo et. al). A single visit to a forest can influence psychological responses via the sense and decrease the perceived effects of stress, anxiety, and other negative emotions. Urban stimuli, compared to natural stimuli, do not allow the mind to relax in the same ways. Natural environments allow the mind to wander and be soothed by the sound of birds and rustling leaves, rather than jostled by the sound of traffic (Schertz et. al). 

Our brains require downtime to restore motivation, and creativity and remember valuable information that we have learned throughout the day. According to research, nature restores our attention, helps with our memory recall, and increases relaxation (Doimo et. al). Rest is essential for the cognitive and emotional health of humans of all ages. Studies have found a positive association between green space around schools and cognitive development in children, greatly attributing this to reduced exposure to air pollution (Dadvand et. al). Due to deforestation and development, nature experiences are increasingly difficult to access. It is vital that we conserve green space and urban forests, not only for climate resiliency but for “fighting stress and improving wellbeing in general” (Doimo et. al).
