Psychologically, contact with nature has been proven to reduce stress and improve mental health. The Japanese practice of “forest bathing” or shinrin-yoku involves spending time in wooded areas to boost mood and lower cortisol levels. Similarly, a 2019 study published in _Scientific Reports_ showed that spending at least 120 minutes per week in nature was associated with good health and psychological well-being. Even small exposures, such as viewing trees from an office window, can reduce anxiety.
