Shinrin yoku

Forest bathing is the practice of taking a short, leisurely visit to a forest for health benefits.

The practice originated in Japan where it is called shinrin-yoku (森林浴) in Japanese (it is also called sēnlínyù (森林浴) in Mandarin and sanlimyok (산림욕) in Korean).

Studies in Japan have measured changes in immune markers and stress hormones in people who regularly walked in specific forests in Japan.

In addition, people with diabetes but not taking insulin found substantial benefits by lowering blood glucose levels.
