The Japanese word for forest bathing is shinrin-yoku: Shinrin-yoku is a Japanese practice that involves spending time in a forest to relax and connect with nature. It involves being calm and quiet, breathing deeply, and observing the natural surroundings. The practice is said to have many health benefits, including reducing stress and anxiety, improving mood, and helping with insomnia and post-traumatic stress disorder. Japan's national health service has included shinrin-yoku as an intervention for mental health.
