Nature therapy (a broader term than related forest bathing or Shinrin-Yoku) which describes the practice that combines a range of exercises and tasks in an outdoor environment. As of today, there appear various definitions of what nature therapy comprises. Garden therapy, horticultural therapy, Kneipp therapy or even ocean therapy may be viewed as forms of nature therapy.
A 2012 systematic review study showed inconclusive results related to methodological issues across the literature. Subsequently, a 2017 systematic review of the benefits of spending time in forests demonstrated positive health effects, but not enough to generate clinical practice guidelines. Many individual studies do promote health benefits of forest therapy or forest bathing.
Anthropologically, nature therapy appears to have existed since the dawn of time in many cultures and tribes. Shinrin-yoku (森林浴) literally means forest bathing, originated in Japan in the early 1980s and may be regarded as a form of nature therapy. In Japan, Shinrin-yoku has become established across all prefectures with more than 60 Forest Therapy Camps by the end of 2016.
In the late 1990s a pseudoscientific variant called earthing or grounding started to be marketed, under the notion that the earth functions as an electrical ground for people and that touching the earth provides an array of health benefits based on an incorrect understanding of antioxidant activity.
