Nature therapy

  (Redirected from Forest bathing)

Nature therapy, sometimes referred to as ecotherapy, forest therapy, forest bathing, grounding, earthing, Shinrin-Yoku or Sami Lok, is a practice that describes a broad group of techniques or treatments to use nature to improve mental or physical health.

Spending time in nature has various physiological benefits such as relaxation.[1]


In the 6th century BCE, Cyrus the Great planted a garden in the middle of a city to increase human health.[2] In the 16th century CE, Paracelsus wrote: "The art of healing comes from nature, not from the physician."[3] Scientists in the 1950s looked into why people chose to spend time in nature.[4] The term Shinrin-yoku (森林浴) or forest bathing was coined by the head of the Japanese Ministry of Agriculture, Forestry, and Fisheries, Tomohide Akiyama, in 1982 to encourage more visitors to forests.[2][5][6][7][8]

Health effectsEdit


120 minutes in nature weekly could improve health and well-being.[9] As little as five minutes in a natural setting, improves mood, self-esteem, and motivation.[10] Nature therapy probably has a benefit in reducing stress and improving a person's mood.[11][12]

Forest therapy has been linked to some physiological benefits as indicated by neuroimaging and the Profile of mood states psychological test.[13]

Horticulture therapy has been linked to general well-being by boosting positive mood and escaping from daily life stressors.[12]

Stress and depressionEdit

Interaction with nature can decrease stress and depression.[12][2] Forest therapy might help stress management for all age groups.[14]

Social horticulture could help with depression and other mental health problems of PTSD, abuse, lonely elderly people, drug or alcohol addicts, blind people and other people with special needs.[15] Nature therapy could also improve self-management, self-esteem, social relations and skills, socio-political awareness and employability.[16] Nature therapy could reduce aggression and improve relationship skills.[17]

Other possible benefitsEdit

Nature therapy could help with general medical recovery, pain reduction, Attention Deficit/Hyperactivity Disorder, dementia, obesity, and vitamin D deficiency.[18]


A 2012 systematic review study showed inconclusive results related to the methodology used in studies.[19] Spending time in forests demonstrated positive health effects, but not enough to generate clinical practice guidelines or demonstrate causality.[20] Additionally, there are concerns from researchers expressing that time spent in nature as a form of regenerative therapy is highly personal and entirely unpredictable.[4] Nature can be harmed in the process of human interaction.[4]


Grounding, or earthing, is a pseudoscientific practice that involves people grounding themselves using devices by touching the earth or removing shoes.[21][22] People who ground themselves believe that they have been exposed to high levels of electromagnetic radiation.[23] Possible changes in mood could be due to a placebo effect.[24]

Governmental supportEdit

In Finland, researchers recommend five hours a month in nature to reduce depression, alcoholism, and suicide.[3] Forest therapy has state-backing in Japan.[14] South Korea has a nature therapy program for firefighters with post-traumatic stress disorder.[3]
