Your Brain on Nature: Forest Bathing and Reduced Stress

24 October 2016

 - Among the many reasons to preserve what is left of our ancient forests, the mental aspects stand tall. The notion that forests have a special place in the realm of public health, including an ability to refresh the weary, is not a new one. Medical doctors, including Franklin B. Hough, reported in early U.S. medical journals that forests have a “cheerful and tranquilizing influence which they exert upon the mind, more especially when worn down by mental labor.” Individuals report that forests are the perfect landscape to cultivate what are called transcendent experiences—these are unforgettable moments of extreme happiness, of attunement to that outside the self, and moments that are ultimately perceived as very important to the individual.

In 1982, the Forest Agency of the Japanese government premiered its shinrin-yoku plan. In Japanese shinrin means forest, and yoku, although it has several meanings, refers here to a “bathing, showering or basking in.” More broadly, it is defined as “taking in, in all of our senses, the forest atmosphere.” The program was established to encourage the populace to get out into nature, to literally bathe the mind and body in greenspace, and take advantage of public owned forest networks as a means of promoting health. Some 64 percent of Japan is occupied by forest, so there is ample opportunity to escape the megacities that dot its landscape.
