It was in the early 1980s that the Japanese Ministry of Agriculture,
Forestry and Fisheries coined the term "Shinrin-Yoku" (literally "Take
the atmosphere of the Forest"), to encourage citizens to take walks in
the forests.
In the 1990s, the matter was taken very seriously and Japanese
researchers carried out advanced studies on the physiological effects of
silvotherapy.
Many tests were carried out on volunteers and the results are exciting:
after only 40 minutes of walking, the participants saw their stress
level, heart rate and blood pressure decrease. .
