With the development of human civilization and the rapid advance of science and technology, people are liberated from heavy manual labor. More and more leisure time, so to adjust the body and mind, restore health, entertainment and learning for the main purpose of tourism is more and more popular. "Return to nature", "green awakening", "forest tourism", "forest bathing" and so on have developed rapidly. In forest tourism, a form of tourism aimed at hygiene, health care and recuperation is quietly rising. The main performance is forest short-term vacation, forest sanatorium and so on. In foreign countries such as Germany, forest environmental health law (climate, forest, topography and mountain spring utilization) is a natural health care law. In the former Soviet Union, findor science believed that the sterilization and purification function of forests had the effect of refreshing and calming people. The French believe that charged anions in forests have a great effect on human health. People in Europe and the United States believe that walking on the earth path between trees can regulate the innate rhythm of human life and make people refreshed and so on. Since ancient times, China has clearly recognized the value of forests for recuperation, medicine, hygiene and health care. In fact, the seclusion behavior of the refined scholars in The Qin and Han Dynasties is a kind of psychological treatment, which can soothe people's psychological trauma through the psychological treatment of mountains, rivers and forests. Li Zizhen's Compendium of Materia Medica is actually a complete collection of forest medicines. In all dynasties, the royal Pavilion was built in places with beautiful scenery and dense forests, which was to make use of the beautiful environmental quality of forests to adjust body and mind, restore physical strength and health. Modern scenic spots such as Lushan, national forest park such as Zhangjiajie, from the beginning of the construction, pay attention to the forest recuperation and health care function, planning and construction of special recuperation function area.

The forest climate formed by the combination of forest and landform is adapted to human survival by such climatic characteristics as low temperature, small temperature difference between day and night, high humidity, more rainfall within the region, and more clouds. Archaeological materials have proved that human's long childhood is spent in the forest. The existence of forests can produce a large amount of oxygen which is necessary for human survival and effectively reduce the harm of solar radiation and ultraviolet rays to human health. According to the census data, most of the long-lived elderly people and long-lived areas in China are mostly distributed in forest areas with beautiful environment and less pollution. A prominent example of this is the Landes forest in France, where the average life expectancy of residents has increased after the creation of coastal pine forests. While the increase in longevity is inevitable, it is so sudden that it is widely assumed to be a direct effect of forests. Therefore, some data show that as long as you walk or stay within 100 m of the forest, you can really enjoy the forest air, recuperate physically and mentally, often go to the forest for a walk, can prolong your life.
