There is a substance in the forest that is extremely beneficial to human health-negative ions. According to the measurement, there are only 40 to 50 negative ions per cubic centimeter in urban houses, 100 to 200 in tree-lined places and 10000 to 50000 in forests. Green plants in the forest can absorb carbon dioxide, release oxygen and absorb harmful gases through photosynthesis: a linden tree can absorb 16 kg of carbon dioxide a day, poplar, willow, locust tree and other 150 hectares of broad-leaved forest can produce 100 tons of oxygen a day, and 0.4 hectares of forest belt can absorb and assimilate/kloc-a year.
Forest has a special function of promoting human physical and mental health, and it is favored by people more and more. However, at the present stage in our country, the products of forest serving human beings have a single function, and basically stay in sightseeing such as eating, living and playing. The significance and well-being of forests to human beings are far from being explored. For example, rehabilitation, health care, recuperation, old-age care, popular science education and Chinese health culture have not yet formed personalized and integrated service products with the help of forest environment.
Internationally, Germany, the United States, Japan, the Netherlands, Britain, Norway, South Korea and other countries have practiced and carried out various rehabilitation treatments in different forms and to varying degrees, and achieved certain results. After the implementation of forest restoration project in Germany, the total national medical expenses decreased by 30%, which means that the national health index rose by 30% as a whole.
Forest health care is people-oriented, forest-based and health and nutrition-oriented. It fully embodies the development concept of "innovation, coordination, green, openness and sharing". Forest health care is a new format formed by the integration and extension of forestry, tourism, health services and other related industries. It is a new model promoted by forestry reform and an important content of promoting supply-side structural reform and strengthening green supply. 2. Forest health care refers to forest leisure, vacation, recuperation, health care, old-age care and other activities with colorful forest landscape, refreshing forest air environment, healthy and safe forest food and rich ecological culture as the main resources and support, and equipped with corresponding health care and leisure facilities. 3. Forest health care has a very effective health care effect on human health, and has the effect of "five educations": body, mind, temperament, wisdom and morality. When the city is plagued by smog and human life is destroyed by polluted air, more and more people yearn for the "lung of the earth"-the shelter of the forest, so forest health comes into being.
