Forest health care mainly refers to all activities that use high-quality forest environment and green forest products to enhance physical fitness and prevent, alleviate and treat diseases. Forest recuperation originated in Germany in the 1940s. Based on the rich and colorful forest ecological landscape, high-quality oxygen-enriched forest environment and profound forest health culture, it is equipped with corresponding health care, leisure and medical service facilities to carry out forest leisure, vacation, recuperation, health care, old-age care and other service activities aimed at restoring physical and mental health and delaying life aging.

High concentration of negative oxygen ions, the forest factor in the forest, can play a very good health care role. Scientific research has confirmed that negative oxygen ions in the air, like vitamins in food, have a very important influence on the life activities of human beings and other creatures. They are known as "air vitamins", which can make people healthy and live longer, so they are also called "longevity elements". Negative oxygen ions can effectively eliminate free radicals in human body, while keeping human body fluids in a weak alkaline state. It can eliminate fatigue, enhance lung ventilation, improve immunity, assist in the treatment of common diseases of the elderly such as emphysema, hypertension, asthma, etc., and has a special effect of delaying aging. At present, the ecological negative ion technology of negative ion system and pollutant collection system can produce high concentration and small particle size ecological negative ions, which can be used for medical care in daily life.
