mountaineering and camping activities have great benefits to human body. From a medical point of view, it has great benefits to human vision, heart and lung function, limb coordination ability, consumption of excess fat in the body, delaying human aging and other five aspects have direct benefits.
     One of the simplest ways to treat myopia is to look at the distance and relax the eye muscles. However, due to factors such as industrial pollution and heat island effect in cities, there are many suspended particles in the air and poor visibility. In the wild, especially on the top of the mountain, it can make your eyes look infinitely far and relieve the fatigue of eye muscles.
     Second, the area of primary forest and grassland in the mountain is far from comparable to that of green land flowers and plants in the city. Therefore, walking in the mountains is very beneficial for improving lung ventilation, increasing lung capacity and improving lung function, and at the same time, it can also enhance the contractility of the heart.
     Third, the mountain road is bumpy, and walking through it is beneficial to improving the balance function of human body and enhancing the coordination ability of limbs, especially walking on non-step sections without artificial modification, it can thicken human muscle fibers, develop muscles and enhance limb flexibility.
    4. Sugar metabolism in people's daily body belongs to aerobic metabolism. Mountaineering activities, especially climbing mountains, are converted into anaerobic metabolism due to thin air, and the amount of exercise in mountaineering and camping activities is relatively large, picnics in the mountains are often difficult to meet the heat demand in the body. Therefore, it can consume a large amount of fat tissue accumulated in the body, especially the fat tissue in the waist and abdomen.
     Five, the normal metabolism of human body will produce a harmful substance called free radical, which can destroy the cell membrane of human body, dissolve the normal cells of human body, and cause the aging and even mutation of human tissues. However, oxygen anion can effectively combine with free radicals to discharge them out of the body. According to relevant data, the unit content of oxygen anion in urban streets is only 100 to 300, while that in mountain forests can reach tens of thousands. Therefore, walking camping in the mountains can effectively eliminate harmful free radicals, which is beneficial to delaying aging.
