First, one of the simplest ways to treat myopia is to gaze into the distance as far as possible to relax the eye muscles. However, in cities, factors such as industrial pollution and the heat island effect lead to higher levels of suspended particulate matter in the air and poorer visibility. In mountainous areas, especially at mountain summits, you can look into the far distance, relieving eye muscle fatigue.
Second, the vast expanses of primeval forests and grasslands in the mountains far surpass the green spaces and plants found in urban areas. Therefore, walking in the mountains helps improve lung ventilation, increase lung capacity, enhance pulmonary function, and also strengthens the heart's contracting ability.
Third, mountain trails are rugged and uneven, and traversing them helps improve the body’s balance, enhances limb coordination, and especially when walking on natural, non-step sections, it can thicken muscle fibers, develop muscles, and improve limb flexibility.
Fourth, the body's normal metabolism relies mainly on aerobic metabolism. Mountain climbing, especially at high altitudes, causes most of the body’s metabolism to switch to anaerobic due to thin air. Coupled with the high level of physical activity involved in mountain climbing and camping, and the fact that mountain meals often fail to meet the body’s caloric needs, it leads to substantial consumption of accumulated fat—especially around the waist and abdomen.
Fifth, during normal human metabolism, a harmful substance called free radicals is produced. These can damage cell membranes, dissolve normal cells, and cause tissue aging or even mutation. Negative oxygen ions can effectively bind with free radicals and expel them from the body. Data shows that the concentration of negative oxygen ions on city streets is only about 100 to 300 per unit, while in mountain forests it can reach tens of thousands. Therefore, hiking and camping in the mountains can effectively eliminate harmful free radicals and help delay aging.
Sixth, mountain climbing helps relieve psychological stress and regulate tension, improving both physiological and psychological states, restoring physical strength and energy, and enabling people to engage in learning and work with vigor. Mountain climbing exercises also refine one’s sentiment, maintain a healthy mindset, and fully harness individual initiative, creativity, and enthusiasm—thereby boosting self-confidence and values, allowing personality to develop healthily and harmoniously in a supportive environment. Additionally, it fosters a sense of unity, cooperation, and collectivism.
