In recent years, some elderly people are keen on "hitting trees for exercise", believing that by hitting trees, they can stimulate meridians and acupuncture points to achieve the effect of strengthening the body. Experts suggest that the "tree collision exercise" lacks scientific basis and has potential safety hazards, so it should not be blindly carried out.

"The elasticity of blood vessels in the elderly decreases, the fragility increases, and hitting the tree may lead to the shedding of plaque in the blood vessels, causing life-threatening diseases such as cerebral infarction and myocardial infarction." Chen Lixia, chief physician of the Department of Rehabilitation Medicine at Peking Union Medical College Hospital, said that excessive impact force can also easily cause muscle strain, cervical spine injury, and even fractures, especially for the elderly with osteoporosis and lumbar muscle strain, the risk is higher. In addition, the surface of the tree is rough and uneven, and impacts can cause skin breakdown, increasing the risk of infection.

Shi Mingnan, a junior therapist in the Department of Rehabilitation Medicine of Peking Union Medical College Hospital, suggested that the elderly should follow the principles of science, safety and moderation in exercising, and choose the exercise methods that suit them, such as walking, tai chi, swimming, etc., step by step, do what they can, and avoid excessive fatigue. You can also consult your doctor before exercising to choose the right exercise program based on your health condition. According to Xinhua News Agency
