In the early morning park, one can always find fitness enthusiasts banging their backs and arms against trees. Some people believe that rough and uneven bark can stimulate meridians and acupoints by hitting the tree with their body, achieving the effect of strengthening the body. However, this statement lacks scientific basis and poses serious safety risks, especially for the elderly, who may suffer serious consequences from blindly hitting trees for exercise. The risk of tree impact exercise is vascular damage in elderly people. The elasticity and fragility of blood vessels decrease, and tree impact may cause plaque shedding in blood vessels, leading to life-threatening diseases such as cerebral infarction and heart attack. Excessive impact force on musculoskeletal injuries can easily cause muscle strains, cervical spine injuries, and even fractures, especially in elderly people with osteoporosis and lumbar muscle strain, with a higher risk. Rhabdomyolysis refers to the rupture of skeletal muscles (rhabdomyosis) due to excessive compression, impact, or vigorous exercise, resulting in the release of large amounts of myoglobin, creatine kinase, and other substances from muscle cells into the bloodstream. May cause acute kidney injury, kidney failure, electrolyte imbalance, systemic inflammatory response, etc. Other risks include rough and uneven surface of trees, which may cause skin damage and increase the risk of infection upon impact. These exercises are suitable for our parents. Elderly people should follow the principles of science, safety, and moderation when exercising, and choose a suitable exercise method for themselves. For example, walking is simple and easy to do, which can help improve cardiovascular function. Tai Chi movements are soothing and can enhance balance and flexibility. Swimming has minimal impact on joints and is suitable for elderly people with joint problems. Scientific exercise safety first. Before exercising, it is best for elderly people to consult a doctor, especially those with underlying diseases, and choose suitable exercise programs based on their own health conditions. In addition, it is important to choose a safe and comfortable sports environment to avoid accidents; The intensity of exercise should be gradual and measured, avoiding excessive fatigue. In summary, tree hitting exercise is not a scientific way of health preservation. Elderly people should choose safe and effective exercise methods to achieve the goal of strengthening their bodies.
