Is using Douyin to lose weight harmful to the body

Using Douyin to lose weight may cause damage to the body, and long-term high-frequency vibration may lead to joint damage, visceral displacement, and other problems.

Douyin machines passively stimulate muscle contraction through high-frequency vibration, which may produce slight heat consumption in the short term, but cannot replace active exercise. During the vibration process, weight-bearing areas such as the lumbar spine and knee joints need to repeatedly withstand impacts, which may accelerate cartilage wear and induce chronic pain. Some users may experience vestibular dysfunction symptoms such as dizziness and nausea, which are related to vibration frequencies exceeding the body's tolerance threshold. Internal organs may experience positional displacement during continuous vibration, especially in individuals with relaxed abdominal walls who are at higher risk.

Special populations need to be particularly vigilant. Osteoporosis patients are prone to fractures caused by vibration, pregnant women may experience uterine contractions, and cardiovascular disease patients may increase heart load. The promotion of "local vibration fat burning" by some merchants lacks scientific basis, and fat decomposition requires systemic metabolic involvement. The weight loss effect often comes from brief dehydration after vibration, and the body weight tends to rebound after stopping use. Scientific weight loss should be combined with dietary management and active exercise. Adults should engage in 150-300 minutes of moderate intensity aerobic exercise per week. If vibration equipment is required, it is recommended to choose professional rehabilitation equipment with an amplitude of less than 10mm and a frequency of less than 20Hz. The single use should not exceed 15 minutes, and the weekly use should not exceed 3 times. Stop immediately if symptoms such as joint pain or palpitations occur, and seek medical attention if necessary to assess the extent of motor system damage. Individuals with a larger body weight should consult a rehabilitation physician before exercising and develop a step-by-step training plan.
