Harm of long standing

The hazards of standing for a long time include increased plantar pressure, muscle fatigue and strain, increased spinal pressure, varicose veins of lower limbs, blood circulation disorders, etc. Details are as follows: 1. When standing for a long time, the weight of the body is all concentrated on the sole, and standing for a long time will produce great pressure on the sole, which may cause foot diseases such as plantar fasciitis. 2. Muscle fatigue and strain Keep standing posture for a long time, muscles will be in a state of continuous tension and contraction, resulting in muscle hypoxia and accumulation of metabolic waste, which in turn causes muscle soreness, cramps, stiffness and other phenomena. Long-term, it may also cause muscle strain and damage. 3. Increased spinal pressure Standing for a long time will make all parts of the spine withstand continuous pressure, resulting in spinal stress imbalance and soft tissue fatigue. This increase in pressure may cause physiological pain and soreness of neck, shoulder, waist, back and other spinal joints and large joints. In severe cases, it may even lead to disc bulging, lumbar muscle strain and other problems. 4, varicose veins of the lower limbs standing, the vertical distance between the heart and the lower limbs is long, the lower limb blood vessels need to bear additional pressure load. The vein lumen is thin, the ability to resist pressure load is poor, standing for a long time is easy to cause vein damage, and then cause varicose veins of the lower limbs. Varicose veins not only affect the appearance, but also may cause pain, swelling and other symptoms, and may even lead to thrombosis in severe cases. 5, blood circulation disorders Standing for a long time will slow down the blood flow rate of the lower limbs, affecting blood circulation. This may lead to ischemia and hypoxia in the distal tissues of the lower limbs, which may lead to a series of health problems. In addition, when standing for a long time, the heart needs more power to pump blood to all parts of the body, especially the lower limbs. This will increase the burden on the heart and heart rate, and reduce heart efficiency. Regular physical examinations are needed in life to detect and deal with health problems caused by standing for a long time.
