Leg cramps are most common in middle-aged and elderly people. Some men also often have leg cramps. So, what are the causes of leg cramps? Poor sleeping posture For example, lying on your back for a long time with the quilt pressing on your feet, or lying on your stomach for a long time with your feet against the bed, will force certain calf muscles to be in an absolutely relaxed state for a long time, causing "passive contraction" of the muscles. Fatigue, lack of sleep, or too much rest Leading to the accumulation of local acidic metabolic products can cause muscle spasms. For example, walking or exercising for too long, causing excessive fatigue of the lower limbs or insufficient rest and sleep can cause lactic acid accumulation; sleeping too much and too long can slow down blood circulation and cause carbon dioxide accumulation. Cold stimulation from the external environment For example, in winter when the room temperature is low at night, the quilt you use when sleeping is too thin or your legs and feet are exposed outside the quilt. |
