What causes body cramps

A body cramp is a type of muscle spasm, which is a spontaneous tonic contraction of a muscle, and it usually occurs in the calves and toes. Many people suffer from cramps. Once certain parts of the body cramp, we will feel pain and find it difficult to move. Severe cramps can even cause temporary coma. So what causes cramps? Now let me explain to you what causes body cramps.

1. Cold stimulation from the external environment, such as low room temperature at night in winter, using a quilt that is too thin during sleep or exposing legs and feet outside the quilt.

2. Fatigue, lack of sleep, rest or excessive rest can lead to the accumulation of local acidic metabolic products and cause muscle spasms. Walking or exercising for too long, which causes excessive fatigue in the lower limbs, or lack of rest and sleep, can cause lactic acid accumulation. Sleeping and resting too much or too long can slow down blood circulation and cause carbon dioxide accumulation.

3. The decline of estrogen and osteoporosis in elderly women will cause low blood calcium levels, increased muscle irritability and frequent cramps.

4. Bad sleeping posture, such as 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, forcing certain calf muscles to be in an absolutely relaxed state for a long time, causing "passive contracture" of the muscles.

5. Excessive sweating. Long exercise time. You exercise a lot, sweat a lot, and don't replenish salt in time. A large amount of fluid and electrolytes are lost from the body. Accumulation of metabolic waste. Poor local blood circulation in muscles can also lead to cramps.

6. Calcium deficiency. During muscle contraction. Calcium ions play an important role. When the calcium ion concentration in the blood is too low, muscles become easily excited and cramp. Teenagers grow and develop rapidly and are easily deficient in calcium, which is why they often suffer from leg cramps.

Now everyone knows the causes of cramps, so in order to reduce the occurrence of cramps, preventive measures are essential. In cold conditions, we must know how to keep warm, pay attention to our sleeping posture, take appropriate calcium supplements and get more sun exposure. Finally, the editor wishes everyone good health.
