What causes leg cramps while sleeping

Some friends may suddenly wake up from leg cramps while sleeping. This situation is very common. Leg cramps while sleeping may be caused by external temperature stimulation, excessive fatigue and inability of muscles to relax, or calcium deficiency.

The most common causes of leg cramps are:

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, which can 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 Decreased estrogen levels and osteoporosis in elderly women can 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.

To prevent leg cramps, you should pay attention to the following points:

① Drive away the cold and keep warm.

②Pay attention to your sleeping posture.

⑧Do not walk or exercise for too long.

④ Participate in physical exercise appropriately ⑼

⑤ Supplement some vitamin E if necessary.

⑥ Appropriate calcium supplementation. Foods containing lactic acid and amino acids, such as dairy products and lean meat, can promote the dissolution of calcium salts and help absorption.
