What is the reason for calf cramps at night

Many people experience sudden calf cramps while sleeping at night. Sudden calf cramps can cause temporary pain and affect sleep quality, so everyone should pay attention to the problem of calf cramps at night. The quality of sleep at night can affect the next day's work and study status. Many people will ask, how can I prevent my calf cramps if I don’t know the reason? Next, I will explain to you the reasons for calf cramps at night.

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. Muscles contract too quickly and continuously. During strenuous exercise. The whole body is in a state of tension and the leg muscles contract too quickly. If the relaxation time is too short, the local metabolic product lactic acid will increase, and muscle contraction and relaxation will be difficult to coordinate, thus causing calf muscle cramps.

6. 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.

7. Excessive fatigue. The calf muscles are most susceptible to fatigue when traveling long distances, climbing mountains, or climbing heights. Because every time I climb high. The whole body weight is supported by one foot. The strength required for the muscles of this leg to lift the foot will be six times the human body weight. When it is fatigued to a certain extent, cramps will occur.

8. 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.

I hope that after reading my explanation, you can get effective help and solve the problem based on the cause. But sometimes it happens too frequently, such as cramps every day or every other day. The editor recommends that you go to the hospital to see a doctor as soon as possible to be safer. Finally, I wish you all a good sleep and a good spirit the next day.
