Why do you always have leg cramps? What causes leg cramps?

I believe everyone has experienced leg cramps. Generally, smoking once will impress you. That kind of pain is really unbearable for ordinary people. Because of leg cramps, I often roll in my arms at night. Most cramps are caused by sudden muscle excitement, which leads to sudden and asymptomatic muscle contraction and spasm, usually lasting for a few seconds, not more than one minute. There are many reasons for cramps, but most of them are related to our bad living habits. Let me tell you something about the causes and prevention of cramps.

1. Cold legs

Most people will have cramps when they sleep at night, often because the quilt is not properly covered and their legs are exposed to the cold, which leads to cramps in the calf muscles. Swimming in summer without warm-up exercise and suddenly jumping into the cold pool can also easily lead to cramps.

2. Poor blood circulation

Muscles contract and relax during exercise or action, and the process of contraction and relaxation always squeezes blood vessels. When you sleep, your body functions slow down and your blood slows down. Slow blood flow can't take away lactic acid from muscles and accumulate in blood vessels, which leads to poor blood circulation and stimulates muscles. Muscle spasms can form cramps.

3. Calcium deficiency

Calcium is one of the most important elements in human body. When our blood is short of calcium, our muscles will become excited and cramp, which will lead to cramps.

4. How to alleviate it

Eat more foods with high calcium content such as milk, eggs and meat. At ordinary times, we should also strengthen exercise and exercise muscles to make them stronger and more resistant. In order to prevent cramps during sleep, you can soak a hot foot before going to bed to relax leg muscles and speed up blood circulation. Cover the quilt when you sleep to prevent your legs from catching cold. When there are symptoms of leg cramps, massage the cramped parts quickly to speed up blood circulation and relieve the symptoms.

Cramp is a very common symptom. Don't panic when it happens. Paying more attention to exercise and reasonable living habits can reduce cramps.
