In the dead of winter, many middle-aged and elderly people often sleep until midnight, which is prone to leg cramps. What causes leg cramps? The causes of cramps are complicated, and the common ones are as follows:

First, arteriosclerosis. With the increase of age and arteriosclerosis, there will be obstacles in blood supply. Once the climate changes and the weather gets cold, this obstacle will become more prominent, so hands and feet will cramp. This is the main reason why middle-aged and elderly people have leg cramps at midnight.

2. Hyperlipidemia. Because of high blood fat, high blood viscosity and slow blood flow, it is easier to get leg cramps in the middle of the night.

3. Calcium deficiency. Calcium deficiency is also a common cause. Especially postmenopausal women. Once the body lacks calcium, not only middle-aged and elderly people, but also young people will cramp; Not only at night, but also during the day.

4. Heart disease. Especially people with cardiac insufficiency will aggravate hand and foot cramps. Because the muscle nutrition of the whole body depends on the blood supply of the heart, the heart function is not complete, and the blood supply will of course be worse.
