If there is nothing wrong with your body, you may catch a cold when you sleep, such as turning on the air conditioner or blowing an electric fan when you sleep in summer, but there is no quilt on your legs. After a cold night, your calf is prone to cramps when the temperature is too low. If this is the case, the prevention method is simple. Don't let the fan and air conditioner blow on your legs, or cover yourself with a quilt to keep warm when you sleep.
Some people have cramps in their legs because of calcium deficiency. Among these people, middle-aged and elderly women account for the vast majority. Because after menopause, the secretion of estrogen in middle-aged and elderly women decreases, resulting in low blood calcium and insufficient calcium in the body, which leads to cramps. At this time, calcium tablets and vitamin D can be supplemented. Only when there is no calcium deficiency in the body can this situation be improved. ?
In addition, if there is too much physical labor that day, it is easy to cramp. For example, if you exercise too much, or walk a lot in a day and accumulate too much lactic acid in your muscles, your legs will cramp easily when you sleep. So if you exercise too much that day, you'd better do some stretching exercises after exercise. Simple stretching can prevent cramps. ?
There is also a situation that can easily lead to cramps, that is, sleeping in an incorrect posture. If you can't sleep in the right posture, it is likely to cause passive contraction of a certain muscle group, leading to cramps. Therefore, even if you are sleepy and tired again, you should set your posture before going to bed and find a comfortable sleeping position to make yourself worry-free all night. ?
If you are a person who often cramps, you should supplement more nutrition, such as eating more fresh fruits and vegetables and supplementing various vitamins and calcium. Only when the nutrition in the body is comprehensive and rich can the occurrence of cramps be reduced. In addition, besides fruits and vegetables, you can also drink more milk and eat animal liver, which is rich in calcium and vitamin D. It is much healthier to absorb nutrients from food than to eat calcium tablets directly.
