What is the reason for cramps in the thighs in hot summer?

(1) Cold stimulation of external environment, such as low room temperature in winter nights, too thin quilt when sleeping, or exposed legs and feet.

② Fatigue, sleep, lack of rest or excessive rest lead to the accumulation of local acid metabolites, which can all cause muscle spasm. Too long walking or exercise time, excessive fatigue of lower limbs or insufficient rest and sleep will lead to lactic acid accumulation. Sleep rest time is too long, blood circulation slows down and carbon dioxide accumulates.

③ Decreased estrogen and osteoporosis in elderly women will lead to decreased blood calcium level, increased muscle stress and frequent spasms.

4 Poor sleep posture, such as lying on your back for a long time, making the quilt press on the foot surface, or prone for a long time, making the foot surface close to the bed, forcing some muscles of the calf to be in an absolute relaxed state for a long time, resulting in "passive contracture" of the muscles.

5. 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.

6. High blood lipids. 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.

7. 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.
