The biting cold wind in winter in Zhang Chengyu always makes people reluctant to go out. When the amount of exercise is greatly reduced, muscle strength tends to decrease, and the intestine becomes lazy because of insufficient muscle strength. In addition, when the weather is cold, the blood circulation of the human body is reduced, and intestinal peristalsis is not as active as when it is warm, and constipation is more likely to occur. Japanese acupuncturists recommend a way of walking that can promote intestinal peristalsis, move your knees and twist your waist when taking a bath, which will help improve the annoying constipation problem! Constipation is not necessarily a lack of dietary fiber, muscle weakness and insufficient exercise may also cause constipation. According to the health education materials of Zhenbi Hospital of Japanese Medical Association, constipation is particularly easy in winter, and many people will be constipated because of insufficient exercise and cold. Hiroyuki Kobayashi, a medical professor at Shuntian University in Japan, also believes that staying indoors often in winter will reduce the amount of activity and thus reduce gastrointestinal motility. It is suggested that moderate exercise can promote blood flow, activate parasympathetic nerves, help the body relax and help the intestinal tract run more smoothly. Japanese acupuncturist Lin Ruolisha said that at the end of each year, many people are very busy and eat too much, which leads to abnormal intestinal function and easily leads to constipation and gastrointestinal discomfort. Although the lack of dietary fiber is a well-known cause of constipation, modern women are mostly "cold constipation", which is common in women with too little muscle mass and insufficient exercise. Many people will aggravate constipation by eating too much lettuce, which will increase the burden on the stomach. Walking with heavy load and twisting the waist in the bath can help to improve constipation. If Lin suggests walking more than 6000 ~ 8000 steps every day, you can improve constipation by exercising your intestines. You can also do simple exercise at home, take a bath and twist your waist to help activate your intestines. Bears walk with palms and soles touching the ground, knees not touching the ground, and slowly move forward with different hands and feet 10 step, which can help to exercise trunk, abdominal muscles and iliopsoas muscles, help intestinal peristalsis and improve constipation. Twist your waist when taking a bath and take a bath with 40 degrees hot water. Hold the sides of the bathtub so that the ischium really touches the bottom of the bathtub. Then put your legs together and tilt your knees to both sides, and do 10 times left and right to help straighten the intestine, activate the intestine and promote defecation.
