Waist twisting exercise: Waist twisting in the morning can effectively prevent constipation. The waist and abdomen are located in the hinge position of the human body, which has a great influence on the upper and lower digestive tract. Proper lumbosacral activity can promote gastrointestinal peristalsis and secretion of digestive juice, and treat constipation. The specific method is: stand with your feet apart, shoulder width or slightly wider, your arms droop naturally and your eyes look straight ahead. Keep your upper body straight, your legs and knees straight, and don't bend. Send the waist to the left first, then turn clockwise forward, right and backward. The whole process should be slow. You should not move your shoulders or bend your knees. Turn slowly for 30-50 turns, and then turn counterclockwise for 30-50 turns. When you do the action, you should be slow and coherent, breathe naturally and relax. At first, you can turn left and right for dozens of laps, then gradually increase the number of laps, and finally extend it to 1 half an hour. It is best to turn around in the morning, have an empty stomach, and then drink a cup of warm water after finishing.
