First, take a deep breath: first, slowly inhale through the nostrils to fill the lower part of the lungs with air. During inhalation, the abdomen will bulge slowly because the chest is lifted up and the diaphragm is lowered. Then continue to inhale, so that the upper part of the lungs is also filled with air. At this time, the ribs will be lifted and the chest will be enlarged. At this time, the ribs will be lifted and the chest will be enlarged. This process usually takes 5 seconds. Finally hold your breath for 5 seconds. After a period of practice, you can increase your breath holding time to 1 seconds or even more. After the lungs absorb enough oxygen, exhale slowly, and the ribs and sternum gradually return to their original positions. Pause for a second or two, then start from the beginning and repeat for 1 minutes. Practice for a long time can become a normal breathing method. ?

2. Static breathing method: Hold the thumb of the right hand on the right nostril, slowly take a deep breath through the left nostril, and consciously imagine that the air is flowing towards the forehead. When the air in the lungs is saturated, press the left nostril with the index finger and middle finger of the right hand and hold your breath for 1 seconds before exhaling. Then hold down the left nostril and start over. Do it five times on each side. ?

third, sleep breathing method: lie on the bed, put your hands flat on your sides, close your eyes and start to take a deep breath. Slowly raise your arms over your head, close to your ears, and touch the bed with your fingers. This process takes about 1 seconds, and the arms are restored at the same time, repeated 1 times. This method can also help you sleep peacefully. ?

fourth, exercise breathing method: actively increase the breathing volume when walking or jogging, breathe slowly and breathe quickly, and slowly enlarge the chest with inhalation when breathing slowly, and exhale quickly. Exercise not less than 2 times each time, but several times a day.
