Breathing is basically divided into abdominal breathing, chest breathing and abdominal-chest complete breathing, as well as single nostril cleaning meridian breathing.

Abdominal breathing-breathing at the bottom of the lungs, only feeling the abdomen stirring and the chest relatively static.

Chest Breathing-Breathing with the upper and middle parts of the lungs, feeling that the chest is expanding and contracting, and the abdomen is relatively static.

Complete breathing-the upper, middle and lower parts of the lung are involved in breathing. Abdomen, chest and even the whole body have a feeling of ups and downs.

Single nostril cleaning meridian breathing

Practice: sit cross-legged, hold your knees with your left hand, put your middle finger and forefinger against your eyebrows, put your thumb and ring finger on both sides of your nose, put your thumb against your right nostril, and slowly do yoga breathing with your left nostril for five times. At this time, you should close your eyes, carefully experience the movement in your body, and inhale evenly and gently. When finished, release the thumb, press the left nostril with the ring finger, and slowly use the right nostril. Repeat round 5- 10.

Note: the time of inhalation and exhalation should be equal. Don't make a sound when breathing in and out of your nostrils. If you have rhinitis or cold, don't do this breathing exercise.
