1, eyes slightly closed, keep breathing naturally, that is, inhale and exhale as usual, don't deliberately deepen the force, just concentrate on inhaling and exhaling, concentrate on observing the inhaling and exhaling movements, be alert to breathing, and be clear from this dynamic. 2, breathing sometimes deep, sometimes shallow, it doesn't matter, just breathe naturally. The only thing is that when you take a deep breath, you must clearly know that these are deep breaths, when you take a shallow breath, you must know that these are shallow breaths, and so on.

abdominal respiration

1, sit cross-legged at will, with your eyes slightly closed. You can gently put your hands on your abdomen, with your thumb and forefinger around your navel to guide your attention to your abdomen. 2. When inhaling, I feel that my abdomen is slowly expanding like a balloon. With the expansion of the abdomen, the diaphragm drops. 3. When exhaling, if the deflated airbag in the abdomen sinks and is close to the spine, at the same time, the gas trapped in the body is exhausted as much as possible, and the diaphragm naturally rises with exhalation. Abdominal breathing is the most primitive breathing mode in human life. In the first few years after the baby is born, with the increase of age, it will gradually become shallow chest breathing, which is not suitable for abdominal breathing when full.

thoracic breathing

1. Keep the abdomen naturally flat, inhale evenly and slowly, and the abdomen will face the spine inward. 2. When taking a deep breath again, the ribs expand outward and upward. 3. Breath drives the spine to continue to go deep and upward, expanding the chest area, and finally the breath is concentrated on the top of the head. When exhaling, the whole body relaxes and the turbid gas is excreted.
