Take a supine position or a comfortable sitting position, you can put one hand on your navel, relax your whole body, breathe naturally first, then inhale, and expand your abdomen to the maximum extent, so that your abdomen bulges and your chest remains motionless.

2. Call out points:

The abdomen naturally sinks inward toward the spine, and the chest remains motionless. Try to contract the abdomen inward and exhale all the exhaust gas from the lungs. When doing so, the diaphragm will naturally rise. Cycle back and forth, keep the rhythm of each breath consistent, and carefully experience the ups and downs of the abdomen.

3, the key to abdominal breathing:

Whether you inhale or exhale, you should try to reach the "limit" amount, that is, you can't inhale or breathe again. In the same way, the abdomen should contract and expand to the extreme, and it would be better if you went straight to Xiadantian every time you breathe.

Abdominal breathing is generally used for health care. Because the inhaled oxygen is two to three times more than normal, it can also be used to treat diseases in various parts of human internal organs. For example, if you have a headache, when you take a deep breath, your heel suddenly leaves the ground, forcing the gas to go straight to your head and then exhale. Of course, different rehabilitation treatments should be accompanied by drugs and carried out under the guidance of doctors.

Abdominal deep breathing is easy to learn. Standing, standing, sitting and lying down can be done at any time, but lying in bed is better. Lie on your back in bed, loosen your belt, relax your limbs, concentrate your thoughts and get rid of other thoughts. You can also say that you are in qigong state. Inhale slowly through the nose, tuck in the abdomen, keep 10 ~ 15 seconds for each breath, and then exhale slowly, breathing 4 times per minute.

The length of abdominal deep breathing is controlled by the individual, and it can also be combined with chest breathing, which is an alternate movement of the respiratory system. If you can persist in doing abdominal deep breathing every day for many years, you will receive the miraculous effect of "inadvertently inserting willow into the shade", strengthen your body and prolong your life.

Extended data:

Abdominal breathing is the most important and basic way of breathing in yoga. It is the basis of learning other breathing methods, which can be accomplished by increasing the activity of diaphragm and reducing the movement of chest.

Abdominal breathing means moving the diaphragm up and down. Because when inhaling, the diaphragm will drop and squeeze the organs below, so the stomach will expand, not the chest. Therefore, when exhaling, the diaphragm will rise higher than usual, so you can take a deep breath and spit out more carbon dioxide that is easy to stay at the bottom of the lung.
