expiration
abdominal respiration
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.
The key to abdominal breathing is: inhale and exhale as far as possible to reach the "limit", that is, you can no longer inhale and exhale; 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, when you have a headache, you can suddenly leave the ground when you breathe in one breath, 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.
