I think it is necessary to talk to you about deep breathing exercise. From the perspective of modern medicine, deep breathing exercise itself is a healthy exercise, which can obviously improve health. Why does deep breathing have such a great effect? As we know, deep breathing strengthens the supply of oxygen, which plays a great role in strengthening the body and removing diseases in the process of metabolic exchange. Because slow and conscious deep breathing can increase the alkaline content in the body, at the same time, it can speed up the beating of the heart and blood circulation, and supply more oxygen to the body. The blood will transport oxygen and nutrients to the cells of the whole body to keep healthy. On the other hand, through deep breathing and sweating, the waste and toxins in the body are excreted, the acid content in the body is reduced, and the chemical components in the human body are kept in balance, so that the sub-health is separated.
From the perspective of Qigong, taking a deep breath after vomiting can promote the smooth flow of blood and lymph and restore the connection between nervous systems. Various nerve endings will be stimulated together, directly or indirectly stimulating the use of blood vessels, and muscles will also improve their nutrition because of the improvement of metabolism. Some chronic diseases or internal injuries will follow the normal function of the nervous system and can be cured without drugs.
So, what should you pay attention to in deep breathing exercise?
When you take a deep breath, try to relax your whole body muscles and breathe calmly, then stretch your hands and inhale deeply through your nose until you can't breathe any more. Then transport the inhaled air to the abdomen, hold your breath and adjust your breath for about a few seconds, and then it will be operated by the abdomen and spit out through the heart, trachea and throat.
It should be noted here that the time for holding your breath and adjusting your breath is about three to four seconds at first, and then gradually increases to about eight seconds. This process needs time and skill growth to be realized step by step. Deep breathing and exhalation can be divided into inhalation and exhalation, inhalation and exhalation, inhalation and exhalation, etc.
In a word, "hold your breath" and "take a deep breath" are not the same. Breathing and exhaling is a natural law of human beings, and deep breathing is extended according to its function. We try to improve this natural law and try to grasp the skills of heaven and earth to keep fit.
