How to breathe

breathing

It is the process by which the air travels in and out of the lungs through the respiratory system in the human body, and includes the processes of inhalation and exhalation. In the process of inhalation to get oxygen from the air, which means that the body needs oxygen to release energy through the process of cellular respiration, , And remove the effluent dioxide by exhale. Exhalation contains 100% relative humidity, and is one of the physiological processes to maintain the life required for all living organisms.

It is one of the important processes involving the movement of blood through the circulation of blood; where the exchange of gases in the alveoli pulmonary by the negative spread of gases between the gas and the blood in the capillaries in the lung, it should be noted that the air we breathe consists of 78.04% nitrogen , 21% oxygen, and 0.96% argon.

Breathing control

Breathing is one of a few body functions that can be controlled through conscious and unconscious process. Consciousness depends on observation by the person himself, through the use of various forms of meditation, especially in yoga, pranayama, swimming, fitness , While talking to others that rely on it mainly; where man needs to talk during the control in the early stages and in line with life, and can control the human breathing through the method of Buteyko, and alternative natural therapy, which proposes the use of breathing exercises, A person can control his breathing through unconscious control through specialized centers in the brain that regulate them automatically according to the needs of the body.

The state of increasing levels of carbon dioxide in the blood, which helps the oxide to interact with water in the blood; to produce carbonic acid, and lactic acid, which reduce the pH in the exercise, and this stimulates chemical receptors in carotid bodies, And the center of respiration in the rectum to send more nerve impulses to the center of the brain in the rectum, and the brain, which in turn send nerve impulses through the nerve fibers to the chest, and from the diaphragm.

It often happens that the human after exercising something tired is the process of exhaustion, which leads to a reduction in the proportion of CO2; so that it is lower than normal levels, in addition to reducing blood and oxygen in vital organs; because of the constriction of the vessels caused by the CO2, And the presence of very low oxygen levels, especially in the brain area.
