Qi is everywhere, is it a cloud in the sky? Water is underground and wind is on the ground. Qi is the most basic substance that constitutes the earth's world, and everything is produced by the movement and change of Qi.
Qi is a component of the human body and the most basic substance to maintain human life activities, so life depends only on qi, which leads to life when gathered, and death when scattered.
1, Qi can promote the transportation and transformation of viscera, the generation and operation of blood, and the transportation and excretion of body fluid and water.
2. Qi has the function of warming. Qi is the source of maintaining human heat. Qi maintains body temperature by generating heat through movement changes. It warms viscera, meridians and other tissues and organs for normal physiological activities, such as warming blood, which coagulates when it is cold. If the warm function of qi is abnormal, it is afraid of cold and cold, and the limbs are not warm, which is easy to cause cold, dampness and turbidity.
3. Qi has a defensive function, protecting the skin and fighting against epidemics and evil spirits. Qi deficiency will weaken the defensive kinetic energy and reduce the immune ability, which is not only easy to get sick, but also difficult to recover after illness. When pathogenic factors are combined, their qi will be deficient.
4. Qi has the function of fixation to prevent the loss of blood and body fluids. Weakness of Qi will lead to the loss of liquid substances in the body, such as spontaneous sweating, polyuria, incontinence, drooling, nocturnal emission, qi deficiency leading to unstable fetal movement and abortion.
5. Qi has the functions of gasification and nutrition, promotes the metabolism and mutual transformation of essence, qi, blood and body fluid, and provides necessary nutrition for various organs. Part of it comes from the essence of cereal in the diet, and part comes from the fresh air inhaled through the lungs. The close relationship between human organs and tissues can be induced and transmitted through the movement of qi, thus reflecting all kinds of life information.
Although the above-mentioned qi has different functions of rising, warming, maintaining, consolidating, transforming, nourishing and regulating, it is indispensable in human life activities. They promote and coordinate with each other and maintain the normal life activities of human beings. Qi is constantly moving in the human body, spreading in organs such as zang-fu organs, meridians, etc., everywhere, rising, falling and coming in and out in the body, promoting and restricting each other, maintaining a coordinated state, and ensuring the smooth operation and harmonious balance of the human body. If human qi is abnormal, it will be a disease, but it will be life-threatening.
