There is a view in traditional Chinese medicine: healthy qi exists, and evil cannot be done. In other words, if the body is full of vitality, it is not afraid of pathogenic bacteria in the surrounding environment. I certainly agree with this, but I think it is necessary to explain to you that there are conditions: a person's righteousness has a certain limit. If there are too many germs invading from outside, or there are too many low-temperature events and toxic gases, it will also run out of vitality. Vitality is used to expel foreign bodies. If toxic substances such as formaldehyde and hydrogen sulfide produced by decomposition cannot be excreted in time, the potential difference of cells will be greatly reduced. As a result, it can't normally produce energy to supply the brain, and illness is inevitable. Only by keeping healthy with qi can we "keep healthy and not be evil". Keeping healthy with qi is an important aspect of the way of keeping healthy. There is no need to take nourishing qi and vitality as the foundation of life. People should pursue something, not expect it. If you can't expect it, it will hurt your health. There are many opportunities in the commodity society, but the factors of opportunity and luck are not equal. People ask them to do what they can, give up what they can, and cultivate their vitality with peace of mind, so that "righteousness exists in memory and evil cannot be done." People with strong desires are detrimental to their vitality, and health is even more impossible. Expanding the stomach and nourishing qi The human body relies on the stomach to digest and absorb nutrients, and it is very important to expand the stomach and nourish qi. Diet should be light, not too full, and the thickness of meat and vegetables should be reasonably matched and adjusted. Excessive diet, alcohol and tobacco will lead to insufficient stomach qi and insufficient qi and blood. Emotional depression and sentimentality will lead to endocrine disorders, which is contrary to the principle of "widening the stomach and nourishing qi" in traditional Chinese medicine. Chinese medicine believes that excessive anger will damage the lungs and blood stasis, while excessive euphoria will lead to scattered qi and blood, and thinking is too weak for the spleen and stomach. With the intensification of competition in modern society, we should prevent impetuousness. Be good at restraint, self-doubt, downplay gains and losses, and handle interpersonal relationships well. He who thinks is blessed by himself, and he who thinks is extremely difficult; Calm mind can balance yin and yang, harmonize six veins, eliminate diseases and prolong life. Long whistling to relieve qi is an important health preserving method of the ancients. Whistling can massage and stimulate the nose, throat, chest and abdomen, which can be seen from the singer's longevity. After dinner, taking a walk, or humming your favorite poems, or humming Beijing opera, or singing loudly, can relax your mood, eliminate distractions and achieve ecstasy. If you can keep your brain quiet for half an hour or an hour every day, you can give full play to the potential of brain cells, coordinate physiology and emotions, and reduce the consumption of heat energy. A quiet brain makes muscles easy to relax, and qi and blood run smoothly, reaching the realm of "peace of mind, getting older and stronger". It's good to spend some time watching green every day.
