In summer, from Long Summer to beginning of autumn, there are six solar terms: Long Summer, Xiaoman, Miscanthus, Summer Solstice, Slight Summer and Great Summer. Huangdi Neijing said: "Xia San Moon ... heaven and earth are in harmony, and everything is flashy." This means that in the three-month midsummer, the yang in nature has gradually reached the point of prosperity. On the one hand, the sun is pushing down, on the other hand, the geothermal energy is rising. This intersection of heaven and earth has greatly promoted the "flash" of everything.
In fact, as early as more than 2,000 years ago, our ancestors "predicted" such a health knowledge to people: everything is glorious in summer, and the yang is abundant outside, so health-preserving people should pay attention to maintaining the yang to adapt to the environment where the yin is insufficient in nature at this time.
Keep in good health at the right time, and don't compete with nature.
We know that everything in the world has a constant law of motion and change. As far as seasons are concerned, there are four distinct seasons: spring, long summer, autumn harvest and winter storage. If people want to live a long and healthy life, they must follow this natural law, or conform to this "trend", that is, the idea of "the integration of man and nature at four seasons" as mentioned by Chinese medicine.
If you violate this law and insist on "competing" and "bravado" with nature, it will be human beings who suffer. Because, no matter how capable people are, they can't change the natural attributes of the human body. For example, although modern medicine and technology are developed, they still cannot change the natural laws of human birth, aging, illness and death.
Xia San month, the human body's metabolism is very strong. This is a good thing, but if you ignore the essentials of keeping in good health in summer, it may become a bad thing. Although the essence of the sun is abundant in summer, it is easy to leak out; Long days, short nights, easy to lack sleep; Sweating a lot, easy to dehydrate; The weather is too hot, which easily affects people's appetite; People are also prone to get sick because of greed. ...
Excessive heart fire leads to deficiency of both lung and kidney.
In summer, most people get sick immediately, so there is a saying that "the debt is quick in June". However, there is a disease that lurks until autumn, and if it continues into winter, it will be very serious-this is "heart disease". That is, Neijing said: "This summer's qi should be the way to grow up. On the contrary, it is sad, autumn is malaria, and winter is seriously ill. " It must be explained that the "heart disease" mentioned here does not refer to the "cardiovascular disease" in modern medicine, but refers to the mental illness related to "consciousness and emotion".
The "heart" mentioned in ancient books is actually equivalent to the "god" and "psychology" that people often say today. According to the "Five Elements Theory" of traditional Chinese medicine, summer is a season of vigorous fire (summer dominates the heart, and the heart is very vigorous in summer), soil phase (spleen and stomach are in a prosperous position), wood rest (liver is in a relatively static state), water confinement (kidney is easy to be deficient), and gold dies (lung is easy to be deficient).
When the heart is full of fire, fire can kill gold, so it is easy to cause lung (gold) deficiency; This is because the kidney water blocks the heart fire, and when the heart fire is very strong, the heart fire is easy to counterattack the kidney water, so the kidney water is easy to lose.
If the gas is smooth, it will be smooth, and if the gas is chaotic, it will be reversed.
Most people can easily accept the concept of preventing "lung deficiency and kidney deficiency" in summer, but they often take it lightly and think that the blooming "heart" should be maintained.
In ancient times, there was no air conditioning equipment, and when summer was hot and difficult, people's mood was particularly irritable; Modern people can use air conditioning in summer, but it is easy to feel uneasy on sunny days. Moreover, air conditioning is not everything. Only learning to adjust yourself is the best policy.
So, how to adjust yourself? Neijing says well: stay up late and get up early (to the effect that: stay up late to adapt to natural yin deficiency; Get up early to keep up with the sun's spirit. If you don't get enough sleep, you can take a nap to supplement it. If you are bored with a day, you won't be angry (to the effect that you won't be upset and lose your temper because you hate long days), so that Hua Ying can become a beautiful girl, so that you can vent your anger (to the effect that you should be full of energy, achieve the beauty that summer should have, and fully vent). If your love is outside, your feelings should be fully exposed, not hidden.
The beauty of this passage in Neijing is that "Qi" is talked about throughout. The key to health preservation in summer is to make people "lifeless", and "essence" should be fully and normally "vented" instead of "chaotic". Disturbed is "confused", that is, "qi goes against", which hurts the spirit.
The living conditions of modern people have been greatly improved. In summer, on the one hand, we can objectively use diet and daily life to keep healthy, on the other hand, we can't ignore subjective meditation. In summer, you might as well consciously do some relaxing activities: proper morning exercise, proper entertainment, proper summer break ... In short, when you enter Xia Zhishi, you should first cultivate your "mind". I still remember the famous saying of a great thinker: "A happy mood is better than ten doses of good medicine."
