Nourishing essence means maintaining kidney essence.
Traditional Chinese medicine believes that men should not "prematurely break the yang" or "indulge in sexual intercourse". The key for men to preserve sperm is to control sexual intercourse so as not to consume kidney essence; Men can also use diet to make sperm. Huangdi Neijing holds that "essence is born in the valley", and only by constantly transforming Shui Gu's subtlety can kidney essence be filled; Medicine is an important way for men to preserve and nourish sperm. Ye, a medical scientist in Qing Dynasty, pointed out that flesh-and-blood products, such as antler glue, bovine bone marrow, placenta hominis and swim bladder, are the best products for replenishing essence.
Yiqi Yiqi is the protection and help for Yang.
Yang Qi should first keep out the cold. "The cold winter season is also the gas that kills the rage", so men should pay attention to cold protection in winter, and only the invasion of cold-proof evil can protect the yang; In the warm season of spring and summer, we should also prevent excessive greed and coldness, so as not to damage the yang. "Lao Lao Heng Ji Yan Xi" once pointed out: "The cold in spring is not frozen, and the lower body is too warm, so the upper body shrinks slightly, so the food with warm yang can also protect qi and strengthen yang. In Suwen, it was pointed out that "sweetness diffuses into yang", so men can eat more food such as onions, ginger, garlic, peanuts and mutton.
Adjusting the mind "if you nourish your heart too much, you will cultivate your shape" plays an important role in health preservation.
Men should first pay attention to self-cultivation, get rid of bad hobbies, emotions and distractions, and not be disturbed by "prosperity", "elegance and beauty", "lust for profit" and "fame and fortune";
Secondly, men should carry out reasonable life care, not only to control sexual intercourse and adapt to the four seasons, but also to develop good living habits. A good rest can affect a man's expression. Su Wen pointed out: "Being alive is like an impact, but the air is floating";
In addition, the diet should be reasonable, and don't eat spicy and sticky food. Su Wen's theory of anger also pointed out: "The taste is too spicy, the bones and muscles are sluggish, and the spiritual center." Men focus on self-cultivation and heart-nourishing. "Calm and nothingness, the true qi comes from it, but peace of mind?" I am diligent, I am obedient, and I have whatever I want.
Only by realizing the harmony between god and nature can we promote the maintenance of essence, otherwise it will hurt essence and qi.
Modern medicine believes that a calm and happy mood can ensure that a large number of activities are coordinated with the activities of various organs and systems of the body, so that men are full of energy and greatly improve the efficiency of their physical and mental work, while positive emotions can enhance the body's immunity.
People with negative emotions often have abnormalities in their brains and nervous systems. For example, fear can promote adrenal gland secretion, respiration, heartbeat and pulse increase, and platelets will also increase, thus causing blood coagulation and leading to systemic diseases.
Obviously, this is basically consistent with the theory of "regulating the mind" in traditional Chinese medicine.
