Between heaven and earth, in the universe, all life activities are closely related to nature, and nature (big universe, macro whole) and people (small universe, micro individual) are mutual induction, interaction and reflection. Climate change in natural seasons has many effects on human body, such as emotional changes, regional differences, circadian rhythm, seasonal laws, dietary preferences and so on. # Cold # # Wet #

Wind, cold, heat, dampness, dryness and fire refer to six natural normal climates, which are called "six qi" by Chinese medicine. These normal climate changes are the natural conditions for the growth of everything and the survival of mankind. However, when the climate change is abnormal, the human body's healthy qi is insufficient, and the resistance is reduced, so that it cannot adapt to this climate change, the "six qi" becomes a pathogenic factor, which in turn leads to diseases in the human body. At this time, "six qi" is called "six yin". Traditional Chinese medicine believes that cold evil is one of the "six evils" When the temperature is low or suddenly drops, the human body is not cold and warm enough, and it is easy to catch cold and cause diseases.

Pathogenesis caused by cold pathogen is manifested in symptoms.

It is easy to hurt yang, stagnate and attract.

Because cold is yin evil, yin cold is excessive, and yang spirit is not enough to drive away cold evil, but it is injured by cold evil. The yang of human body is damaged, so it can't be warm, and there is obvious cold phenomenon in the whole body or part. Cold pathogen damages muscles and skin, blocks yang circulation on body surface, and causes sneezing, runny nose, headache, chills and even fever, which is called typhoid fever. Cold pathogen directly damages the meridians of zang-fu organs and yang, which is called moderate cold, such as vomiting and diarrhea, abdominal cold and abdominal pain when it hurts the spleen and stomach; If the lung is injured, cough and asthma will occur, and white foam-like sputum will be coughed up; If the kidney is injured, there will be more white urine and cold pain in the back; If the heart is injured, there will be cold hands and feet, listlessness and rapid pulse.

Stagnation means that coagulation is blocked and blocked. The normal operation of qi, blood and body fluid depends on the warmth and promotion of yang, so as to be unimpeded. Cold pathogen will make human qi and blood run poorly and the meridians become impassable. For example, cold pathogen hurts skin and muscles, which is manifested as head and body joint pain; If cold pathogen injures viscera, cyanosis of labial nail, cold pain in chest and abdomen or colic can be seen.

That is, contraction and traction. Similar to heat expansion and cold contraction, the meridians, bones and muscles of the human body will contract and shorten when they are attacked by cold pathogens, which is characterized by unfavorable joint flexion and extension, reduced activity and pain.

Cold is the main gas in winter, and cold diseases often occur in winter, but in winter, we have the function of indoor heating, wearing thick clothes and hats and scarves for outdoor activities, and our bodies also have the function of self-protection. Skin pores are closed, sweating is less, and the evil of yin and cold is less. In summer, air convection is strong, especially in mountainous areas, which is prone to extreme weather such as strong wind, heavy rain and hail. Moreover, human muscles are sore and often sweat, which is conducive to heat dissipation and cooling. If you enjoy the cold too much and eat too much cold food at this time, it will bring more opportunities for the evil of yin and cold to invade the human body.

Everything in nature needs the sun. In summer, there is plenty of sunshine and a warm climate. Animals and plants are highly mobile and grow rapidly. In winter, it is freezing, plants will wither and animals will hibernate. People's life activities also need yang. Yang is the motive force of human body's material metabolism and physiological activities, and the normal operation, work, exercise, study, disease rehabilitation, wound repair and other life activities need to consume Yang. The stronger the yang is, the stronger the human body is, full of spirit and quick thinking. Without yang, people are prone to fatigue, illness, listlessness and weakness in speaking and walking. When the yang is completely exhausted, people will die.

Therefore, it is very important to nourish yang in summer, protect the yang of human body and effectively avoid feeling cold in summer. In daily life, you should stay up later than in winter, but you can't stay up late, because from 23: 00 in the evening to 1 in the morning, that is, at midnight, it is the time when yin and yang of the human body meet, and it is also the time when yin is the most abundant and yang is the weakest in a day. Staying up late at this time will greatly dissipate the human body's yang, and daytime sleep can't supplement the lost yang. Get up early, take a walk in a wide place after getting up, or blend in with nature, climb mountains and enjoy flowers and swim around the lake, and wear loose clothes to prevent your body from being bound. The temperature difference between morning and evening in the north is large, and there are many thunderstorms. Weak children and the elderly should increase or decrease their clothes in time according to the cold and warm weather. Modern people have great work intensity and pressure. Taking advantage of the warm climate, we can increase outdoor activities in our busy life to get more sunshine and fresh air, which can exercise the respiratory and circulatory system, enhance cardiopulmonary function, promote blood circulation, adjust our mood and improve our sleep state. If you do strenuous exercise such as running, it is best to do it in the morning. Chinese medicine says that when the sun rises during the day, the yang is born. At this time, our movement is in line with nature; At night, the sun goes down and the soul of the sun goes in. If you exercise vigorously and sweat profusely, you will dissipate the essence of the sun. If you must exercise at night, you should go for a walk.

In summer, we should also change some living habits that hurt the sun's spirit. For example, blowing an electric fan can't directly affect people's health and can't blow an electric fan for too long; The air conditioner can't be adjusted too low and can't sit near the air outlet; It is not advisable to stay in the hospital for too long at night; Do not drink cold beer and drinks after strenuous exercise; Do not wash your hair with cold water after strenuous exercise; Can't eat the food taken out of the refrigerator directly; Don't eat too much ice cream.

When the temperature is high in summer, people's appetite is poor, so they can eat light food and eat more fruits and vegetables, such as cucumber, tomato, bitter gourd, wax gourd and watermelon. Drink more warm water, or drink mung bean soup, melon and barley soup to clear away heat and relieve summer heat. Eat less spicy and greasy products, such as beef and mutton, barbecue, hot pot and pepper. If you are eager to be cool, eat too much cold food, or catch cold in the rain, you will have cold deficiency in your stomach, fatigue, emaciation, abdominal pain and diarrhea. You can eat ginger to warm your stomach, warm the middle and dispel cold, and relieve symptoms.

Patients with chronic diseases can be treated in winter and summer, because the human body is connected with the external yang in summer. Some diseases prone to occur in winter, such as chilblain, asthma and rhinitis, can be treated by oral administration of traditional Chinese medicine, external application of acupoint application or moxibustion at Guanyuan, Shenque, Zusanli and Shenshu points. You can also massage your back at home, because there are Du Meridians on your back, and there are important acupoints such as Dazhui, Mingmen and Shenshu on the meridians. Stimulating these acupoints can strengthen yang, promote blood circulation and dredge collaterals, regulate the function of viscera, and make people healthy and live longer.

Don't take too much bitter, cold and heat-clearing drugs at will. If you consciously get angry and have constipation, you often take Sanhuang tablets and soak in water for a long time to drink cold drugs such as honeysuckle, dandelion and rhubarb, which will have short-term effects and hurt Yangyang. In particular, most patients with chronic diseases belong to yang deficiency type. If you are angry, it is also cold inside and hot outside. According to Huangdi Neijing, "all cold is kidney". Kidney yang is the root of Yangyang deficiency.
