Why are there 20 days in the middle, 10 days? (Cold knowledge) Article 2? The dog days, which appear between Xiaoshu and beginning of autumn, are the days with the highest temperature, humidity and sultry weather in a year. V means latent. Crouching in the dog days means that evil spirits crouch. The so-called six evils (wind, cold, heat, dampness, dryness and fire) are summer evil. The so-called dog days refer to the dog days of the lunar calendar, which is the hottest period of the year.

? The dog days appear in hot summer and early autumn, which is the hottest and muggy day of the year. The so-called dog days refer to the dog days of the lunar calendar, which is the hottest period of the year. It can be understood that squatting means it is too hot to move. But the dog days are called dog days because there are also many cold factors. The dog days are the hottest thirty or forty days in a year in the Central Plains. The dog days are calculated according to the lunar calendar, between the middle and late July and the early August of the solar calendar.

? The length of accommodation is not fixed every year, and the length of accommodation is also different. It needs to be calculated by consulting the almanac. The lodging date can be simply expressed by a four-character formula from summer to the third Geng day in the future, that is, initial lodging 10 day, intermediate lodging 10 day or 20 days, and final lodging 10 day. In ancient China, the trunk and branch calendars were popular, and 60 groups of different names were used to record dates with 10 heavenly stems and 12 earthly branches, which were recycled. The day with the word "Geng" is called "Geng Day". Gengri's Geng character is the seventh word in 10 days, which is repeated every 10 days. Starting from the summer solstice, according to the date of trunk, the third Geng day is the first, the fourth Geng day is the middle, and the 1 th Geng day after beginning of autumn is the last. When there are four Geng days between the summer solstice and the beginning of autumn, the middle part is 10 days, and when there are five Geng days, the middle part is 20 days. It seems that the emergence of Gengri will affect the length of the first half sooner or later, so there will be 30 days in some years and 40 days in some years.

? Chinese medicine believes that summer dampness is suitable for nourishing the diet in dog days. In hot summer, people like cold drinks and drink plenty of water, so that moisture invades the human body, while external moisture enters the body, making water wet and invigorating the spleen, lifting the spleen and stomach, causing digestive dysfunction, stagnant water and loss of appetite. Dampness in summer is very harmful to the spleen, and bitter food has the effect of purging dryness, so it is not advisable to eat more, so it is advisable to eat more sweet and cold or sweet and cold in daily diet. And summer returns to the heart, but the heart likes cold and should be sour, so eat more acidic food in summer.

? For example, you can often eat some wheat products, such as plums, peaches, olives, pineapples, celery and so on. Traditional Chinese medicine pays attention to the unity of heaven and man and the complementarity of yin and yang. Therefore, in summer, people should eat more sour and sweet food and try not to eat spicy and warm food. It is also necessary to avoid eating too many cold drinks, which will harm the healthy qi in the human body and induce diseases. In cooking, cold salad and stir-fry are the best ways to eat in summer, which can retain the nutrition of vegetables to the greatest extent; With proper amount of vinegar, sauce, onion, ginger, garlic and mustard, it can promote appetite and digestion, inhibit bacteria, reduce blood fat and regulate blood pressure.

? Watermelon, bitter gourd, wax gourd, cucumber, towel gourd, tomato and other melons and eggplant fruits and vegetables have diuretic and hydrating effects, and are the first choice for summer food. In addition, attention should be paid to increasing nutrition in sleep diet. It is advisable to digest food easily, eat less greasy and spicy food, drink less and smoke less. In addition, sweating in summer will cause a large loss of salt, which will reduce the chloride ion reserve necessary for the formation of gastric acid in the blood, thus affecting the formation of hydrochloric acid in gastric juice, which is not conducive to the absorption of iron and calcium, so it is necessary to replenish water and salt in time. Water-replenishing soup tea beverage is a good choice. Soup contains a lot of water and organic salts such as sodium, potassium and magnesium, and tea can refresh the mind and relieve fatigue.

? But these soups and teas can relieve summer heat best when they are drunk hot, because warm tea can reduce the body surface temperature by 1 ~ 2℃ by relaxing sweat glands, and the effect of relieving summer heat is far better than that of Leng Cha.

? Common sense of heatstroke prevention

? The summer heat is coming. In recent days, the number of patients with cold, fever, headache, gastrointestinal discomfort and upper respiratory tract infection in hospitals has gradually increased, and some elderly people have also induced cardiovascular and cerebrovascular diseases. How to prevent heatstroke and cool down? In this hospital, Chinese medicine experts provide some summer heatstroke prevention tips to help you spend the summer:

? First of all, strenuous outdoor and daytime activities such as mountain climbing are not recommended in summer. It is recommended to choose sports activities such as swimming and jogging in the morning and evening.

? Second, drink more boiled water and drink water regularly. Don't wait until you are thirsty. It is not advisable to binge drink after thirst. Drink less fruit juice, soda and other drinks, which contain more saccharin and electrolyte. Drinking too much will cause bad stimulation to the gastrointestinal tract and affect digestion and appetite.

? Third, it is not advisable to drink too much. In summer, human body is easily affected by temperature, and excessive damp heat is the cause of skin sores, carbuncle and toxic swelling. If you drink a lot of white wine, it will contribute to dryness and dampness, which is tantamount to adding fuel to the fire.

? Fourth, the diet should not be too light. In summer, people have long activities, sweat a lot and consume a lot. They should eat more nutritious foods such as chicken, duck, lean meat, fish and eggs to meet the needs of human metabolism. Seasonal vegetables in summer, such as lettuce, cucumber and tomato, have high water content. Fresh fruits, such as peaches, apricots, watermelons and melons, have a water content of 80-90% and can be used to replenish water.

? Fifth, the nap time should not be too long. If the nap time is too long, the central nervous system will deepen the inhibition, the cerebral blood flow will be relatively reduced, and the metabolic process will slow down, leading to discomfort after waking up and more sleepiness.

? Sixth, avoid rapid cooling after heating. In hot summer, when people go out or come back from work, they like to either turn on the electric fan or take a cold bath immediately, which will make the pores of the whole body close quickly, but the heat in the body is difficult to dissipate, and it will also cause insufficient blood supply to the brain due to the rapid contraction of blood vessels in the brain, which makes people dizzy.

? Seven, air conditioning indoor and outdoor temperature difference should not be too big. The temperature difference between indoor and outdoor air conditioners should not exceed 5 degrees. Even if the weather is hot again, the indoor temperature of the air conditioner should not be lower than 24 degrees.

? Eight, should not wear metal jewelry. Some metals in metal ornaments are contaminated by sweat, and the skin may be red or itchy, which may easily lead to contact dermatitis.

? 9. Remember to prepare sunscreen equipment when you go out in summer. It is best not to walk in the hot sun from 10 to 4 pm. If you must go out at this time, you must take good protection, such as umbrella, sun hat and sunglasses, and it is best to apply sunscreen.

? Ten, daily life should be regular, do not often stay up late, to ensure adequate sleep is also an effective measure to prevent heatstroke. Be careful not to lie under the air conditioner outlet and electric fan when sleeping.

? Eleven, go out to carry heatstroke prevention and cooling drugs, such as ten drops of water, Ren Dan, essential oil, etc. In case of emergency.
