The time of accommodation is not fixed every year, and the length of accommodation is also different. You need to check the almanac to calculate it. Simply put, we can use the formula of "Xia San Geng" to express the lodging date, that is, from the third Geng day in Xia Hou, the initial lodging is 10 day, the intermediate lodging is 10 day or 20 days, and the final lodging is 10 day. In ancient China, the "trunk-branch calendar" was 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". The word "Geng" in Geng Day is the seventh word in "A, B, C, D, E, Ji, G, Xin, Ren, Gui" 10 day, and it is repeated every 10 day. 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. So some years will be 30 days and some years will be 40 days.

The so-called "dog days" refer to the first, middle and last three Geng days, and their specific dates are calculated according to the ancient China dry branch method.

At this stage, the human body relaxes and the meridians and blood circulate, which is conducive to the penetration and absorption of drugs. Gengri is also related to lung gold (Gengri is gold, belonging to the large intestine, and the large intestine and the lung are both exterior and interior), which is the best opportunity to dispel potential cold pathogens by warming the lungs with yang. In addition, the acupoints of bladder meridian and Du meridian, which have the functions of warming meridians, dispelling cold, resolving phlegm and relieving asthma, are carefully selected for application. They complement each other and help to strengthen the body resistance and eliminate pathogens, so they can play a role in preventing and treating diseases.

1, it is not advisable to binge drink after exercise. It's hot in the dog days, so people should not drink a lot of white water after exercising or sweating heavily. They should supplement some light salt (sugar) water appropriately, because too much salt is lost in the body after sweating heavily. If salt is not replenished in time, the ratio of water to salt in the body will be seriously unbalanced, leading to metabolic disorder.

2, it is not appropriate to drink too much. In summer, many people like to eat supper and drink a lot when they eat supper. 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.

5. Wet exercise: "Life lies in exercise", but people who are old and weak and usually lack exercise should never exercise vigorously, otherwise it will be harmful. It is known all over the world that the best exercise is walking.

6, hot tea is better than cold drink: medical research shows that: heatstroke prevention and cooling, hot tea is better than cold drink, and lasts longer. Tea is rich in potassium. Increased sweating in summer often leads to excessive loss of potassium ions. Potassium and sodium maintain normal osmotic pressure and acid-base balance inside and outside cells, which has an important influence on nerve and muscle function, especially the normal movement of myocardium. When potassium is insufficient in the body, people often feel tired and weak, lose appetite, reduce heat resistance, and even lead to heatstroke. Drinking tea every day in summer can supplement potassium, improve heat resistance and effectively prevent heatstroke.
