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 crouching time is not fixed every year, and the length of crouching time is also different. In a word, from summer to the third "night" in the future, the first onset is 10 day, the second onset is 10 day and 20 days, and the last onset is 10 day.

The date of dog days is the third Geng Day, the first volt, the fourth Geng Day to the fifth Geng Day, and the first Geng Day to the second Geng Day from the summer solstice to beginning of autumn. (Every Geng day 10 day) The number of days in long summer is not fixed. There are four Geng days between the summer solstice and beginning of autumn, with 10 days in midsummer and 20 days when there are five Geng days in midsummer.

In classical Chinese, lying down means lurking. The "crouching" in the "dog days" is the "crouching evil" in the so-called "six evils" (wind, cold, heat, dampness, dryness and fire). In summer, no one knows whether summer evil will gradually sink into the body. In summer, the evil of fire is stronger than gold, and lung qi is injured, which leads to the decline of human immunity and causes diseases such as cold, cough and fever. After entering winter, these diseases will recur. ".Autumn is the season of malaria epidemic, and few crops are harvested on the solstice in winter, and the disease is also very serious. "

Therefore, Huangdi Neijing clearly pointed out that "if you want to be angry, if you love others". Don't hide in an air-conditioned room for fear of sweating. Cold drinks can not only relieve summer heat, but also hurt the spleen and stomach. You know, tea is the best drink to relieve summer heat. Although a cup of hot tea will sweat, it will be followed by a chill. You can't just look at the present, but look further.

Why is it hot after staying?

The higher the surface humidity, the more heat is absorbed and the less heat is released, so the surface heat accumulates, so it gets hotter every day. During the dog days, the accumulated heat on the ground reaches its peak, and the weather is the hottest. In addition, there is much rain in summer, the air humidity is high, and the heat capacity of water is much greater than that of dry air, which is also an important reason for the sultry weather. In August, the subtropical high intensified. Under the control of the subtropical high, the descending airflow inside the high makes the weather clear and partly cloudy, which is beneficial to sunlight, the ground radiation heats up and the weather is hot.

Is it not hot after falling out?

Generally speaking, falling out of the house means falling out of the house, and the heat gradually disappears; Moreover, the summer solar term means that the heat is over and the weather should be getting cooler and cooler. However, in some areas in the south, people who have just felt a little coolness in autumn often feel hot weather at the end of the summer heat. This is the legendary autumn tiger.

The reason for the formation of the autumn tiger is that the western Pacific subtropical high, which controls China in autumn, gradually moved southward, but then moved northward. Under the control of this high pressure, it is sunny and cloudy, with strong solar radiation and rising temperature. Due to the vast territory of China, the performance of Autumn Tiger is slightly different. For example, the autumn tiger in South China comes later than the autumn tiger in the Yangtze River valley, which is generally delayed by 2-4 seasons.

In addition, the annual autumn tiger control time is long and short, ranging from half a month to two months; Sometimes the autumn tiger comes and goes, and then goes back. Author Gu Tieqing: "After summe,
