As the saying goes, "it's cold in Sanjiu, and hot in volts." The solar term on July 7 is a light summer, and the ancient book Qunfangpu says, "This is not the end of summer." Because after the slight heat, the hottest dog days of the year are coming. The dog days are the hottest time of the year, with concentrated rain and sunset. Notes on the Sacrifice to the Suburbs in Hanshu said: "The sleeper said that Yin Qi would get up, but he was forced by the sunset and did not get up. Therefore, it is hidden because of the name. " On the solstice of summer, the days are long and the sun angle is the highest, but it is not the hottest time of the year, because the heat near the surface is still accumulating and has not reached the maximum. After the summer solstice, the sunshine time decreases day by day, but the temperature continues to rise day by day. From summer to the third Geng day in the future, it began to decline. As the saying goes, "summer heat is closely related to summer heat, and the temperature is rising." This time is called dog days.
People have already experienced the sultry heat in the dark. It is understood that this year's "dog days" are 40 days, that is, the first, middle and last three days, which is the most humid and sultry 40 days in a year. Experts remind that people should not only focus on preventing heatstroke in the "dog days", but also conform to nature and reconcile and correct the balance of yin and yang in the body. This season's health preservation focuses on nourishing lung and kidney, strengthening spleen and eliminating dampness.
Sauna cleverly prevents heatstroke and colds.

"Eliminating evil" in dog days
Fu means lurking, and the "fu" of "dog days" is "fu evil", which is the so-called "six evils" in summer evil.

High temperature and high humidity make people easily "irritable"
People's emotions are closely related to the external environment. Generally speaking, a low temperature environment is beneficial to people's mental stability. In midsummer and hot summer, people sleep shorter at night, have poor appetite, eat less and sweat more, so the metabolism of electrolytes such as calcium, magnesium, phosphorus, potassium, sodium, zinc and iron in the body is disordered, which affects the functional activities of the brain nervous system and has a negative impact on psychology and emotion.
