Twenty-four solar terms: light summer or big summer?

There is a saying in our country's folk meteorological proverb: "It's a big summer and a small summer, and it's steamed on the top and cooked on the bottom". Slight summer heat and great summer heat are two solar terms connected before and after, both in the hot summer season. So whether it's a little summer heat or a big summer heat, let the old calendar introduce you to one or two.

A little summer heat or a big summer heat is recorded in the twenty-four solar terms in ancient China: "June Festival ... summer heat is also hot, divided into sizes, small at the beginning of the month, large in the month, and still small today." There is also a solar term folk song: "Little summer is not hot, big summer is three days." It means that during the summer, the weather begins to get hot, but it is not the hottest.

According to the ancients, a little summer heat is a little summer heat, and it won't be hot until the middle of June in the lunar calendar. However, this is not the case. In fact, summer heat and summer heat are both masters of making high temperature. There is a saying among the people about the heat degree of summer heat-"Summer heat, summer heat, beware of heatstroke;" Hot weather, hot weather, hot every day. " So it's not "a little hot", but "very hot" and "very hot every day" High temperature comes quickly and lasts a long time.

Precautions for health care in summer: It is advisable to stay up late and get up early in summer. Summer is characterized by long sunshine hours, early dawn and late darkness. Therefore, people's daily life and schedule should be adjusted accordingly, and it is better to go to bed late and get up early. It is best to get up regularly to protect the biological clock from being affected.

Don't wear shirtless clothes in summer. Some people like to enjoy the cool naked in summer, thinking it's cool to go shirtless. In fact, it may not be so. When the temperature approaches or exceeds the body temperature, the shirtless person will feel hotter rather than cooler. Because human body temperature regulation depends not only on skin evaporation, but also on skin radiation.

When the outside temperature exceeds 37℃, the body temperature mainly depends on skin evaporation to dissipate heat; But when the temperature continues to rise, the skin can not only emit heat, but also absorb the heat of the external environment, making people feel more sultry.

Therefore, when going out, you must do a good job of heatstroke prevention and cooling, bring umbrellas, sun hats and other tools, drink plenty of water, and try to avoid going out when the sun is hot in the afternoon.
