What season is the summer heat? Is it the hottest time of the year?

Summer is the hottest in a year. Summer solar terms are the period with the most sunshine and the highest temperature in South China, the period with the richest precipitation, the most common thunderstorms and the most concentrated days with high temperature above 30℃ in the west of South China, and the period with the most frequent high temperature above 35℃ in the east of South China.

Every year on July 22 or 23 of Gregorian calendar, when the sun reaches 120 degrees, it is a great summer heat. Before and after the "mid-crouching" is the hottest period of the year. Extreme high temperature weather often occurs in many areas of our country. There are folk proverbs such as "Misgurnus died of heat before and after the great summer heat" and "When the great summer heat comes, the summer heat will come".

Precautions for high temperature in summer:

In summer, ultraviolet and infrared rays are strongest every morning 1 1 to 4 pm. Excessive ultraviolet rays can cause damage to the skin and eyes, causing skin cancer. However, long-term exposure to infrared rays will increase the intracranial temperature, cause meningitis and heat stroke. So try to avoid outdoor sports when the sun is strongest, let alone naked sports.

Excessive sweating and salt loss in summer lead to sodium metabolism disorder and cramp. Therefore, it is very important to replenish water in summer exercise in time.
