What does the solar term slight cold mean?

A slight cold represents the beginning of the coldest day of the year. A slight chill means that the weather is cold but not extreme. In the slight cold season, the direct point of the sun is still in the southern hemisphere, and the heat in the northern hemisphere is still in a state of loss. The heat absorbed during the day is still less than the heat released at night, so the temperature in the northern hemisphere continues to decrease.

Slight cold climate characteristics Slight cold, like great cold, slight summer heat, great summer heat and intense summer heat, are all solar terms indicating temperature changes. Cold means cold, and slight cold means the degree of cold.

The slight cold solar term began to form the most powerful and stable East Asian trough, and the Mongolian cold high and Aleutian low also reached the most powerful and stable period. The scale of the westerly ridge reaches the maximum, which matches the maximum intensity of the westerly wind.

The temperature between the inner layer of clothes and the skin is always kept at 32℃-33℃. This ideal clothing climate can create a good microclimate zone around the human skin, buffer the invasion of the external cold climate and keep the human body at a constant temperature. Clothing should be dark, light and warm. Choose wool, silk cotton, down and other light, fluffy and warm products.

Travel.

There is frequent snowfall in the slight cold solar terms, and the snowy road is slippery. Coupled with the melting of snow during the day and the freezing of roads due to the cooling at night, the number of people falling out will suddenly increase. Doctors suggest that people should wear loose, warm and non-slip cotton shoes and sports shoes when going out in snowy days. The sole should be rough and the texture should be wide and deep. It is best not to wear leather shoes, especially women's high heels. Don't drive too fast when riding a bike. You'd better check whether the brakes are frozen before going out. Pregnant women are inconvenient to move, osteoporosis in the elderly, and falls will have serious consequences. It is best not to go out.

sports

Many people have the habit of getting up early to exercise. When the weather is too cold, it is best to arrange exercise in the afternoon, because the peak of cardiovascular disease is generally in the period of the day when sympathetic nerve activity is strongest, and it is concentrated from 6 am to 12. Especially in winter and snowy days, the cold weather will stimulate sympathetic nerve excitement, induce vasospasm and contraction, and easily lead to acute myocardial infarction, arrhythmia, sudden cardiac death and other cardiac emergencies.
