What makes you get up early in the cold winter?

After the twelfth lunar month, all parts of China entered the coldest season. This coincides with the slight cold and severe cold solar terms in China. As the saying goes: "wax gas, Bala, frozen chin", and "slight cold, great cold, cold into ice hockey" argument. Slight cold refers to the degree of cold. Literally, great cold is greater than slight cold, but in meteorological records, it is often slight cold but colder than great cold, which can be said to be the coldest solar term among the 24 solar terms all year round. As the saying goes, "Cold is in Sanjiu", and "Sanjiu" is just a slight cold solar term. Because of this, in the cold winter, we should pay more attention to cold protection and health care in food, clothing, housing and transportation, spend the coldest season of the year safely and welcome the arrival of the New Year happily.

In terms of clothes, in the cold December, most people often wear too much, especially children. When the weather is a little cold, adults will wrap them tightly for fear of freezing them. But I don't know that wearing too thick clothes has at least three disadvantages: First, wearing too thick clothes in not very cold weather is easy to make the air layer inside the clothes form a microclimate with high temperature and high humidity, and the resistance of the human body to heat dissipation and moisture dissipation increases, which affects the adjustment of heat balance; When the thickness of air layer inside clothes exceeds 15 mm, air convection increases, heat loss increases and warmth retention decreases. Second, wearing thick clothes too early will inhibit the body temperature regulation function, weaken the cold resistance, and easily catch a cold. Third, in the cold winter, wearing too many clothes makes you bloated, inconvenient to move, and consumes more physical strength; Children are overwhelmed by clothes, which hinders their physical activities and affects their physical development. But some people who love beauty "only seek elegance, not temperature", which is also undesirable. Therefore, in cold winter, we should pay attention to keep warm. "Cold starts from the feet", so it is particularly important to keep people's feet warm. When the elderly go out, it is best to put on cotton shoes, towels and socks, and wear hats and scarves to prevent their feet and heads from catching cold.
