What are the precautions for the slight cold solar terms?

1. When dealing with severe cold, people first think of adding clothes, but they often wear thick clothes and ignore the cold protection of their heads, and even regard hats as unimportant things. In fact, the human head is closely related to the thermal balance of the whole body. There is a folk saying that "wearing a cotton-padded hat in winter is like wearing a cotton-padded jacket". In cold conditions, if you just wear warm clothes instead of a hat, the heat of your body will quickly dissipate from your head. The proportion of this heat loss is quite large. Wearing a hat outdoors in winter, even a thin hat, has a very obvious cold-proof effect.

In the cold winter, many people like to wear masks when they go out. Wearing a mask can really prevent respiratory diseases and resist the cold. But when wearing a mask, be sure to cover your mouth and nose and pay attention to cleaning the mask. Neither teenagers nor adults advocate wearing more masks. They should always be tested by cold to improve their disease resistance, which is good for their health.

3. The air pressure is relatively low in winter, and the oxygen content in the air is relatively reduced. In order to keep warm indoors, doors and windows are closed and the ventilation is poor. This further reduces the indoor oxygen, which often makes people feel depressed and chest tightness. Many people like to sleep with their heads covered, especially in winter because of the low temperature. Some people like to bury their heads, faces, mouths and noses in quilts. In the case of limited indoor air conditions, this will cause insufficient oxygen. The harm of sleeping with your head covered is that the quilt is poorly ventilated, the air is dirty, and the human body can't exchange gas normally, which makes the fresh oxygen in the quilt less and less, and the carbon dioxide accumulates more and more, which is easy to cause hypoxia symptoms. In severe cases, people will have nightmares, mental fears and suddenly wake up from lack of oxygen. Over time, it will also cause sequelae such as neurasthenia.

4, folk proverb: "Winter moves, less sick; Lazy in winter, drink a bowl of medicine. " This shows the importance of winter exercise. In this dry and cold day, we should do more outdoor sports, such as jogging, skipping rope and kicking shuttlecock in the morning. Also be calm and optimistic, don't worry about trifles, be calm and add fun. In this solar term, people with heart disease and hypertension often get worse, and the number of people suffering from "stroke" increases. Chinese medicine believes that the blood in the human body is easy to flow when it is warm and easy to stagnate when it is cold. The so-called "blood coagulates when it is cold" is the truth. Therefore, warm-keeping work must be done well, especially for the elderly.
