It's cold, so it is necessary to wear more clothes to keep warm. Now the temperature has started to drop all over the country, and it even started to snow in some places. In winter, you must choose the right tips to keep warm, not the more you wear, the better, to avoid going into some misunderstandings. Some men drink a lot of alcohol in order to raise their body temperature, which can really make people feel hot and dry for a while, because alcohol can promote the body to emit heat, but after alcohol is strong, the body will emit a lot of heat, which will also lead to the body getting cold.
In fact, wearing too many clothes in winter will not produce heat, but only play a certain role in isolation, which can only alleviate the temperature difference between the outside air and the body surface and save heat. Wearing too much clothes will inhibit the adaptability of thermoregulation, thus weakening people's ability to resist the cold. Wear a moderate thickness in winter, not too much.
Close the doors and windows in winter. Some people close the doors and windows in order to keep the temperature stable. In fact, this is a wrong method, because we will produce a lot of chemicals in the process of metabolism, and the air is rich in dust, carbon dioxide and microorganisms, which can easily lead to cough and cold. So always open the window to keep the indoor air fresh.
People who wear masks to keep out the cold will wear masks directly when they go out in cold winter. In fact, the heating effect of the mask is not very good, and at the same time, it will reduce the immunity, because our nasal mucosa contains a lot of spongy vascular network and blood vessels, and the blood circulation speed is very fast, which can quickly heat the inhaled air, while our nasal catheter is tortuous, which can increase the area of the wall mucosa, thus enhancing the heating. The cold air we inhale mainly enters the lungs directly through the nasal tube, because it has a certain warming effect. When wearing a mask, the air exhaled in the body will directly turn into water on the mask, which will not only cause the face to feel cold, but also be harmful to oral health.
Washing your face with hot water will be warmer. Some women are used to washing their faces with hot water in the morning. Under the stimulation of cold, our face will be stimulated by cold, which will shrink capillaries and sweat glands, expand rapidly when it meets hot water, and then return to low temperature. Tips to keep warm in winter In order to avoid entering the above five misunderstandings, you can usually eat more animal livers or carrots, because they contain a lot of vitamin A and vitamin C, which can enhance the cold tolerance of the human body.
