1, the misunderstanding of health preservation in winter
Myth 1: The more clothes you wear, the better.
Clothing itself does not generate heat, but only acts as a barrier. It buffers the convection between the cold air outside and the hot air on the body surface, so that the heat of the human body can be retained. Physiologically speaking, wearing too much clothes will inhibit the adaptability of the body's thermoregulation function and weaken the body's ability to keep out the cold. Therefore, dressing in winter only needs to reach the appropriate thickness.
Myth 2: Close the doors and windows and catch fewer colds.
Some people lock doors and windows all day in winter, thinking that the indoor temperature is high and it is not easy to catch a cold. That's not true. According to experts, more than 500 kinds of chemicals will occur in the process of innovation, and only 149 kinds will be discharged from the respiratory tract. There are many bacteria, viruses, carbon dioxide and dust in the air. In this kind of air, people have a cold and cough at all, so we should always open the window to keep the air fresh.
Myth 3: Wear a mask to prevent colds.
In fact, the cold air inhaled by the nose is now close to body temperature when it enters the lungs. This physiological function of human body is innate and can be enhanced through training, which can obviously improve people's cold tolerance. Wearing a mask artificially prevents this physiological function from being exercised and makes people's resistance worse. A slight cold is simply a cold.
Myth 4: Drinking white wine can keep out the cold.
Many people think that drinking white wine can keep out the cold. In fact, after drinking alcohol, people are stimulated by alcohol and their blood vessels dilate, which will release a lot of body heat, so they will have a fever, but this feeling will soon disappear. Especially when the heat is released to a certain extent, people will feel cold instead. The reason why cotton-padded jackets and down jackets can keep out the cold is that they can reduce the loss of heat, and the main components of wine are water and alcohol, which not only do not produce heat themselves, but will cause heat evaporation.
Myth 5: Warm your hands and feet before entering the house from the outside.
When many people enter the room from the cold outdoor, they first put their frozen limbs on the heater to bake or soak them in hot water. Originally, this alternation of cold and hot was extremely unlucky for the limbs, which was simply frostbite of the limbs. The accurate method is that the limbs collide with each other, so that the skin temperature naturally rises, then it is soaked in hot water and baked with a heater.
