In cold weather, in addition to keeping the core parts of the body warm, many people also like to put a "coat" on their nose and mouth. However, when cold air enters the lungs from the outside through our nasal cavity, there is no need to wear a mask to resist the "cold" in the air because the rich nasal mucosa and respiratory tract pass through blood vessels and spongy vascular network, and the temperature is close to body temperature. As we all know, the cold resistance of human body should be enhanced through daily exercise. If you rely on a mask for cold protection for a long time, your body will be more likely to catch a cold. People with poor resistance should try to wear scarves, gloves or warm shoes and boots to keep warm in cold weather. Of course, for friends with respiratory diseases or when the air quality is too poor, it is still recommended to wear a mask to go out.
2/ Drink to keep out the cold
Isn't a person afraid of hurting his stomach when he is drunk? I believe that sometimes in cold weather, even if I am not good at drinking, I will sit on the wine table at the invitation of my relatives and friends. However, drinking alcohol does make people feel hot all over, but this is the result of alcohol prompting the human body to emit primitive heat. After drinking alcohol, a lot of heat in the body will be released from the body, which will make people feel like they have just taken a bath and lead to a cold after drinking. And if you have just finished drinking, don't go out right away, because it is easier to catch a cold because of cold outside and heat inside.
3/ Keep warm at close range
If your hands and feet are cold from the outside, I believe that many times you will get used to walking back to the house immediately and putting your hands and feet on the heater or by the fire to keep warm. In fact, you don't know, this will cause more serious frostbite!
This is because the blood vessels contract and the blood flow decreases after the hands and feet catch cold for a long time. At this time, hands and feet are in close contact with the heat source for heating, which will paralyze blood vessels, lose contractility, appear arterial congestion, telangiectasia, enhance permeability, and cause local congestion, which is easy to form chilblain. The correct way is to gently rub the cold hands and feet to make them slowly return to normal temperature.
4/ Keep warm and only warm your feet
Everyone has a love of beauty. At present, the needs of urban life, I believe that whether the weather is cold or sunny, "it is better to be elegant, wear less clothes and thick shoes!" "Hidden rules will be recognized more or less. So if your feet are warm, is your body really warm?
This view is wrong! When our body is cold, the first organ is actually our heart, and then the body will feel locally cold. Moreover, stomach cold and abdominal pain are also acute diseases that are more likely to occur in some women in winter, especially during menstruation. Keeping warm is particularly important. Only when the feet are warm can the body really warm up.
5/ Eat meat to keep out the cold
Meat is undoubtedly a tonic, which is not only nutritious, but also delicious. Dog meat, mutton, beef and venison have relatively good cold-proof effects, and the contents of protein, carbohydrate and fat in these kinds of meat are high, which is beneficial to tonifying kidney and strengthening yang, invigorating qi and promoting blood circulation at moderate temperature. Regular consumption can accelerate metabolism and enhance endocrine function, thus achieving the effect of keeping out the cold.
However, people often ignore the shortcoming that meat is not easy to digest and absorb. If you eat more for a long time, eating a lot of meat will often overwhelm the digestive system for middle-aged and elderly people with poor gastrointestinal function or decline, and some "by-products" in meat, such as excessive lipids and sugars, are often the causes of common diseases and frequently-occurring diseases such as cardiovascular and cerebrovascular diseases and cancer. It is not necessary to have a light diet in autumn and winter, especially vegetables. Modern nutrition believes that fresh fruits and vegetables contain a variety of vitamins and trace elements, which are essential nutrients for human body.
After reading the above misunderstandings, have you been shot? It is very important to maintain health in autumn and winter, so you should eat well and sleep well. As the saying goes, "autumn hides the king, winter hides the king." I hope everyone can avoid these misunderstandings of keeping warm and keeping fit.
