First of all, Bian Xiang Xiao tells you the parts of the human body that are most afraid of cold. Let's do their warm work and keep you warm for a winter.
1, warm feet. Feet are far from the heart, blood circulation is easily affected, and the subcutaneous fat layer is thin, which has poor thermal insulation and is easy to catch cold. Keep your shoes and socks warm and dry in winter; After sitting for 2~3 hours, you can get up and walk for 10 minutes to promote blood circulation in your feet. In addition, after soaking your feet with hot water before going to bed, massaging your feet with your palm for about 10 minutes can also play a health care role.
2, the head is warm. The head is the coldest place. Why? "The head is the meeting of all the yang", and the human body's meridians are mostly gathered in the head, and the head is unprotected. Just like a thermos without a lid, the yang in the body is the easiest to dissipate. So it is necessary to wear a suitable hat when going out in winter. The temperature is low in winter, so be careful when choosing hats, and keep warm, such as knitted hats, knitted hats, cotton hats or velvet hats, so as to better protect your ears and head.
3. The neck is warm. Neck joint, body follows trunk. It is a very important part of the human body. When the human neck catches cold, it may lead to local vasoconstriction, rapid reduction of blood, and even dizziness and insufficient blood supply to the brain. Therefore, when you go out in winter, you must prepare a warm scarf to resist the cold and prevent colds.
4. Warm knees. Old people must pay attention to keeping their knees warm in winter. In fact, this is also reasonable. Knee joint has less fat and is easily stimulated by cold. Moreover, in winter, the blood supply around the knee joint will be reduced, and the ability to protect and regulate the body will also be reduced. Cold air is easy to invade and easily induce knee pain.
5. Warm your waist. "The waist is the house of the kidney". When the waist is stimulated by cold, the "innate foundation" of people will also be implicated. Middle-aged and elderly people easily stimulate nerves after encountering cold wind, causing back pain and even recurrence. In addition to adding clothes in time, you should also pay attention to covering the quilt at night; Before going to bed at night, you can rub your waist with your hands to warm it up. You can choose a belt to keep warm if necessary.
In addition to choosing clothes that suit you to keep warm, you also need to choose the right ingredients to condition your body and provide enough energy for your body every day.
1, cellulose root food. Such as taro, sweet potato, potato, radish, lotus root, Chinese cabbage and so on. Because these foods are rich in inorganic salts, they can replenish inorganic salts to the human body in time and enhance the human body's ability to resist cold. It is not difficult to understand why Beijing people are "obsessed" with Chinese cabbage and the custom of adding radish, pumpkin, potato, wax gourd, green onion and other foods. One is that there are few varieties of vegetables in winter because of geographical location, and the other is that this kind of food can keep out the cold.
2. Warm meat. For example, mutton and beef are rich in protein and fat, which can invigorate qi and promote blood circulation, promote metabolism and provide enough energy, thus playing a role in keeping out the cold.
3. Foods with high iron content. Such as beef, fungus, red dates, red beans, celery, spinach and so on. Eating more foods rich in iron can enrich blood, accelerate blood circulation and generate enough heat, thus enhancing resistance to cold.
4. Foods rich in iodine. For example, in laver, kelp and shellfish, iodine is an essential element to synthesize thyroxine, which can convert protein and fat into energy. If you take some iodine properly, the energy conversion will increase, and people will naturally not feel cold.
5, spicy food, such as pepper, ginger and so on. This kind of food is spicy and irritating, which can stimulate people's appetite, accelerate blood flow, stimulate the stomach and accelerate the digestion of food, so eating spicy food properly can also resist the cold.
7. Eat more foods rich in vitamins. Such as milk, wax gourd, pumpkin, carrots, fresh vegetables, fruits and so on. They are rich in vitamins, which increase the cold tolerance of human body, regulate the balance of hormones in the body, and make people more afraid of cold.
Off-topic-the difference between beginning of winter and winter solstice
Friends who are familiar with the 24 solar terms know that there are two solar terms in winter, one is beginning of winter, and the other is the winter solstice. Many friends will confuse the winter solstice with the solar terms in beginning of winter. Generally speaking, beginning of winter is in 165438+ 10, and the winter solstice is in 65438+February.
From the time point of view, beginning of winter, as the first solar term in winter, is around165438+1October 8 every year; After beginning of winter, the sunshine time will continue to shorten, and the height of the sun will continue to decrease at noon, so China often takes beginning of winter as beginning of winter. On the solstice in winter, the direct sunlight reaches the southernmost point of the year, almost directly on the tropic of Capricorn.
Seen from the climate, China has a vast territory, and the north and south span dozens of latitudes, so there is a temperature difference between the north and the south. However, after winter, the temperature difference between the north and the south widened. Many places in the north have been dry, everything is withered, and the cold is pressing; South China is still green mountains and green waters, birds and flowers, warm and pleasant.
