First, common sense of keeping warm in winter: the head, chest, abdomen and feet are the key points.

1, keep your head warm

Medical research has found that when the ambient temperature is 15℃, the heat lost from the head accounts for 30% of the whole body heat, and the heat lost at 4℃ accounts for 60% of the whole body heat. In addition, the cold weather makes blood vessels contract, and people will have headaches and dizziness. For people with cerebrovascular diseases, it is easy to induce cerebrovascular diseases.

People often say that wearing a scarf in winter is like wearing an extra dress. After catching cold in the chest and abdomen, it is easy to break the body's yang and lead to a heart attack.

Step 3 keep your feet warm

Feet are farthest from the heart, blood supply is slow and less, subcutaneous fat layer is thin, and warmth retention is poor. Once caught cold, it will reflexively cause the capillary contraction of respiratory mucosa, which will reduce the disease resistance and lead to upper respiratory tract infection. Therefore, we should strengthen the warmth of our feet in severe cold. Old people should wear thick socks and cotton shoes as soon as possible in winter to warm their feet and strengthen their kidneys. People with a history of frostbite should wear it early. In addition, before going to bed at night, scalding your feet with hot water and rubbing the Yongquan point in the center of your feet to maintain good peripheral blood circulation is conducive to health care. For people with a history of frostbite, you can wash and iron your feet with hot water with scallion and pepper.

Step 4 keep your back warm

Traditional Chinese medicine believes that the back is inhabited by kidney veins, and colds often start from the back. Therefore, keeping the back warm can not only prevent colds, tonify the kidney and strengthen the waist, but also prevent the recurrence and aggravation of old diseases. Therefore, it is best for the elderly to add a vest in winter. It is advisable to use cotton or silk floss, which has good heat preservation and cold preservation performance. Wear clothes when you get up at night to prevent catching a cold.

Second, you should also protect yourself from the sun in winter

The sun in winter is comfortable and warm. It is good to sunbathe for a while every day, because proper sunbathing is beneficial to the body's absorption of calcium, but sunbathing should also be limited. If the time is too long, it will be harmful to your health. Because too much Sun Long exposure will damage the skin, destroy the natural barrier of human body, make harmful chemicals and microorganisms in the atmosphere invade human body, cause infection and induce many diseases.

For winter sports, you can choose jogging, cycling and playing Tai Ji Chuan. And you can also choose indoor fitness places, such as aerobics, table tennis, bowling and so on. But when the elderly exercise, they must do what they can, and don't choose those sports with too much activity and too much exercise.

Third, keep warm in winter and eat more foods containing iron and calcium.

Fear of cold is related to calcium deficiency and iron deficiency. People's fear of cold is related to their lack of intake of certain minerals. For example, the content of calcium in human body can directly affect the elasticity and excitability of myocardium, blood vessels and muscles; Iron deficiency in blood is an important cause of iron deficiency anemia, which is often characterized by low fever and hypothermia. Therefore, supplementing foods rich in calcium and iron can improve the body's ability to keep out the cold. Calcium-containing foods mainly include milk, bean products, kelp, seaweed, shells, oysters, sardines, shrimp and so on. Iron-containing foods are mainly animal blood, egg yolk, pig liver, soybeans, sesame seeds, black fungus and red dates.
