Last week, Beijing issued the first cold wave blue warning signal in history, and the cold winds followed. Experts pointed out that in the face of cold weather, it is not desperate to wear thick clothes to warm up. Antifreeze and warmth protection are tips.
Keep warm "Start from scratch"
Keep warm in the winter, we must first attach importance to the head. Miao Jiwen, deputy chairman of the Chinese Association of Health Workers, pointed out that the head is called the “Zhuyang meeting†in Chinese medicine. Under low temperature conditions, the head is in a state of rest for a long time without a cap, and the body’s heat will be A lot of loss from the head.
Many people are prone to headaches in the winter, which is caused by shrinking blood vessels due to cold weather. Therefore, when going out or when the room is not warm, be sure to wear a hat to keep the head warm. In particular, patients with cerebrovascular disease, the head cold is more likely to make the disease attack. Many women do not like to cover their hair with thick hats. Choosing not to wear hats or wearing hats that are warmer than decorative ones is not correct.
Wash your hair in winter should choose when the temperature is high during the day. After washing your face, it is best to go out after half an hour to reduce the damage of the cold wind to the facial skin. In addition to the hat, it is best to wear a large scarf and mask to protect the face and prevent frostbite.
Heavy clothing is not heavy
The thicker the dress, the more layers the warmer? Miao Jiwen pointed out that it would be better to put a three-layered three-layered package into a "dreadlock" and put on an airtight leather garment.
Experts point out that instead of wearing thicker and warmer clothes, it depends on the warmth of the clothes chosen. Because the clothes do not produce heat, they mainly isolate the cold air, buffering the cold air outside and the hot air on the body surface. The convection causes the body's heat to be preserved. If the number of layers of clothing is increased, air convection in the clothes will be significantly increased, and the warmth will be reduced, which will also inhibit the ability to keep out the cold. Therefore, clothes should use fluffy and warm down clothing and air should not penetrate the leather clothing; wear clothes must be selected warm, fit body type, the coat should choose good wind performance.
The more active the more cold
Many people are more cold and do not love activities. They are afraid of the loss of calories from the body. In fact, exercising more will help improve the ability to keep out the cold.
Miao Jiwen suggested that under the premise of preparing for antifreeze, it is necessary to carry out cold-resistant exercises, such as running and walking, but the time should not be too long, and it can be about 20 minutes. When you come back from the outside, you must use your hands to rub each other, rub your face and feet with your hands, and promote blood circulation. Do not immerse the affected area with fire, sleet, cold water and beating after frostbite.
In order to prevent the face from being frozen before going out in the morning, it is necessary to perform preventive exercises such as massage the face with cold water and massaging it to a fever to enhance the resilience of the face to the cold wind.
Wearing "small shoes" is easy to get frostbite
As the saying goes, "Chill from the feet." The foot is farthest from the heart, and the blood supply is slow and less, and the subcutaneous fat is thinner, so it is easy to catch cold. Therefore, experts emphasized that we must pay attention to keeping our feet warm.
Many people wear thick shoes and socks in winter. Why do they feel cold? Miao Jiwen pointed out that this may be because the shoes and socks are worn too tightly. Winter footwear must not be too tight, because it will lead to poor blood flow to the feet, the heat can not reach the foot, over time, the feet will be colder, it will also cause frostbite, in addition, but also ground roasted, Socks and insoles were changed, and hot water was used to treat the feet. Usually, hot feet in pepper and ginger water were used to prevent foot pain.
