How should the elderly keep warm in winter?

The winter climate is cold, and the metabolism of the human body is also at a relatively slow level. With the increase of age, the functions of various organs of the elderly are declining, and their thermoregulation and cold tolerance are also gradually declining, which is easy to induce cardiovascular and pulmonary diseases. Therefore, the first condition for the elderly to spend the winter safely is to keep warm. Specifically, we should pay attention to the following aspects:

1. Keep your nose warm. In winter, the blood flow in the nasal mucosa of the elderly slows down, which leads to the weakening of the adhesion of the nasal mucosa to various germs and the weakening of the heating effect on cold air. If you are not careful, you can easily catch a cold or catch other diseases. Therefore, it is best for the elderly to wear masks and hats (wool hats or wool hats) when they go out in winter, and massage their noses several times a day at home to increase the blood circulation of their noses.

2. Keep your abdomen warm. In winter, old people should change their clothes in time with the change of outside temperature. Pay attention to keep warm, especially in the abdomen, to avoid indigestion. Clothes should be made of light, soft, bulky and warm materials, such as wool, silk cotton, down and new cotton. It is not advisable to wear chemical fiber clothing, especially chemical fiber underwear, because chemical fiber underwear is easy to irritate the skin and cause itching.

3. Keep your back warm. If the old man's back is not well kept warm, pathogenic wind and cold will easily invade the human body through the back meridians, damage the yang, destroy the balance of yin and yang, reduce the human immune function, weaken the disease resistance, and easily induce the recurrence of diseases or old diseases. Therefore, in winter, the elderly can wear a close-fitting cotton vest or wool vest under their cotton-padded clothes to keep their backs warm.

4. Keep your feet warm. As the saying goes, "Cold starts from the feet". Feet are far from the heart, blood supply is insufficient, and thermal insulation performance is poor. Once the feet catch cold, it will cause blood vessels to contract, blood flow to decrease, the body's disease resistance to decline, and it is easy to get sick through nerve reflex. Therefore, the shoes and socks of the elderly should be kept warm and dry in winter, and often washed and dried. Take a walk regularly to promote blood circulation in the feet. It is best to wash your feet with warm water before going to bed, and then massage the soles of your feet for 10 minutes.

5. Keep the room warm. In winter, the living room of the elderly must have heating equipment to keep the indoor temperature at 18 ~ 24 degrees Celsius and the humidity at 40 ~ 50 degrees Celsius to avoid the invasion of cold evil. At the same time, pay attention to regular ventilation, usually for 30 minutes at a time. If you feel cold at night, you can use an electric blanket or a hot water bottle.
