1, winter health tips
1, wear a scarf in winter, don't cover your mouth.
In winter, old people, children, young men and beautiful girls over 60 will wear a scarf when they go out, which can not only keep out the wind and keep out the cold, but also add beautiful elegance. However, when wearing a scarf, don't cover your neck with your mouth. It seems to keep warm, but in fact it is very harmful to the body. Scarves are mostly made of wool, rabbit hair and blended wool, and the fibers are easy to fall off. Because they are easy to absorb dust and germs, and they are not washed frequently, when they come into contact with people's nose and mouth, the fallen fibers, dust and germs can easily enter the body with breathing, making people susceptible to respiratory diseases.
Wearing a cotton-padded hat in winter is just like wearing a cotton-padded jacket.
People put on thick clothes in cold winter, and the heat is mainly lost from the exposed parts such as the head and hands. According to tests, people who don't wear hats at rest will lose a lot of heat from their heads. According to the test, when the ambient temperature is 15℃, the heat lost by the head accounts for 30% of the total heat dissipation of human body, 60% at 4℃ and 75% at-15℃. It can be seen that the warmth of the head is closely related to the thermal balance of the human body. As the saying goes: "Wearing a cotton-padded hat in winter is like wearing a cotton-padded jacket." Therefore, it is necessary to pay special attention to hats in winter to protect ears, and children should pay more attention to wearing hats at any time.
3, 45% ~ 60% relative humidity, healthy humidity
Indoor humidity should be suitable in winter. "Healthy humidity" refers to 45% RH ~ 60% RH.
If the indoor humidity is too high, it is more difficult for the human body to dissipate heat. When the indoor temperature is too high, there will be a sense of oppression; At the same time, when the indoor temperature is low, the humidity is higher than' 80%RH, which will make the human body dissipate heat too quickly and increase the cold feeling.
Indoor humidity is too low, the air is dry, and people's respiratory tract is dry and uncomfortable, which will lead to dry mouth and sore throat. Usually, there is little precipitation, strong wind, dry climate and low indoor humidity in winter in northern China. Especially in winter, the stove fires to keep warm and the indoor air is dry. It is often necessary to put a kettle on the stove, let the water in the kettle transpiration, discharge the indoor steam, or spray water on the ground to increase the air humidity. You can choose a humidifier to better control the air humidity.
