2. Sexual life should be controlled. Sexual intercourse in winter is of great significance to health preservation.
3. Wear a scarf in winter and don't cover your mouth. Scarves are mostly made of wool, rabbit hair and blended wool, and the fibers are easy to fall off. Because it is easy to absorb dust and germs, and it is not often washed, when the scarf comes into contact with people's nose and mouth, the fallen fibers, dust and germs can easily enter the body with breathing, making people prone to respiratory diseases.
Wearing a cotton-padded hat in winter is like wearing a cotton-padded jacket. Wearing thick clothes, heat is mainly lost from exposed parts such as the head and hands, so it is very important for women to keep fit and keep their heads warm in winter.
5, pay attention to keep your feet warm. In winter, the size of shoes and socks should be slightly larger, and there should be a gap between feet and shoes, which is to use the heat insulation effect of air to enhance warmth. The thickness of the sole should be appropriate, because the thick sole makes the shoes have good cold resistance.
6. Create an ideal clothing environment. The surface temperature of clothes is about zero degrees Celsius, and the temperature between the inner layer of clothes and the skin is always kept at 32℃ ~ 33℃, which can create a good microclimate zone around the human body, buffer the invasion of cold climate outside and keep the human body at a constant temperature.
7, often open the window, often ventilated. You should open the window regularly for ventilation to keep a certain amount of fresh air indoors.
8, 65438 08℃, the ideal temperature. In winter, the temperature difference between indoor and outdoor is large, so it is generally appropriate to keep 16℃ ~ 20℃ indoors, and 18℃ is the most ideal.
9, relative humidity 45% ~ 60%, healthy humidity. 45% RH ~ 60% RH is called healthy humidity. If the indoor humidity is too high, it is more difficult for the human body to dissipate heat. Indoor humidity is too low, the air is dry, and people's respiratory tract is dry and uncomfortable, which will cause dry mouth and sore throat.
10, don't sleep with your head covered. When you sleep with your head covered, the air in the bed will not circulate, and there will be less and less oxygen. People will feel chest tightness, nausea or wake up from sleep and sweat.
