2. Dressing in spring should pay attention to the principle of "thick below" and grasp the principle of "8. 15". We need to cover it around 8℃. When the temperature is kept above 15℃ and relatively stable, the human body can adapt. In terms of covering time, 1-2 weeks is more suitable, and it takes about 7 days after the temperature rises, and the weak or the elderly have to cover their bodies for more than 14 days to adapt.
3. In spring, we should pay attention to "the lower part is thick and the upper part is thin", and the focus of covering is on the back, abdomen and soles. Keeping your back warm can prevent diseases and reduce the chance of catching a cold; The purpose of keeping the abdomen warm is to protect the stomach, spleen and intestines and prevent indigestion and diarrhea. "Cold starts from the foot", and the nerve endings at the foot are rich and sensitive. Keeping warm can adapt the body to climate change. Pay attention to both ends, and take care of your head, neck and feet in spring.
For the elderly and children, the warmth of the lower body is more precious. Pay attention to wear windproof and warm clothes, shoes and socks when traveling. In addition to keeping warm on clothes, active physical exercise is also a good way to warm up the body, which can enhance the adaptability and disease resistance of the body to external temperature changes. It is particularly noteworthy that you should never stay under the covers and in the heating all day because of the cold, which is also very unfavorable to the blood circulation of the body.
