In winter, what weather is suitable for sports? What should I pay attention to?

The sun moves after it comes out. In winter, the temperature difference between indoor and outdoor is large, the climate is dry, and people's physiological functions are in a relatively slow state. When doing physical exercise in winter, we should take corresponding protective measures. 1, winter outdoor sports, it is best to choose between 8: 00 am and 9: 00 am or 4: 00 pm after sunrise. This is because before the sun comes out, it is easy to produce dense fog in winter, and there is a lot of pollution in the air, which is not good for human body. It is not easy for people to come out to exercise too early. 2, people just transition from indoor to outdoor environment, must be prepared to warm up, especially the elderly and children, to prevent unnecessary injuries. Take a spare suit for outdoor sports in winter. People of different ages should choose different ways of exercise. Strenuous exercise such as long-distance running is more suitable for young people, and the elderly can walk every day to meet functional needs. Keep warm immediately after sweating, which is also the key to prevent upper respiratory diseases and colds. If you are a person who participates in outdoor sports for a long time, you can wear more and less according to your own habits; If you are not a regular exerciser, you should wear long clothes and trousers. But the most important thing after exercise is to keep warm and add clothes in time after sweating. Outdoor dress-the weather conditions faced by outdoor activities in winter with three-layer method are generally more complicated. Therefore, whether you are walking or climbing a mountain, you should adjust your clothes at any time with the change of temperature. Simply put, outdoor dressing in winter is usually divided into three layers: perspiration layer, warmth layer and functional layer (wind and water). 1, never use cotton products for personal clothes, because although it absorbs sweat, it is not easy to dry, so you must choose materials with strong perspiration function. 2. Various wool fabrics can be selected for the thermal insulation layer. After polyester processing, it is warm, light and small. In the changeable outdoor environment, a windproof and waterproof garment is very important. Especially don't forget to protect your head and feet. Studies show that 60% of the body's heat is lost from the head.
