People pay special attention to the topic of winter health care. What pits do you need to avoid in winter health care?

First, avoid going out to exercise too early. For the elderly with cardiovascular and cerebrovascular diseases, winter exercise should not be too early. This kind of people have poor adaptability to the sudden drop of temperature, and their blood vessels are easily contracted by cold stimulation. If they do a lot of exercise, their heart rate will increase and myocardial oxygen consumption will increase, which will lead to an increase in blood pressure and induce cardiovascular diseases. So it's best to go out for exercise after the sun comes out, or choose to do it in the afternoon or evening. In winter morning, the cold weather is easy to make the blood vessels of diabetic patients contract, leading to the increase of blood sugar and blood pressure. Therefore, diabetic patients should not go out to exercise too early. People with diabetes also need to prevent fractures. If there is ice on the outdoor ground, it is best not to go out. Diabetic patients should not exercise on an empty stomach. Take some sugary foods with you during exercise and replenish them in time when necessary to prevent hypoglycemia.

Second, the more you cross, the warmer you get, and the cold wind blows, making the already cold winter even more chilly. What should I do if the weather is so cold? Our natural response is to put on more clothes, so that our bodies will be warm. Actually, this is a misunderstanding. Wearing too much will not make your body feel warmer. The main function of wearing clothes is to resist cold air and keep your body warm. If we wear a lot of clothes, it will only affect the blood circulation of our body and make us feel very cold. Moreover, some people like to wear warm clothes to sleep in winter, thinking that only in this way can they keep warm and not catch a cold, let alone keep warm, which is not conducive to health.

Third, do warm-up activities before exercise. Don't forget to do warm-up activities before exercise. Because in cold conditions, human muscles are stiff and joint flexibility is poor, which is prone to muscle strain or joint contusion. Exercise intensity should be properly arranged, especially the running speed should be gradually increased from slow to fast, and the amount of exercise should vary from person to person, step by step, especially for the elderly, the infirm and children, and the exercise intensity must not be too large. It's best not to breathe through your mouth, but to use your nose when exercising. Because the cold air filtered by the nose is clean, moist and not too cold, it can protect the respiratory system well.
