Exercise. In winter, many people are reluctant to take part in sports because of the cold climate. But as the saying goes: "if you move in winter, you will get less sick;" Lazy in winter, drink a bowl of medicine. " "Practice dog days in summer and practice Sanjiu in winter. "All these show that it is very beneficial to health to insist on physical exercise in winter. Cold-resistant exercise is beneficial to people, and it is helpful to the cardiovascular, respiratory, digestive, exercise and endocrine systems of the human body, thus reducing the occurrence of coronary heart disease, cerebrovascular accident, cold, cough, arthritis and obesity. At the same time, cold tolerance can make people live longer. For young people, cold tolerance can also exercise people's strong will and tenacious spirit, which should be advocated in particular. Although people's cold tolerance is limited, and people with different constitutions have different responses to cold stimuli, it is certain that exercise can improve the body's tolerance to cold. How to take the first step of cold-resistant exercise? It's too late to think about this problem when the cold comes. Because the temperature changes gradually from high to low, people's exercise must also adopt the method of gradually adapting their bodies to the cold. If a person can persist in walking in the wild from hot weather to cold weather every morning and take a deep breath of fresh outdoor air, his cold tolerance will gradually improve. If you add other forms of physical exercise, such as running, playing ball games, climbing mountains and so on. As the temperature decreases, people will not feel cold in cold places.
In winter, in order to resist the cold, people take various measures to keep warm, but the methods must be proper to achieve the purpose of health preservation. Therefore, winter health needs the following points: 1) In winter, you should "go to bed early and get up late" and get up after the sun comes out. Because going to bed early can maintain human yang and keep the body warm, while getting up late can nourish human yin. Do it at sunrise, get up and stop the cold, and ask for its warmth. Don't sleep with your head covered when it is warm. If the air in the bed is not circulating, there will be less and less oxygen. Over time, the air will become turbid. When people sleep in such an environment, they will feel chest tightness, nausea, or wake up from sleep with a cold sweat and feel tired the next day. 2) Keep warm in winter and keep your head warm-the head is cold, the blood vessels contract, and the muscles in the head are tense, which is easy to cause headaches, colds and even gastrointestinal discomfort. Warm back-cold stimulation can affect local muscles or spread to internal organs through acupoints on the back, which is harmful to health. Cold in the back not only causes backache, but also affects the muscles, joints and internal organs of the upper and lower limbs through the cervical vertebrae and lumbar vertebrae, causing various discomforts. Warm feet-once the feet are cold, they can reflexively cause capillary contraction of upper respiratory mucosa, slow cilia swing and reduce resistance. The consequence is that viruses and bacteria take advantage of it and multiply in large numbers, which makes people catch a cold.
