Winter exercise is more comfortable because of the low external environment temperature and less sweating (the body does not need to find ways to dissipate heat), so the exercise intensity can be slightly increased, and aerobic exercise with small exercise range and high calorie consumption is the most suitable.
Young people can choose high-intensity aerobic exercise such as running, which can consume more calories. Exercise time is longer than that in spring and summer 10- 15 minutes. Explosive anaerobic exercise is not suitable and may cause physical discomfort in cold climate.
Middle-aged people can choose low-intensity aerobic exercise such as brisk walking, jogging and climbing stairs. The physical condition of middle-aged people is generally in a downward trend, so don't give up fitness because of busy work.
For the elderly, cardiovascular diseases are high in winter, so exercise must be mastered. It is best to go out when the sun comes out or the weather is warmer. If you sweat a lot, you should unbutton your clothes and cool down slowly. After exercise, the oxygen consumption of human body will increase, and the demand for blood supply to the heart will also increase. The blood supply of the elderly will be reduced due to vascular stenosis or arteriosclerosis, which will also increase the risk of illness. Therefore, the elderly should appropriately reduce the amount of exercise in winter.
② Exercise in winter to keep warm and cold.
The outdoor temperature is low in the morning, so you should put on more clothes, get ready for activities, and then take off heavy clothes and pants for exercise after warming up. Put on clothes and pants in time after exercise and keep warm. Especially after winter swimming, you should immediately dry your whole body with a soft and dry bath towel, wipe your red skin, keep warm and avoid the invasion of cold evil.
Some people think that exercise itself generates heat, so there is no need to keep out the cold. This is obviously wrong. Exercise speeds up the circulation, and the body is in a state of heat dissipation, so I really don't feel cold. But at this time, the pores are open, and cold air can easily stimulate the body, causing invisible harm. By the time I feel cold, my body has been damaged to a great extent.
Low temperature environment is easy to cause "wind evil" injury, leading to colds, joint pain and even stomach pain. Exposed parts of the body, such as hands and face, are prone to frostbite. Half an hour after the sun comes out, the damage of morning cold can be alleviated.
