Isn't winter suitable for sports? Why?

Winter is more suitable for aerobic exercise, and the temperature is too low for exercise.

First of all, aerobic exercise is the first choice to improve health because of its small amount of exercise. As the saying goes, "Life lies in exercise". Aerobic exercise can make people inhale several times more oxygen than usual, promote tissue metabolism, make the body full of nutrition, and enhance muscle strength, endurance and body immunity.

At the same time, large muscle groups continue to do rhythmic and rhythmic exercise, which not only exercises muscles, but also drives the human circulatory system to strengthen operation, which can obviously improve the nutrition and lipid metabolism of the heart, thereby enhancing cardiopulmonary function and exercising cardiopulmonary endurance, so it is beneficial to health.

Secondly, aerobic exercise for a long time, there is fat, shaping a beautiful figure. Various aerobic exercises need to consume calories and burn body fat. The longer you exercise, the more fat you burn, which can reduce the percentage of body fat. At the same time, during the exercise, the muscles are well exercised and the flexibility of the body is well enhanced, and finally the purpose of losing weight and shaping is achieved.

Finally, relieve mental stress. Aerobic exercise is a positive way of mood regulation. Through the transfer and regulation of excitability of nervous system, it can relieve mental stress, balance mental state and improve sleep.

Matters needing attention in winter exercise

1, watch the weather outdoors. Don't exercise outdoors in the following situations: First, the temperature is lower than MINUS 10℃, which will not only greatly reduce the quality of exercise, but also be easy to get injured; Second, on windy days, exercise in this environment is likely to cause cold and chapped skin; Third, on a foggy day, smog will stimulate respiratory mucosa and induce rhinitis and asthma.

2. The preheating time should be long. Warm-up activities before winter sports must be fully in place, otherwise it is likely that muscle strain and joint sprain will be caused by low temperature, reduced muscle extensibility and stiff joints.

Generally speaking, the warm-up activity before exercise is about 5 minutes, but the warm-up time in winter is twice as long, and it is best to reach 10~ 15 minutes. When warming up, it is best to do dynamic stretching first, and then do brisk walking or jogging with a certain intensity until you sweat slightly and your pores open.

3, clothes should not be too tight or too thick, do not wear a mask. Winter sports clothes should be light and soft, not too tight. You can wear more at first, warm up until your body gets hot and starts to sweat, and then take off the extra clothes.

Need special reminder, don't wear a mask when running in winter, because most masks are not breathable enough. When running, the air circulates in the mask, which not only lacks fresh oxygen, but also inhales too much waste carbon dioxide, making people dizzy and short of breath. If you are afraid of cold air, you can use a triangle towel to keep warm from the wind.

4. It is best not to breathe with your mouth. In cold weather, you should mainly breathe through your nose, not open your mouth. Because the nasal mucosa is rich in blood vessels and the cavity is curved, it has a warming effect on the inhaled cold air, which can avoid respiratory tract infection, sore throat and cough caused by cold air directly stimulating the throat.

If you do a lot of exercise and can't get enough oxygen by inhaling through your nose, you have to use your mouth to help you breathe. In general, the mouth is open, the upper teeth touch the lower lip, and the tongue licks the upper jaw slightly, so that cold air can enter through the teeth and be inhaled through the tongue without seriously stimulating the respiratory tract.
