With the coming of winter and the decreasing temperature, some people are more and more keen on sports in order to ensure their health. Experts point out that cold weather and poor air quality in most places in winter are harmful to health. Therefore, experts put forward four suggestions for winter fitness:

First, the exercise time is best arranged after dinner. Dr. Xu Xiuzhen, chief physician of Lanzhou Huaxia Hospital, said that it is not impossible to do morning exercises in winter, but because it is generally cold in the morning, the trees in the park need metabolism.

Discharge carbon dioxide and absorb oxygen, which leads to the increase of carbon dioxide content in the air, so winter morning is not the best time for exercise.

After dinner, the temperature is relatively high, and the carbon dioxide content in the air is less. After a day's work, it is also beneficial to relieve fatigue. Dr. Xu Xiuzhen said that when exercising in the afternoon, it is best not to eat too much at dinner, but also to exercise moderately, which should not exceed the body's capacity. Walking is a good choice for the elderly.

Second, try to choose an outdoor place with sufficient oxygen for exercise. It is cold in winter, and many people like to go to gymnasiums, swimming pools and other indoor places to exercise. Dr. Xu Xiuzhen said that the air quality is very poor in winter, and it is even worse in places where there are many people indoors. If it's not a professional training, it's best to choose the right time to exercise in a place with plenty of oxygen and fresh air outside.

Third, develop regular work and rest habits. In winter, many people are used to sleeping late in the morning and staying up late when they are in good spirits at night. Because of irregular life and lack of exercise, the body's resistance is reduced. Not only is it unclear at work, but it is also easy to get sick. In this regard, Dr. Xu Xiuzhen said, we must form regular work and rest habits and exercise regularly, which can not only ensure energy, but also enhance resistance.

Fourth, three meals a day should also form a regular diet. Dr. Xu Xiuzhen believes that the sentence "Eat well in the morning, eat well at noon and eat less at night" has certain scientific truth. There must be a day's activities after breakfast, so be sure to ensure nutrition; Because the physical and mental labor consumption during the day is large, you must eat at noon; Because you have to rest at night, your digestion is reduced, and you should eat less dinner.
