How to keep fit in winter?

first, it is best to arrange the exercise time after dinner. Dr. Xu Xiuzhen, chief physician of internal medicine of Lanzhou Huaxia Hospital, said that it is not impossible to do morning exercises in winter, but it is not the best time to do exercises in winter because it is generally cold in the morning and the trees in the park have to metabolize, expel carbon dioxide and absorb oxygen, which leads to an increase in carbon dioxide content in the air. After supper, 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's best not to eat too much at dinner, but also to exercise moderately, which can't exceed your body's endurance. For the elderly, walking is a good choice.

2. Try to choose outdoor places with sufficient oxygen for exercise. It is cold in winter, and many people like to exercise in indoor places such as gymnasiums and swimming pools. Dr. Xu Xiuzhen said that the air quality is poor in winter, and it is even worse in places where there are many people indoors. If it is not professional training, it is best to choose the right time to exercise in places with sufficient oxygen and fresh air outside.

third, develop a regular habit of work and rest. 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 irregularity and lack of exercise, the body's resistance is reduced, and it is not only unclear at work, but also easy to get sick. In this regard, Dr. Xu Xiuzhen said, we must form a regular habit of work and rest, and exercise regularly, which can not only ensure energy, but also enhance resistance.
