Winter exercise is conducive to improving the body's ability to resist cold and freezing, enhancing disease resistance and tempering people's will. In order to receive good fitness exercise effect, we should pay attention to the following points:

1. Watch out for sports injuries. In winter, under the stimulation of cold, the viscosity of human muscles and ligaments will increase, which will reduce the elasticity and extensibility of muscles and the physiological activities of each joint. Therefore, before each exercise, we must pay attention to making full preparations to prevent injuries.

2. Breathe correctly. In winter, the climate is cold and windy and dusty. Therefore, don't take a big breath during exercise, but use the method of nasal cavity or nose-mouth mixed breathing to reduce the adverse stimulation of cold air on the respiratory tract.

3. Prevent colds and frostbite. In winter sports, clothes should be increased or decreased according to the change of outdoor cold. For the exposed hands, face, nose and ears, in addition to rubbing frequently to promote local blood circulation, proper amount of antifreeze, antifreeze and grease should be applied to prevent skin frostbite. In addition, the following points should be noted:

First, the exercise time is best arranged after dinner. It is not impossible to do morning exercises in winter, but because it is generally cold in the morning, the trees in the park have to be metabolized.

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 in afternoon exercise, 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 irregularity and lack of exercise, the body's resistance drops, and it is not only unconscious at work, but also prone to illness. 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.
