Because after beginning of winter, the temperature will drop obviously, the air pressure will increase, the weather will be quite dry, the elasticity and ductility of our muscles, tendons and ligaments will decrease, and the viscosity of our muscles will also increase, so our bodies will become stiff and inflexible, and the ductility will also decrease. Therefore, if we exercise after beginning of winter, we should follow the corresponding health rules, otherwise we can keep warm and keep fit, and we won't hurt ourselves because of exercise.

Rule 1: Warm up fully before exercise.

Because a person's body will become stiff in a low temperature environment, it is easy to cause muscle strain or joint injury if you do not warm up sufficiently before exercise. Therefore, before the formal exercise, it is necessary to carry out "warm-up" exercises such as unarmed exercises and light weapons exercises, and the intensity of warm-up is appropriate to warm up the body and sweat slightly.

Rule 2: The thickness of clothes should be appropriate when exercising.

After beginning of winter, the temperature is very low, so you should put on thick clothes before exercise and take off your coat after warming up. After exercise, you should go back indoors as soon as possible, do not blow cold air, and wipe your sweat and change clothes to prevent heat loss caused by alternating hot and cold and catch a cold.

Rule 3: Adjust your breathing in time during exercise.

Because there are often sandstorms in winter, it is suggested that nasal breathing is the best exercise mode, and nasal inhalation and oral exhalation are also acceptable, but remember to inhale directly through your mouth. This is because the nasal mucosa can warm the inhaled air and reduce the stimulation of cold air to the respiratory tract to a certain extent; At the same time, nose hair can also effectively block bacteria, which can be called the "protector" of respiratory tract.

Rule 4: Keep the air circulating during indoor exercise.

Many people like to exercise indoors in winter. In order not to be warm, they will close the doors and windows. In fact, this will lead to our lack of oxygen, causing dizziness, nausea and other symptoms, so if you exercise indoors, you must keep the air circulating.
