The temperature in winter is very low, but many people still insist on exercising, but at the same time, they should pay attention to some minor problems.
First, exercise should not be carried out suddenly. Before the winter exercise, you should first do some simple limb movements to prevent ligaments and muscle sprains.
Second, fog should not be exercised. Practice has proved that fog is composed of numerous tiny water droplets. These mist beads contain a large amount of harmful substances such as dust and pathogenic microorganisms. As the breathing rate increases during exercise, the lungs will inevitably absorb more harmful substances.
Third, exercise should not use mouth breathing. Exercise in winter should develop a habit of breathing through the nose. Because there are many hairs in the nose, it can filter out air and protect the trachea and lungs from dust and germs. In addition, the cold winter temperatures are low and cold air can be warmed up after entering the nostrils.
Four, exercise should not ignore the warmth. When starting exercise, you should not take off your coat immediately, wait until your body heats slightly, and then gradually reduce your clothing. At the end of the exercise, you should wipe your sweat and put on your clothes immediately to prevent colds and colds.
Fifth, exercise should not be carried out on an empty stomach. In recent years, studies have shown that in addition to low blood sugar in the morning, the body's blood viscosity, coupled with low temperatures, vasoconstriction and other factors, if the fasting exercise may cause people to die due to hypoglycemia and heart disease, so the elderly get up in the morning To ease, appropriate meals, drinking water after exercise.
Sixth, should not get up early to go out exercise. In recent years, science has confirmed that the air is not new in the early hours of the morning. Only about 4 o'clock in the afternoon is it rich in oxygen negative ions. The concept of “sniffing chicken and dancing†should be updated.
