Six things to do about aerobic exercise in winter

1. Exercise should not be performed suddenly. Before exercise in winter, you should first do some simple exercises of limbs to prevent sprains of ligaments and muscles.

　　　　2. Exercise should not be performed in foggy days. Practice has proved that fog is composed of countless tiny water droplets. These foggy beads contain a large amount of harmful substances such as dust, pathogenic microorganisms, and other harmful substances. During exercise, more harmful substances will inevitably be inhaled in the lungs due to the increase in breathing volume.

　　　　3. It is not advisable to breathe with your mouth during exercise. In winter, you should develop the habit of breathing with your nose because there are many hairs in the nose, which can filter the air and prevent the trachea and lungs from dust and bacteria. In addition, the temperature in the cold winter is low, and cold air can be heated after entering the nostrils.

　　　　Is not to ignore keeping warm when exercising. You should not stand when starting to exercise. That is, take off your coat, wait until the body is slightly hot before gradually reducing your clothes. When the exercise is over, you should wipe the sweat off your body and put on your clothes immediately to prevent colds.

　　5. It is not advisable to exercise on an empty stomach. In recent years, studies have shown that in addition to low blood sugar, the human body's blood is sticky, coupled with factors such as low temperature and blood vessel contraction, if you exercise on an empty stomach, you may die of hypoglycemia and heart disease. Therefore, middle-aged and elderly people should wake up in the morning, eat appropriately and exercise after drinking water.

　　6. It is not advisable to get up early to exercise. In recent years, science has confirmed that the air in the early morning is not fresh, and it is only rich in oxygen negative ions at around 4 pm. The concept of "sniffing the chicken to dance" should be updated.
