Is exercise good or bad when it is cold?

It's winter. Do you like fitness or fitness? Cold weather is not suitable for exercise.

First, don't exercise suddenly.

Before winter exercise, you should do some simple physical exercises to prevent ligament and muscle sprain.

Second, foggy days are not suitable for sports.

Practice has proved that fog is composed of countless tiny water droplets, which contain a lot of harmful substances such as dust and pathogenic microorganisms. With the increase of respiratory volume during exercise, the lungs are bound to inhale more harmful substances.

Third, it is not advisable to breathe with your mouth during exercise.

Winter sports should form the habit of breathing through the nose, because there is a lot of hair in the nose, which can filter the air and protect the trachea and lungs from dust and germs. In addition, the temperature is low in winter, and cold air can be warmed after entering the nostrils.

Fourth, exercise to keep warm can not be ignored.

Don't take off your coat as soon as you start exercising, and then gradually reduce your clothes after your body is slightly hot. After the exercise, you should immediately wipe your sweat and put on your clothes to prevent catching a cold.

Fifth, it is not advisable to exercise on an empty stomach.

In recent years, research shows that in addition to low blood sugar in the morning, human blood is sticky, coupled with low temperature, vasoconstriction and other factors, if you exercise on an empty stomach, you may die of hypoglycemia and heart disease. Therefore, middle-aged and elderly people should get up slowly in the morning and exercise after eating and drinking properly.

Sixth, it is not advisable to get up early and go out for exercise.

In recent years, science has confirmed that the air in the morning is not fresh, only around 4 pm is rich in oxygen negative ions. The concept of "smelling chickens and dancing" needs to be updated.

Pay attention to these, and it will probably be fine.
