Jogging will accelerate blood circulation, so that the coronary artery has enough blood to supply the myocardium, thus preventing various heart diseases. Through the movement of lower limbs, venous blood can be promoted to return to the heart and venous thrombosis can be prevented. What should I pay attention to when jogging? As a healthy sport, running has attracted a large number of enthusiastic fans, but have you found that many people's running postures are incorrect? Many people have either knee injuries or ankle injuries after running, most of which are caused by incorrect posture. Therefore, you need to master some correct running postures. Don't lean forward or backward. When running, keep your head, neck and spine in a straight line and avoid leaning forward or backward. Even when you accelerate, your head and body lean forward at the same time. Do you know that you can jog with a cold and fever?

Studies have shown that moderate exercise can reduce the number of days when cold symptoms appear by half. However, this does not apply to everyone, but it can be judged by a simple method-the neck rule. If you have cold symptoms above the neck, such as stuffy nose, itchy throat and headache, you can do moderate jogging, brisk walking or strength training. However, if the symptoms above the neck are more serious during exercise, you should stop exercising, otherwise it will be counterproductive and make the cold period longer. Once you have a fever, chest tightness and limb weakness, you should stop exercising and have a good rest. Need to be reminded that if headache is accompanied by chills and pain all over the body, it may be an early symptom of fever, so don't exercise any more.

It should be pointed out that a large amount of water must be replenished in time during exercise to prevent dehydration. In addition, for healthy people, upper respiratory tract infection is most likely to occur in a few hours after strenuous exercise. So, if you are running for 10 minutes, you'd better have a rest and keep warm. When exercising in the gym, wash your hands in time after using treadmills, barbells and other equipment. It is not advisable to jog with a cold and fever, otherwise it may aggravate the condition.
