Although 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. 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.
Be sure to replenish plenty of water 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.
Summer is the high incidence of air-conditioning colds. Don't turn the indoor air-conditioning temperature too low, and you can't stay in the air-conditioned room for a long time. When the temperature difference between inside and outside is too large, it is easy to cause a cold.
