You can run when you have a cold. Generally speaking, after a cold, people’s bodies are a little bit weaker, and they usually have symptoms such as fatigue and weakness or poor eating. At this time, most people do not have the strength to run, and many people do not run during the cold. If you still have the strength to run after the cold, it means that the symptoms are not serious, the cold is very mild, of course, will not affect anything, which means that the symptoms are very easy to control. So running after a cold is perfectly fine, and you don’t have to worry about the cold affecting running, or running affecting the symptoms of the cold.
