Be careful when exercising with a cold: Doctors warn of dramatic consequences for the heart - even life-threatening danger. If symptoms are mild, a walk in the fresh air is good.
But if you have a fever, you should go to bed: If you get a cold or flu, people who do sports should take a break and pay attention to the body's signals. Anyone who is active despite symptoms such as fever, sore throat and cough puts extreme strain on their own immune system. This leaves the body with less energy for regeneration.
