Nowadays, our lives are packed full of work, activities and chores and often, you feel ill but are well enough to go to work. But should you carry on exercising when you have a cold? It's difficult to tell whether exercising will make you feel better or worse, but there are signs that will help you make the right decision.
Exercising when you have a fever can cause your body temperature to rise even higher, potentially leading to heatstroke, according to sports-medicine specialist Lewis G. Maharam, M.D. A fever is a sign that your body is fighting a virus and exercise may cause that virus to invade the heart muscle or pericardium, the sac around the heart. When your body temperature is above normal, fluids are diminished by 5 to 10%, increasing the risk of dehydration and subsequent complications connected to the original illness.
