Is it OK to exercise when you have a cold? As a general guide, mild to moderate physical activity is usually fine if you have a common cold. Symptoms of a common cold include a runny nose, nasal congestion, sneezing or minor sore throat. If you have a cold, you should consider reducing the intensity or length of your exercise.
Is it possible to sweat out a cold? There’s no way to cure a cold—or sweat it out. Breathing in warm, moist air can help alleviate cold symptoms, like congestion. Light exercise can increase blood flow, which also might help with congestion.
Will exercise help you fight a cold or infection? Exercise improves your overall fitness, which can help boost your immune system — the body’s defense against infections. Some studies show that “moderate intensity” exercise may cut down the number of colds you get.
