Can you train with a cold or fever? See when exercise is allowed.

Furthermore, physical exercise itself causes a mild inflammatory process and a temporary drop in immunity, which will also impair the body's ability to fight the fever's cause.

Another problem is that, during physical activity, our bodies produce a lot of heat. With a fever, the temperature is already above normal, and exercise will cause the body to heat up even more. This can lead to loss of strength, premature fatigue, and even more serious conditions, such as severe dehydration, dizziness, and fainting.

Therefore, in case of fever, the ideal is to not train and rest until the problem passes.

Flu and cold: training allowed (in moderation)

Although they may seem similar, the flu and a cold have different intensities. A cold is usually milder, with a runny nose, sneezing, and a stuffy nose. The flu, on the other hand, can bring fever, body aches, and fatigue. If you only have mild symptoms and no fever, you can exercise—on one condition: take it slow.

Light to moderate exercise helps release substances that increase well-being and can even speed recovery. This is a consensus among respected sports medicine institutions, such as the American College of Sports Medicine. But don't overdo it: instead of heavy weights at the gym, opt for a walk, a bike ride, or a lighter series.
