When someone has a fever, physical activity should generally be approached with caution. Light physical activity, such as walking, might be okay if a person feels up to it, but more intense exercise or vigorous activity can stress the body and potentially worsen symptoms or prolong recovery.
Fever is often a sign that the body is fighting an infection, and during this time, rest is typically recommended. Rest helps the body focus its energy on healing. Engaging in physical activity when you have a fever can lead to increased heart rate, dehydration, and fatigue, which can make you feel worse overall.
It's essential to listen to your body. If you have a fever, it's usually best to rest, stay hydrated, and consult with a healthcare provider if symptoms persist or worsen.
