Working out when sick depends on the type and severity of symptoms. Generally, if symptoms are "above the neck," such as a runny or stuffy nose, sneezing, mild sore throat, or light headache, it's usually safe to do light to moderate exercise at reduced intensity and duration. Activities like walking, yoga, or gentle cardio can be okay if you feel up to it. However, for symptoms "below the neck" such as chest congestion, hacking cough, fever, fatigue, vomiting, or body aches, it's best to rest and avoid working out until fully recovered. Exercising with a fever or severe illness can worsen symptoms or prolong recovery. The key is to listen to the body and consult a doctor if unsure.
