If you are into regular exercise, should you push through or pull back when you are ill? In an age where “no pain, no gain” often reigns supreme, the idea of skipping a workout can feel like failure. But according to fitness experts, exercising when you’re sick isn’t always brave. It could be risky. Knowing when to move and when to rest might just be the key to getting well faster.

Benefits of jogging or gym session?

Many believe that a quick jog or sweat session can “sweat out” a cold. But medical experts say otherwise. Dr Manjusha Agarwal, Senior Consultant in Internal Medicine at Gleneagles Hospital, Parel Mumbai, tells Moneycontrol: “Exercising during illness, especially with fever, fatigue or breathlessness, is not advisable. It strains the body, increases risk of injury, and slows recovery.”

Regular physical activity is great for immunity in the long run — but not when your body’s already in battle mode. When you're sick, especially with infections, your energy should go toward healing, not weights or cardio.

The ‘neck rule’ and when to skip the gym

So how do you know when it’s okay to move? The general rule of thumb is this: If symptoms are above the neck, think runny nose, mild sore throat or sneezing — then gentle exercise like walking or yoga may be safe. “If you're symptom-free from the neck down and don’t feel weak, a light 30-minute walk without exertion can be okay,” explains Dr Agarwal.

But that’s only if you’re not feeling worse after.

However, if symptoms are below the neck; fever, chest congestion, muscle aches, or general fatigue, then rest is not optional. It’s essential. Pushing through under these conditions can lead to complications, prolong illness, and increase your risk of dehydration or heart strain.
