Sick Days: Train, Tweak or Rest?

Key takeaways

• Consistency beats perfection. A sniffle doesn’t cancel the week. Do a shorter session, drop the intensity (stop a few reps shy of failure), or move the workout to later in the week.

• Check your energy. Rate yourself honestly. At around 75%, do light training. At around 50% or with a fever, take 1–2 full rest days so a short illness doesn’t become a long one.

• Know illness from excuses. If you can still handle work and family, you can probably manage some movement. Watch out for stories like “I always get sick in winter.”

• Recovery counts as training. Mobility, an easy walk, a sea swim or the sauna all keep you moving without draining you.

• Eat simply when sick. Focus on hydration and plain, nourishing food. It’s fine if protein drops when your appetite does, but avoid junk food, which slows recovery.

• Prevention is the real win. Poor sleep plus high stress is the biggest route to getting ill. The basics you already do (sleep, whole foods, daily movement) are what build a resilient immune system.
