When you’re feeling under the weather, deciding whether to push through a workout or rest can be tricky. While staying active is key to overall health, exercising when sick can sometimes do more harm than good. So, should you hit the gym or hit the couch? Here’s what you need to know.

 

The “Neck Rule”: A Simple Guide

A general rule of thumb used by health experts is the "neck rule."

• Symptoms above the neck (runny nose, mild congestion, sneezing, sore throat) → It’s usually safe to exercise at a lower intensity.
• Symptoms below the neck (chest congestion, cough, fever, body aches, fatigue, stomach issues) → Skip your workout and rest.

While this rule is a good guideline, it’s important to listen to your body. Even if your symptoms are mild, pushing too hard could prolong your recovery.

When It’s Okay to Exercise

If you have a mild cold or allergies, light exercise may actually help. Activities like:

✔️ Walking – Gentle movement can open nasal passages and improve circulation.
✔️ Stretching or Yoga – Low-impact exercises can help relieve tension without overexerting your body.
✔️ Low-Intensity Strength Training – If you feel up to it, lifting light weights can keep you moving without overtaxing your system.

💡 Tip: If you start feeling worse during exercise, stop immediately and rest.

When You Should Skip Your Workout

There are certain symptoms that are clear signs to rest, not move:

❌ Fever – Exercising raises body temperature, which can make a fever worse.
❌ Body Aches or Fatigue – Your body needs energy to fight illness, not to power through a workout.
❌ Cough or Chest Congestion – Straining your lungs can lead to longer recovery times.
❌ Vomiting or Diarrhea – Dehydration is a risk, and exercise can make it worse.

💡 Tip: If you’re unsure, give yourself a "rest day" and see how you feel the next day before deciding to work out.

How Exercise Affects Your Immune System

Regular exercise strengthens your immune system, but intense workouts when sick can have the opposite effect. Strenuous exercise temporarily weakens immunity, making it easier for viruses to take hold. That’s why athletes who overtrain are often more prone to illness.

Moderate exercise, however, can actually boost immunity by:

✔️ Increasing circulation, which helps immune cells move through the body.
✔️ Reducing stress hormones that can weaken immune defenses.
✔️ Improving sleep, which is essential for recovery.

💡 Tip: Aim for moderate movement when sick instead of high-intensity workouts.

Tips for Working Out Safely When Sick

If you decide to exercise while under the weather, keep these tips in mind:

✔️ Lower the intensity – Swap out HIIT workouts for gentle movement.
✔️ Stay hydrated – Your body loses fluids when fighting an infection.
✔️ Listen to your body – If you feel dizzy, exhausted, or worse after exercising, stop.
✔️ Avoid the gym – If you’re contagious, opt for a home workout to prevent spreading germs.
✔️ Get extra rest – Recovery is just as important as exercise.
