Every year, adults catch the common cold two to four times, according to the CDC. And while tissues, tea, and rest are our usual go-tos, many wonder: is sauna good for a cold?
This guide explores what heat therapy—especially from saunas and steam rooms—does to your body when you’re sick. Can it ease your symptoms? Or does it make things worse?
We’ll answer common questions like:
- Is dry heat or steam better for congestion?
- Can using a sauna while sick help you recover faster?
- What does science say about using saunas for immune support?
Let’s dive into what really works—and what doesn’t—when it comes to sweating out your sniffles.
Understanding the Cold: Why You Feel Awful
What Is a Cold?
The common cold is a viral infection of your upper respiratory system, usually caused by rhinoviruses. It spreads easily and hits hardest when your immune system is already taxed.
Typical cold symptoms:
- Nasal congestion
- Coughing
- Sore throat
- Mild fever
- Muscle aches
- Fatigue
These symptoms come from your immune system’s response to the virus—not the virus itself. So anything that supports the immune system may help ease the illness.
The Sauna Solution: How Heat Affects Cold Symptoms
What Happens in a Sauna?
A dry sauna uses temperatures between 150–195°F (65–90°C) to heat the body. This induces sweating, increases heart rate, and raises internal body temperature.
This process mimics a mild artificial fever—a state that may stimulate the body’s immune response.
According to Dr. Andrew Weil, “Saunas can activate the immune system by creating a kind of artificial fever, which may help fight infections.”
Can a Sauna Help a Cold? Yes, But Be Smart
When a Sauna Helps
✅ Sinus relief: Heat helps loosen mucus and open nasal passages.
✅ Muscle relaxation: Saunas increase blood flow and reduce body aches.
✅ Stress relief: The endorphin boost from heat can improve mood and sleep.
✅ Immune support: A 2013 study from Finland found sauna users experienced 30% fewer colds annually.
When to Avoid the Sauna
❌ High fever: The heat can raise your core temperature dangerously.
❌ Dehydration: Saunas promote sweating, which can worsen fluid loss.
❌ Dizziness or weakness: A sign you should rest, not sweat.
Tip: Always listen to your body. If you feel lightheaded or worse after a session, stop immediately and hydrate.
Steam Room vs Sauna: Which Is Better for a Cold?
Steam Room Benefits
A steam room uses moist heat (around 110–120°F with 100% humidity). This can be more soothing for:
- Dry throats
- Tight chest
- Sinus congestion
Dry Sauna Benefits
A dry sauna is better if your symptoms are mostly muscle aches or fatigue without heavy mucus.
So, Which One’s Better?
- For nasal or sinus relief: ✅ Steam room
- For muscle aches & recovery: ✅ Dry sauna
- For feverish, dehydrated bodies: ❌ Neither—rest instead
How to Use a Sauna When You’re Sick (Safely)
Step-by-Step Guide
- Hydrate first. Drink a full glass of water before entering.
- Keep it short. Limit sessions to 10–15 minutes.
- Use a towel. Avoid spreading germs and stay dry.
- Take breaks. Step out if you feel dizzy or overheated.
- Cool down slowly. Don’t shock your body post-session.
- Rest afterward. Combine sauna use with naps and fluids.
Pro Tip: Add Eucalyptus
Eucalyptus oil in the steam can help open airways and reduce inflammation. Use a drop or two in a diffuser if your sauna allows it.
