Sauna or Steam Room? Here's What Science Says About Which One Is Better for Your Health

I recently joined a new gym, and one of the first questions I asked myself was, "Should I spend my time in the sauna or the steam room?"

If you've wondered the same thing, the good news is that you really can't make a bad choice. Both offer health benefits—but they aren't identical. Understanding what each does best can help you decide which one fits your goals.

The Sauna: Better for Your Heart

A traditional sauna uses dry heat, typically between 160°F and 200°F, causing your heart rate to rise in a way that's surprisingly similar to moderate exercise.

Research from Finland—where sauna use is practically a way of life—has linked regular sauna sessions (4–7 times per week) with lower risks of cardiovascular disease, stroke, dementia, and even all-cause mortality. While these studies don't prove that saunas alone cause these benefits, they consistently show strong associations.

The dry heat also promotes circulation, may help lower blood pressure over time, eases muscle soreness after workouts, and many people report deeper, more restful sleep after an evening sauna session.

The Steam Room: Better for Your Airways

Steam rooms operate at a lower temperature—usually 110°F to 120°F—but with nearly 100% humidity.

That warm, moist air can help loosen congestion, soothe irritated airways, and make breathing feel easier during a cold or allergy season. The humidity is also gentler on the skin, helping many people feel less dry than after a sauna.

Like saunas, steam rooms can relax muscles, improve circulation, and reduce stress, although there is less long-term research linking steam rooms to major health outcomes.

So Which Should You Choose?

If your primary goals are heart health, longevity, metabolic health, and recovery, the sauna probably has the strongest scientific evidence.

If you're dealing with sinus congestion, allergies, dry skin, or respiratory irritation, the steam room may be the better choice.

The best news?

You don't necessarily have to choose.

Many gyms allow members to use both. You might enjoy a 15–20 minute sauna after strength training on most days, then switch to the steam room when your muscles feel particularly tight or you're fighting seasonal congestion.

A Few Safety Tips

Whether you choose dry heat or steam:

• Stay well hydrated before and after.

• Limit sessions to 10–20 minutes, especially when you're starting out.

• Leave immediately if you feel dizzy, lightheaded, or nauseated.

• Avoid alcohol before or during heat exposure.

• If you have uncontrolled high blood pressure, significant heart disease, or are pregnant, check with your healthcare provider before using either.

My Recommendation

If I had access to both—as I now do—I would make the sauna my regular routine, aiming for three to five sessions each week after exercise, and use the steam room when I want respiratory relief or simply a different way to unwind.

Longevity isn't about finding one magic therapy. It's about consistently choosing healthy habits that help your body recover, your heart stay strong, and your mind relax.
