Infrared vs Traditional Sauna: Breaking Down the Key Differences & Benefits

Infrared vs Traditional Sauna: The Sauna Showdown

Saunas have been around for centuries, long before wellness influencers started sweating on Instagram and calling it detox. From the icy forests of Finland to the sleek home units glowing red in modern basements, they’ve stood the test of time for a reason. But these days, there’s a new debate heating up: infrared vs traditional sauna—which one actually works better?

If you’ve ever Googled this, you’ve probably fallen into a rabbit hole of vague health claims, conflicting advice, and maybe even someone promising you’ll reverse aging in 30 minutes. This article cuts through that.

We’re breaking down the real differences between infrared and traditional saunas—how they work, what they do, what the science actually says, and whether one is actually better for things like muscle recovery, circulation, or just zoning out after a long day.

Let’s settle this once and for all: Which sauna should you be sitting in—and why?

What Is a Traditional Sauna, Exactly?

Let’s start with the OG.

A traditional sauna uses either an electric heater or a wood-burning stove to warm the air inside an enclosed room—usually somewhere between 150°F and 195°F (65°C to 90°C). That hot air, in turn, heats your skin, gets your sweat going, and gives you that classic “I might pass out, but in a good way” feeling.

Humidity levels vary. A Finnish dry sauna? Bone dry. A steam-enhanced version? You’re getting humidity levels cranked to 40% or more. But regardless of style, the goal is the same: raise your core body temp, increase circulation, and force you to sweat like you just sprinted through a swamp.

This isn’t just about tradition either. Traditional saunas have been linked to benefits like improved cardiovascular health, stress reduction, and post-workout recovery—all with a very straightforward mechanism: get hot, sweat it out, cool down.

What Is an Infrared Sauna?

Now for the new kid on the block.

An infrared sauna doesn’t heat the air—it heats you directly. It uses infrared light (invisible but felt as heat) to penetrate the skin and raise your core body temperature from the inside out. Most infrared saunas run at a gentler 110°F to 140°F, which might sound underwhelming—until you’re 10 minutes in and sweating like you just finished a HIIT workout in flannel.

There’s no steam, no furnace, and no logs crackling in the corner. Instead, infrared panels—usually carbon or ceramic—emit far, mid, or near-infrared wavelengths. Some models let you toggle between those for the full buffet of radiant heat.

Infrared users often describe the heat as more tolerable, which makes it easier to stay in longer. But the real selling point? Research-backed benefits like improved heart health, muscle recovery, pain relief, and better sleep.

Infrared vs Traditional Sauna: Key Differences

So, how does infrared vs traditional sauna actually compare? Let’s line them up side by side:

Heat & Sweat

Traditional saunas crank the ambient air until your body reacts, fast. Within minutes, you’re drenched. Infrared, on the other hand, gradually raises your internal temp—so the sweat comes a bit slower, but proponents say it’s deeper and detoxifies at the cellular level (jury’s still out on the “detox” part, but the heat definitely does the work).

Time & Energy Efficiency

Infrared takes the lead here. It heats up quicker, uses less electricity, and doesn’t require complicated ventilation. That makes it easier to set up in a spare room without turning your house into a steam lodge.

The Experience

Some people want the hardcore blast of a traditional sauna—it’s a ritual, a sweat-fueled rite of passage. Others prefer the lower-temp, Netflix-friendly vibe of an infrared session. Neither is wrong; it just depends on whether you’re going full Viking or chilling with infrared wavelengths and a podcast.

Benefits of Infrared Saunas (According to Science)

Infrared sauna fans love to talk about detoxing, but let’s skip the pseudoscience and look at what research actually supports.

According to the Cleveland Clinic, infrared saunas may help with:

• Improved heart health: Mild infrared heat has been linked to better circulation and blood vessel function—similar to light cardio, without the treadmill.
• Pain relief: Several studies suggest infrared heat may reduce chronic pain in conditions like arthritis and fibromyalgia.
• Muscle recovery: Athletes use infrared to aid post-workout recovery by increasing blood flow and reducing soreness.
• Stress relief and better sleep: Lower cortisol, better relaxation, deeper sleep—heat can help you chill out literally and mentally.

Unlike traditional saunas, infrared lets you stay in longer due to the lower temps. That extended exposure may offer deeper physiological benefits without the full-body sledgehammer of high heat.

Some small studies even suggest infrared sessions could help lower blood pressure and improve endothelial function—the stuff your cardiologist actually cares about.

Keep in mind: many studies are small, short-term, and sometimes industry-funded. The science is still growing—but it’s pointing in a direction that infrared isn’t just a wellness fad in disguise.

Traditional Sauna Benefits Still Hold Up

If you think traditional saunas are just old-school fluff, think again. The Mayo Clinic and other respected sources back up their benefits with real data—especially when it comes to long-term heart health.

A 20-year Finnish study showed frequent sauna use (4–7 times per week) was associated with a reduced risk of cardiovascular disease and all-cause mortality. Yes, sitting in a hot wooden box may actually help you live longer. Wild.

Traditional saunas also:

• Boost circulation and heart rate (like a light cardio workout)
• Help relax muscles and relieve joint stiffness
• Support mental clarity and stress reduction
• May improve skin through increased blood flow and sweat-induced exfoliation

One key advantage? Tradition. Many users find the dry or steamy heat more intense, more satisfying, and more meditative—like a hot yoga class without the awkward poses.

And while the temperatures are hotter and the sweat is more immediate, traditional saunas have decades of consistent research on their side. If you’re in it for cardiovascular perks, they’ve got serious street cred according to the Mayo Clinic.

So yes, while infrared has its high-tech appeal, the old ways still hold their own—especially if you want that classic deep sweat and heart-healthy ritual.

Safety, Risks, and That “Can Infrared Saunas Cause Cancer?” Question

Let’s address the sweaty elephant in the room: Are infrared saunas safe? And more specifically, can they cause cancer?

Infrared saunas use non-ionizing radiation—the same kind of heat you feel from the sun, just without the harmful UV rays. According to the American Cancer Society, non-ionizing radiation doesn’t damage DNA like ionizing radiation (such as X-rays), and there’s currently no evidence linking infrared heat exposure to cancer risk

That said, a few real safety considerations apply to both types of saunas:

• Dehydration: You’ll sweat—a lot. Drink water before, during, and after your session, or pay for it later.
• Overheating: Especially in traditional saunas where the air temp is much higher. Know your limits and step out if you feel lightheaded.
• Pre-existing conditions: If you’ve got heart issues, low blood pressure, or are pregnant, talk to your doctor first. No exceptions.

If anything, infrared might be safer for more people due to its lower temperature and slower heat buildup. It’s easier on the body while still delivering solid physiological effects.

Bottom line: both types are safe for healthy adults when used responsibly.

So…Which Sauna Is Better? Depends on Your Goals

If you’re hoping this ends with a clear winner, here’s the reality: infrared vs traditional sauna isn’t a one-size-fits-all battle. It’s more like choosing between lifting weights or going for a run—they both work, they just hit differently.

Go with a traditional sauna if you:

• Want that intense, immediate heat experience
• Prefer a more social or meditative ritual
• Are chasing cardiovascular benefits backed by decades of data

Opt for infrared if you:

• Prefer lower heat but longer sessions
• Want a compact, energy-efficient option at home
• Are recovering from workouts or managing chronic pain

Some people even rotate both—traditional for the deep detox blast, infrared for chill weekday recovery.

And if your main goal is recovery after exercise, the timing of your sauna matters too. Should you go before or after your workout? That’s a whole other debate—and yes, we covered it.

Check out our guide on Sauna Before or After Workout to make sure you’re not sabotaging your gains or wasting your sweat.

Ultimately, the best sauna is the one you’ll actually use. The goal isn’t to chase trends—it’s to support your body in a way that works for your lifestyle.

Final Thoughts

So, what’s the real difference in the infrared vs traditional sauna showdown? In short: how they heat you, how they feel, and how they fit into your routine.

Both help you sweat. Both support circulation, recovery, and stress relief. But whether you want the old-school, heart-pounding heat of a traditional sauna or the gentler, deep-penetrating warmth of an infrared one depends entirely on your goals—and how much you’re willing to sweat through to get there.

The key isn’t chasing the trendiest option. It’s choosing the sauna that you’ll actually use consistently.

Now go sweat smart.
