Saunas have been used for centuries to promote relaxation, recovery, and a general sense of well-being. Today, most people are choosing between two main styles: traditional saunas (the classic hot-room experience) and infrared saunas (a newer option that uses light to warm the body more directly). While both can make you sweat, they feel very different—and the best choice depends on your comfort level, budget, and goals.
At a glance: the core difference
· Traditional sauna: Heats the air (via electric heater or wood stove). Your body warms primarily because you’re sitting in a hot environment.
· Infrared sauna: Uses infrared light to warm you more directly, typically at a lower air temperature.
1) Heat, temperature, and humidity
Traditional saunas commonly run hotter—often around 150–195°F (65–90°C). Depending on the style, they may be relatively dry (Finnish-style) or more humid if you pour water over hot stones to create steam (löyly). That high-heat, hot-air effect is the signature “classic sauna” feel.
Infrared saunas typically run at lower ambient temperatures—often about 110–150°F (43–65°C). They’re usually a low-humidity experience, but many people still sweat heavily because the heat is felt more on the skin and in the body rather than just in the surrounding air.
2) The experience: “hot room” vs. “gentler heat”
If you love the ritual of a traditional sauna—the intense heat, the blast of steam, the sharp contrast of stepping out into cooler air—traditional is hard to beat. Because the air is hotter, many people feel the effects quickly, but sessions may be shorter for those who are heat-sensitive.
Infrared tends to feel more tolerable for beginners. The air isn’t as scorching, so people who find traditional saunas overwhelming may be able to stay in longer. That said, the heat can still feel intense—just in a different way (more “radiant” and direct).
3) Potential benefits (and what to be cautious about)
Both sauna types are commonly used for relaxation, stress management, post-workout recovery, and better sleep routines. You’ll often see claims about detox, weight loss, or curing specific conditions—those claims are frequently overstated. Think of sauna use as a wellness practice, not a medical treatment.
· Traditional sauna: Has a longer history of use and more published research overall (especially around cardiovascular markers and frequent sauna bathing in certain populations).
· Infrared sauna: Research exists but is generally smaller and more mixed; many people choose it for comfort and consistency (it’s easier to tolerate, so they use it more often).
Safety note: Saunas increase heat stress and can affect blood pressure and hydration. If you’re pregnant, have cardiovascular concerns, take medications that affect heat tolerance, or have any condition where overheating is risky, check with a clinician first. Regardless of sauna type: hydrate, start with shorter sessions, and exit if you feel lightheaded or unwell.
4) Practical differences: warm-up time, space, and installation
Warm-up time: Traditional saunas often need more time to heat the room (commonly 20–45 minutes depending on the heater and ambient temperature). Infrared saunas may feel “ready” sooner because you’re being heated directly, though many still benefit from a short preheat.
Space and install: Traditional saunas (especially larger built-ins) can require more ventilation planning, higher-power electrical work, and moisture considerations if you use steam. Infrared units are often sold as plug-and-play cabins, which can make them simpler for homes or apartments—though you’ll still want to confirm electrical requirements and clearance.
5) Cost, maintenance, and longevity
Upfront cost varies widely for both types (from small personal units to custom builds). In general, traditional sauna builds can get expensive faster as size, heater capacity, and construction complexity increase. Infrared cabins can be more budget-friendly at entry level, but premium models can also be costly.
Maintenance: Traditional saunas may involve stone/heater upkeep and (for wood-burning setups) chimney/ash management. Infrared saunas rely on panels/emitters and electronics, so long-term maintenance can look more like appliance ownership. For both, regular wipe-downs, good ventilation, and letting the room dry out fully helps protect the wood and reduce odors.

Which one should you choose?
· Choose a traditional sauna if… you want the hottest experience, enjoy steam, and like the classic sauna culture/ritual.
· Choose an infrared sauna if… you prefer a lower air temperature, want a potentially easier home setup, or you’re more likely to use it consistently because it feels more comfortable.
· If you can, try both first: a single session will tell you more about comfort than any spec sheet.
Bottom line
Infrared and traditional saunas can both support a relaxing, restorative routine—the difference is mostly how the heat is delivered and how it feels to you. If you crave high heat and steam, go traditional. If you want a gentler-feeling session and a straightforward home option, infrared may be the better fit. Either way, start slow, hydrate, and aim for a routine you’ll actually enjoy.
