Sauna Temperature: Find Your Ideal Heat Based on Science and Real Facility Data
People ask one question more than any other before their first visit: “How hot should a sauna be?” The answer depends on the type of sauna you choose, your experience level, and how your body responds to heat. In this guide we blend research-backed recommendations with real-world temperature readings from AllSaunas facilities so you can set realistic expectations, experiment safely, and find sessions that feel amazing—not overwhelming.
Throughout the article, you’ll see temperature ranges sourced from medical and sauna associations, plus unique insights drawn from AllSaunas listings. Use them as a starting point, then adjust with confidence.
Quick Answer: Sauna Temperature Ranges at a Glance
Sauna Type
Recommended Range
Experience Notes
Safety Ceiling
Traditional (Finnish/Dry)
70–100 °C (158–212 °F)
High heat with low humidity. Beginners often start around 70–80 °C.
110 °C (230 °F) absolute upper limit in most guidelines
Infrared
45–65 °C (113–149 °F)
Radiant heat warms the body directly. Feels gentler despite lower air temperature.
70 °C (158 °F)
Steam Room (Turkish/Hamam)
40–50 °C (104–122 °F)
High humidity boosts perceived heat; great for respiratory comfort.
55 °C (131 °F)
These numbers aren’t meant as hard rules—just a window into how venues tune their experiences. If you want to know what temperatures your local spas maintain, browse AllSaunas listings and filter by modality (infrared saunas, steam rooms, or all saunas) to compare the amenities and heat levels before you book.[6]
Traditional (Finnish/Dry) Saunas
Traditional or Finnish-style saunas operate with dry air (5–15% humidity) and high heat levels between 70–100 °C (158–212 °F). Finnish cohort studies published in JAMA Internal Medicine link regular dry-sauna use at these temperatures with cardiovascular and longevity benefits—provided users build tolerance slowly and stay hydrated.[3]
How to approach the heat:
Beginners: Start closer to 70–80 °C (158–176 °F) for 8–10 minutes. Sit on lower benches where air is cooler and exit if you feel dizzy.
Experienced users: Gradually experiment with upper-bench seating and longer sessions of 12–15 minutes, always cooling down in between rounds.
Aufguss & löyly: Pouring water on the stones briefly raises humidity and intensifies the heat. Follow staff guidance or posted schedules, and avoid essential oils unless the venue provides them—improper use can damage the heater.
Remember that even veteran sauna goers benefit from cooling breaks. Alternate with cold showers or plunge pools to return your core temperature to baseline before heading back in.
Infrared Saunas
Infrared cabins heat your body directly using near-, mid-, or far-infrared wavelengths, so the air stays relatively cooler—typically 45–65 °C (113–149 °F). Despite the lower thermometer reading, studies from the University of Eastern Finland and the Cleveland Clinic find that infrared heat still raises heart rate and induces sweating comparable to traditional saunas.[4]
Why some people prefer infrared:
The gentler air temperature allows longer sessions (20–30 minutes) without feeling overwhelmed.
People recovering from intense workouts appreciate the gradual warmth and potential muscle-relaxation benefits reported in small clinical trials.
Many infrared suites add color therapy, guided breathing, or meditative audio, making them approachable for first-timers.
Safety tips: Hydrate well, wipe sweat frequently, and stop if you experience headaches or excessive fatigue—especially if you’re new to heat therapy or have cardiovascular concerns.
Steam Rooms and Turkish Baths
Steam rooms, hammams, and Russian banyas pair modest temperatures (40–50 °C / 104–122 °F) with nearly 100% humidity.[1]
What to expect:
Respiratory relief: Warm, moist air can temporarily ease congestion, which is why some facilities diffuse eucalyptus or mint.
Shorter sessions: Because the heat index feels higher, most guests take 5–10 minute rounds before rinsing under cool water.
Slippery surfaces: Always wear sandals with grip and move carefully between benches and showers.
Steam etiquette mirrors sauna etiquette—shower before entering, sit on a towel where possible, and keep voices low to respect shared relaxation spaces.
Factors That Influence Your Ideal Temperature
Everyone’s heat tolerance is different. Adjust based on:
Experience level: Newcomers should start with shorter, lower-temp sessions. Seasoned enthusiasts can push higher settings with proper cooldowns.
Health status: Consult a physician if you have cardiovascular conditions, respiratory illnesses, or are pregnant. Some conditions require restricted exposure.
Hydration and nutrition: Arrive well-hydrated and avoid heavy meals or alcohol before your session. Even mild dehydration intensifies perceived heat.[5]
Session length: Ten minutes at 190 °F feels very different from ten minutes at 120 °F. Pair temperature with time and take ample rest between rounds.
Facility policies: Some venues limit self-led aufguss, bench positions, or session duration to keep everyone safe. Follow their guidance.
Safety Guidelines and Contraindications
Saunas are generally safe for healthy adults, but heed these guidelines:[2]
Recognize warning signs: Exit immediately if you feel lightheaded, nauseous, or your heart races. Cool down before attempting another round.
Time your sessions: Most medical sources, including the Mayo Clinic and WHO, recommend 10–15 minute intervals for beginners, extending to 15–20 minutes for acclimated users.[5][2]
Keep core temperature in check: Alternate heat with cool showers, outdoor air, or cold plunges. Many AllSaunas listings (filter by cold plunge) highlight contrast-therapy amenities.[6]
Skip alcohol before and during: Alcohol impairs judgment and hydration, compounding heat stress.
Special populations: Pregnant individuals, those with uncontrolled blood pressure, and anyone taking heat-sensitizing medications should seek medical clearance first.
Experimenting to Find Your Sweet Spot
Finding the perfect temperature is a process:
Start conservative: Choose the lower end of the recommended range for your sauna type and sit on a lower bench.
Log each session: Note temperature, duration, your perceived effort, and how you felt afterward. Wearables that track heart rate or skin temperature can help you spot patterns.
Adjust one variable at a time: Increase temperature or duration—not both simultaneously. Give your body time to adapt.
Mix modalities: Alternate between dry, infrared, and steam experiences over several visits to see which fits your goals best.
Use the space wisely: If a room feels too intense, move to a lower bench or closer to the door where air is cooler.
FAQ: Common Sauna Temperature Questions
Is 200 °F too hot? Traditional Finnish saunas often peak near 200 °F (93 °C) without issue for acclimated users. Beginners should start lower and only move toward 200 °F once they’re comfortable with shorter sessions at cooler temps.
Why does 120 °F feel hotter in a steam room than in a sauna? Humidity slows sweat evaporation, so your body can’t cool itself as effectively. The result: 120 °F steam can feel as intense as a 160 °F dry sauna.
How do I know if a sauna is infrared or traditional? Infrared rooms usually have panel heaters and operate below 150 °F. Check facility listings on AllSaunas or ask staff before booking.
Can I bring essential oils? Only if the venue allows it. Some operators supply specific blends for aufguss ceremonies; outside products may damage the heater or trigger allergies.
What temperature should I use at home? Follow the manufacturer’s guidance for your unit. Most home traditional saunas are designed for 170–190 °F, while home infrared cabins stay within 120–140 °F.

You just finished a 20-minute sauna session. You're drenched in sweat, your heart is pounding, and it genuinely feels like you just worked out. So how many calories did you actually burn?
The honest answer: fewer than you think, but more than doing nothing. A typical 30-minute sauna session burns between 40 and 80 calories depending on your body weight, sauna type, and temperature. That's roughly 1.5 to 2 times your resting metabolic rate — a modest but real increase.
