How hot a Sauna should be?
A sauna is built around heat, airflow, bench height, and löyly. If you only read the thermometer, you are reading half the room. A traditional sauna runs 150–195°F, infrared runs 120–140°F, and steam rooms run 110–120°F; the practical sweet spot is 175°F.

What Is the Sweet Spot
for Sauna Heat ?
The best general setting is 175°F / 80°C in a traditional sauna. That point gives most users strong sweat, steady breathing, and room for löyly without turning the session into a survival contest.
Beginners should start lower. Experienced users can push higher for shorter rounds.
The Finnish rule is simple: heat until it feels good, throw water when it needs life, leave before pride takes over.
Best Sauna Temperature
for Health Benefits
Heat raises heart rate, widens blood vessels, and increases sweat output. That is the performance case.
Recovery comes from repeatable exposure, not one heroic session. A brutal sauna once a week is less useful than a controlled rhythm you can maintain.
If you’re taking sauna for weight loss, lets be honest. The quick drop in your weight after an aggressive session is mostly water in the form of sweat, its not fat burning.
For soreness, use heat after training when your breathing is calm. For sleep, use a lower setting and leave enough cooldown time.

Sauna Temperature Limits
Most users should treat 200°F / 93°C as the caution line.
Above that, session length shrinks and mistakes matter more. Add steam at that range and the room can turn hostile fast.
A public sauna at 240–260°F is not impressive. It is a liability problem.
Do not negotiate with those signs. The door is the safety device.
Leave immediately if you feel:

If you are pregnant, heat-sensitive, dehydrated, hungover or managing heart or blood pressure issues. Do not start there. Do not sit there for ego. Avoid these ranges:

Time is not the target. Recovery is the target.
A proper session uses heat, cooldown, rest, and repeat. That pattern works better than one long grind. If you need a clock to prove toughness, you are using the room wrong.
Your body gives better data than a wall timer.
SAUNA
Temperature in Celsius
Celsius makes sauna talk cleaner because Finnish-style heat is usually discussed that way.Still, numbers travel badly between rooms. A tight electric box and a large wood-fired cabin do not feel the same.
The better question is not “What does the dial say?” It is “How does the löyly land?”
Gym Sauna Temperature
Most gym saunas feel wrong for one of two reasons: too dry or poorly controlled.
Dry heat can show a big number on thermometer and still feel flat. Bad ventilation can make a moderate number feel stale.
Public rooms in gyms need conservative Sauna heat setting because users vary in age, hydration, health, and heat tolerance. A shared sauna is not your private test chamber. Do not crank the heater when people are already inside.
First comfort in the room matters less than basic safety.

Conclusion
A gym thermometer may be wrong by a wide margin. Bench height, wall placement, and door traffic distort the reading. If your gym sauna feels weak, sit higher, check airflow, and ask staff about the limit. If it feels dangerous, leave and report it.The best sauna temperature is the one that gives heat, breath, sweat, and control.
Anything beyond that is just cooking yourself.
