How Hot Should a Sauna Be?
Understanding Sauna Types and Their Typical Temperatures
All saunas are created to be alike, and the "right" temperature depends on the type of sauna you're using.
Traditional Finnish Sauna (Dry Sauna): Heating is done with electric or wood, the temperatures generally vary between 150°F to 195°F (65-90°C). The lower humidity can provide higher temperatures without feeling suffocating.
Infrared Sauna: Uses infrared panels to warm your body directly, allowing a much lower temperature—typically 120°F to 150°F (50-65°C)—while still delivering the same relaxing and detoxifying effects.
Steam Room vs. Sauna: Steam rooms remain cooler (110-120°F). However, they feel hotter because of the 100 percent humidity.
Tips: If you're just getting started, you should try an infrared sauna for the first time. It's less strenuous and less painful.
The Optimal Sauna Temperature Range
So what is the ideal temperature for the sauna to be? For the majority of healthy adults:
Beginners: Begin with 150°F to 170°F (65-75°C) within a classic sauna.
Experimented Users: Temperatures as high as 185°F, or even 195°F (85-90°C), could be comfortable if you're used to extreme temperatures.
Infrared Saunas: Keep it to 120°F to 140°F for the best combination of sweat and comfort.
The most important thing is to be aware of the body's signals and never force yourself into temperatures that make you feel overwhelmed.
Factors That Influence Your Ideal Sauna Temperature
A variety of factors influence how hot your sauna should be. Personal Health plays a huge role: those who suffer from heart problems, high blood pressure, or pregnant women should consult with a doctor before going to the sauna.
Additionally, purpose matters—for muscle recovery, higher temperatures can be effective, while for relaxation, moderate heat is often sufficient. Time and tolerance also matter: the hotter the sauna, the shorter your session should be. Beginners should start at 10–12 minutes and increase gradually. Lastly, humidity can change your comfort level; splashing water over hot stones in a dry sauna can raise humidity and make the air feel warmer.
How to Measure and Control Sauna Heat
The ability to control temperature accurately is crucial for both safety and enjoyment. Always set up a thermometer inside the sauna so you can keep track of the heat. Adjust the heat source gradually, whether it's an electric stove, wood burner, or infrared panels.
In addition, a proper ventilation system helps maintain clean airflow and stable temperatures. Try not to open the door too often since it releases heat and reduces efficiency.
Safety Guidelines for Sauna Use

Although sauna bathing has many benefits, safety must always come first. Limit each session to 10–20 minutes, depending on the temperature and your experience level. Stay hydrated by drinking plenty of water before and after use, and avoid alcohol since it increases overheating risks.
Most importantly, listen to your body—leave immediately if you feel dizzy, nauseated, or unwell. Seniors, children, and those with medical conditions should opt for lower heat and shorter sessions to stay safe.
Health Benefits of Using a Sauna
When properly used, saunas can significantly boost overall health. They can help reduce muscle tension, relieve soreness after workouts, improve circulation, and promote faster recovery. Many users also find that sauna sessions encourage relaxation, reduce stress, and improve sleep quality.
Another important benefit is skin health—by opening pores and encouraging sweating, saunas help maintain clearer and healthier skin. However, extreme heat or long sessions can cause dehydration or fainting, so moderation is key.
Conclusion
The decision of how hot a sauna should be depends on the type of sauna, the purpose of use, and your personal comfort level. For most people, 150°F–180°F is an ideal starting point for traditional saunas, while infrared saunas deliver similar benefits at 120°F–140°F.
By following safety guidelines and adjusting temperatures gradually, you can enjoy the full range of sauna benefits—from relaxation and muscle recovery to improved circulation—without unnecessary risks.
