Saunas have been used for centuries to promote relaxation, improve circulation, and encourage detoxification. One of the most important factors that determines how effective and safe your sauna experience will be is the sauna temperature. Different types of saunas, such as traditional, infrared, and steam saunas, operate at varying heat levels. Knowing the right sauna temperature is crucial not only for comfort but also for safety.
In this article, we will explore the best sauna temperatures, how they affect your body, safety tips, and answers to common questions about sauna use.

What Is the Ideal Sauna Temperature?
The ideal sauna temperature depends on the type of sauna you are using. Traditional saunas typically operate at higher temperatures, while modern infrared saunas work at lower but deeply penetrating heat levels.
- Traditional dry sauna: 150°F to 195°F (65°C to 90°C)
- Steam sauna: 110°F to 120°F (43°C to 49°C)
- Infrared sauna: 110°F to 150°F (43°C to 65°C)
These ranges are considered safe and effective for most healthy adults. However, beginners may want to start at the lower end and gradually work their way up as they get accustomed to the heat.
Sauna Temperature and Health Benefits
The temperature of a sauna influences the health benefits you gain from your session. Higher heat usually triggers more intense sweating, while moderate heat allows for longer, more relaxing sessions.
- Improved Circulation
The heat causes blood vessels to expand, improving circulation and helping oxygen flow more efficiently. - Detoxification
Sweating at higher temperatures helps flush out toxins, salts, and heavy metals through the skin. - Stress Relief
Warmth at any sauna temperature promotes relaxation by reducing cortisol levels and encouraging the release of endorphins. - Muscle Recovery
Athletes often use higher sauna temperatures to relieve sore muscles and speed up recovery after workouts. - Skin Health
Sweating at optimal sauna temperatures helps clear pores, remove dirt, and promote a healthy glow.
Traditional Sauna Temperature
Traditional Finnish saunas are heated with wood stoves or electric heaters, bringing temperatures between 150°F and 195°F (65°C to 90°C). Some enthusiasts even push the temperature slightly higher, but caution is always advised.
At these levels, the body sweats heavily, the heart rate increases, and the metabolic rate gets a small boost. Sessions usually last between 10 and 20 minutes, followed by a cool shower or plunge.
Infrared Sauna Temperature
Infrared saunas are becoming increasingly popular because they operate at lower temperatures, typically between 110°F and 150°F (43°C to 65°C). Instead of heating the air, infrared saunas heat the body directly using infrared light waves.
This type of sauna provides similar benefits to traditional ones but allows people to stay inside longer since the heat is more tolerable. It is especially recommended for beginners, elderly individuals, or those who cannot handle high heat.
Steam Sauna Temperature
Steam rooms or steam saunas have lower temperatures, usually between 110°F and 120°F (43°C to 49°C), but maintain 100% humidity. The moist heat feels very different compared to the dry heat of a Finnish sauna.
Although the temperature is lower, the humidity makes it feel hotter and prevents sweat from evaporating, which can enhance detoxification and respiratory benefits. Steam saunas are excellent for clearing sinuses and supporting lung health.
Safe Sauna Temperature for Beginners
If you are new to saunas, it is best to start with:
- Infrared sauna: 110°F to 120°F (43°C to 49°C) for 15–20 minutes.
- Traditional sauna: 140°F to 160°F (60°C to 70°C) for 10–15 minutes.
- Steam sauna: 110°F (43°C) for 10–15 minutes.
Always listen to your body. If you feel dizzy, overheated, or uncomfortable, leave the sauna immediately and cool down.
How Long Should You Stay in a Sauna?
The ideal duration depends on the sauna temperature and your experience level.
- Traditional sauna: 10–20 minutes
- Infrared sauna: 20–45 minutes
- Steam sauna: 10–20 minutes
It’s important not to overdo it. Staying in too long can cause dehydration, dizziness, or even heat exhaustion. Hydrate before and after your session to stay safe.
Sauna Temperature for Weight Loss
Saunas do not directly burn fat, but sweating at higher sauna temperatures can help shed water weight temporarily. Regular sessions may also improve metabolism, reduce stress (which is linked to weight gain), and support a healthy lifestyle when combined with exercise and diet.
Sauna Temperature and Heart Health
Moderate sauna use has been shown to support cardiovascular health. Studies from Finland reveal that regular sauna bathing reduces the risk of high blood pressure, heart disease, and even stroke. However, individuals with heart conditions should consult a doctor before using high sauna temperatures.
Sauna Safety Tips
- Hydrate well before and after your sauna session.
- Avoid alcohol before sauna use, as it increases dehydration risk.
- Limit time inside the sauna based on its temperature.
- Cool down gradually after leaving the sauna with a shower or rest.
- Consult your doctor if you have health conditions such as heart disease, pregnancy, or low blood pressure.
Conclusion
The sauna temperature you choose depends on the type of sauna, your health condition, and your comfort level. Traditional saunas work best between 150°F and 195°F, infrared saunas at 110°F to 150°F, and steam saunas around 110°F to 120°F. Each has its unique benefits, from relaxation and improved circulation to detoxification and skin health.
By understanding the right sauna temperature and practicing safe habits, you can maximize the benefits while avoiding potential risks. Whether you prefer dry heat, moist steam, or gentle infrared warmth, the key is to find the temperature that best suits your body.
