Sauna Heat Levels: Finding the Optimal Range

Saunas have been used for centuries as a means of relaxation and rejuvenation. However, not everyone is aware of the different heat levels that saunas can reach and what the ideal range is for optimal benefits. Understanding sauna heat levels is crucial to getting the most out of your sauna experience.
The heat level in a sauna can range from 60°C to 100°C, depending on the type of sauna and the preferences of the user. It is important to note that the higher the heat level, the more intense the sauna experience. While some people prefer higher temperatures for a more intense sweat, others may find it uncomfortable or even dangerous. It is essential to find the right range for your body and overall health.
In this article, we will explore the different sauna heat levels and their benefits, as well as how to determine the right range for your body. Whether you are a seasoned sauna user or a newcomer, understanding sauna heat levels is crucial to getting the most out of your sauna experience.

Understanding Sauna Heat Levels

Sauna heat levels are an important consideration when it comes to enjoying a sauna session. Different types of saunas have different heat levels, and it is important to understand the differences between them to get the most out of your sauna experience.

Infrared Sauna Heat Levels

Infrared saunas use infrared heaters to emit radiant heat, which is absorbed by the body. Infrared sauna heat levels typically range from 120°F to 150°F. However, the heat is more evenly distributed in an infrared sauna, so it may feel less intense than a traditional sauna at the same temperature.

Traditional Sauna Heat Levels

Traditional saunas use heated rocks to produce heat and steam, which raises the temperature in the sauna. Traditional sauna heat levels typically range from 150°F to 190°F. However, the heat is more concentrated in a traditional sauna, so it may feel more intense than an infrared sauna at the same temperature.

Steam Sauna Heat Levels

Steam saunas use a steam generator to produce steam, which raises the temperature and humidity in the sauna. Steam sauna heat levels typically range from 110°F to 120°F, with humidity levels ranging from 100% to 120%. The high humidity levels in a steam sauna can make the heat feel more intense than in other types of saunas.

When it comes to choosing the best sauna temperature, it ultimately comes down to personal preference. However, it is important to keep in mind that higher temperatures can lead to more intense sweating and potential dehydration. It is recommended to start with a lower temperature and gradually increase it as you become more accustomed to the heat.

In addition to understanding sauna heat levels, it is also important to consider the humidity level in the sauna. The ideal sauna temperature and humidity level can vary depending on the individual, but a relative humidity level of 10% to 20% is generally recommended.

Overall, understanding sauna heat levels and humidity levels can help you get the most out of your sauna experience.

Health and Safety Considerations

Saunas offer a range of health benefits, but it is important to be aware of potential safety concerns. This section will discuss both the health benefits and safety measures to keep in mind when using a sauna.

Health Benefits of Sauna

Saunas have been used for centuries for their health benefits. Some of the benefits include:

  • Improved circulation: The heat from the sauna causes blood vessels to dilate, which increases blood flow and oxygenation to the body's tissues.
  • Relaxation: Saunas can help reduce stress and promote relaxation by increasing the production of endorphins, which are natural painkillers produced by the body.
  • Detoxification: Sweating in a sauna can help rid the body of toxins and impurities.
  • Improved skin health: The heat and steam from the sauna can help open pores and improve skin health.

Safety Measures in Sauna

While saunas can offer many health benefits, it is important to follow safety measures to prevent injury or adverse health effects. Some important safety measures to keep in mind include:

  • Use a safety switch: Saunas should be equipped with a safety switch that shuts off the power if the temperature gets too high.
  • Be aware of medical conditions: People with certain medical conditions, such as heart disease, should consult with their doctor before using a sauna.
  • Pregnancy: Pregnant women should avoid using saunas, as the high temperatures can be harmful to the developing fetus.
  • Age: Children under the age of 12 should not use saunas, as their bodies are not yet fully developed and may be more susceptible to heat-related injuries.
  • Care: Saunas should be regularly cleaned and maintained to prevent the growth of bacteria and other harmful organisms.

By following these safety measures, individuals can safely enjoy the many health benefits that saunas offer.

Sauna Experience

The sauna experience can be different for everyone, but there are some common aspects that most people will experience. In this section, we will discuss what to expect before, during, and after a sauna session.

Preparation for Sauna

Before entering the sauna, it is important to prepare your body and mind. Here are some tips:

  • Hydrate: Drink plenty of water before entering the sauna to help your body sweat and avoid dehydration.
  • Shower: Take a quick shower to clean your skin and open up your pores.
  • Towel: Bring a towel to sit on and another to wipe off sweat.
  • Clothing: Wear loose clothing or a towel to allow your skin to breathe.

During the Sauna Session

Once inside the sauna, here are some things to keep in mind:

  • Sweat: You will start sweating within a few minutes of entering the sauna. This is normal and helps your body release toxins.
  • Relaxation: Try to relax and enjoy the experience. Some people like to meditate or listen to music.
  • Body temperature: Your body temperature will rise, and you may feel uncomfortable. If you feel dizzy or lightheaded, it is time to leave the sauna.
  • Core temperature: Your core temperature will rise, which can help improve circulation and relieve muscle and joint pain.
  • Comfort level: Pay attention to your comfort level. If you feel too hot or uncomfortable, it's okay to leave the sauna. How long should you stay in a sauna depends on factors such as your tolerance and the sauna's temperature, but a typical session often ranges from 10 to 20 minutes.

Post Sauna Session

After your sauna session, here are some things to do:

  • Hydrate: Drink plenty of water to rehydrate your body.
  • Shower: Take a cool shower to close your pores and cool your body down.
  • Relaxation: Take time to relax and let your body cool down. Some people like to take a nap or go to sleep after a sauna session.

Overall, the sauna experience can be a great way to relax and improve your health. Remember to listen to your body and pay attention to your comfort level. 


In conclusion, understanding sauna heat levels is crucial to enjoy a safe and effective sauna experience. The right range of heat levels can help you achieve your desired sauna benefits without risking any harm to your body.

It's important to remember that the ideal sauna temperature and humidity levels may vary depending on your personal preference, health condition, and experience level. Therefore, it's recommended to start with lower heat levels and gradually work your way up to higher levels as you become more comfortable with the heat.

When using a traditional sauna, it's recommended to keep the temperature between 150°F to 195°F and the humidity level between 10% to 20%. For infrared saunas, the temperature should be set between 120°F to 150°F, and the humidity level is not a concern.

Always remember to stay hydrated before, during, and after your sauna session, and never exceed your body's limits. If you experience any discomfort or health issues, stop the session immediately and seek medical advice.

By following these guidelines and understanding sauna heat levels, you can enjoy a relaxing and rejuvenating sauna experience while keeping your body safe and healthy.
