What is the Proper Safe Temperature Range for a Sauna?

Share This:

Throughout the centuries, saunas have held a beloved place in the cultural traditions of many nations around the globe, from the bathhouses of Turkey to the Scandinavian steam rooms. Historically recognized for their power to promote relaxation, their potential health benefits have, in recent years, also begun to be recognized. But, before you become the proud owner of your own sauna, it is crucial to understand how vital temperature controls are to ensure a safe, effective, and enjoyable experience. In this article, not only will we delve into safe temperature ranges for various types of saunas, but we'll also unpack some frequently asked questions we often receive.

Unraveling the heat of traditional dry saunas

When we imagine a traditional dry sauna, we think of the intensely hot, sweat-inducing atmosphere. These saunas typically reach temperatures between 70° and 100° degrees Celsius (158° - 212° degrees Fahrenheit) [1]. While such high temperatures can unlock a wealth of health benefits, not everyone can tolerate such heat levels.

Navigating the humidity of wet or steam saunas

Steam saunas, often known as wet saunas, typically operate at a lower temperature, generally simmering at around 40° - 50° degrees Celsius (104° - 122° degrees Fahrenheit) [1]. Despite the lower temperature, these steam-filled rooms can feel equally intense as their dry counterparts due to humidity levels that can reach as high as 100%.

Understanding the warmth of infrared saunas

Infrared saunas bring a different type of heat to the table. Rather than heating the air around you, these saunas use infrared heaters that directly heat your body. This direct application of warmth means that these saunas typically operate within a range of only 40° to 60° degrees Celsius (104° - 140° degrees Fahrenheit) [2].

Can a sauna be too hot for me?

This is a common question we receive, and the answer varies among individuals. It’s a matter of personal preference. According to the North American Sauna Society, they suggest a general temperature range for a sauna to be between 70° - 90° degrees Celsius (158° - 194° degrees Fahrenheit) [3]. However, nobody knows your comfort zone better than you! Your optimal sauna temperature can depend on various factors, including your age, health status, and personal preference.

The key is always to listen to your body. If you start to feel dizzy, nauseous, or overly uncomfortable, it's a signal that the heat might be too high for your tolerance. In such situations, it's prudent to exit the sauna immediately.

Beware of extreme heat exposure

The World Health Organization has issued warnings about the potential risks of extreme heat exposure, which can lead to heat-related illnesses such as heat exhaustion or even heat stroke [4]. This warning doesn't exclude the use of saunas. Hence, always remember to stay hydrated during your sauna use and to cool down thoroughly afterwards.

Balancing your sauna use

Establishing a safe sauna temperature is a balancing act between the type of sauna, your comfort, and safety guidelines. It's always sensible to start at a lower temperature before gradually increasing it, as long as you're comfortable and within the advised safety limits. And remember, the rejuvenating and calming sauna experience is much more about comfort than it is about endurance!
