Many people who buy a portable sauna have wrong expectations about it. They expect the portable sauna temperature to reach extreme heat. Then, they get disappointed when they realize that this is not how a portable sauna works.
The truth is that a portable sauna can get fairly hot, but temperatures vary by type. Even though the temperature range is not as high as in a traditional sauna, it is still effective.

Portable Sauna Temperature: What to Expect

A portable sauna typically reaches temperatures between 110°F and 150°F.
However, this depends on its type. As you likely know, portable saunas can be steam-based and infrared. A steam sauna typically has a lower temperature range, going from 110-120°F on average. Infrared saunas tend to be a bit hotter, ranging from 110-150°F.
Traditional saunas are hotter than either portable option. Their temperatures range from 160°F to 212°F, although the optimal range is 158-194 degrees Fahrenheit.
Portable saunas don’t get as hot for several reasons. One of the biggest reasons is built-in limits, which are there for safe use at home.
Apart from that, they also have a more compact design and lower power, which also results in lower temperatures. However, make no mistake – a lower temperature doesn’t mean they have a weaker effect. The health benefits you can experience are still there, even if the temperature is lower.
Why Lower Temperatures Still Work

As mentioned, both steam and infrared portable saunas are weaker than traditional options. However, they can still get the job done. Steam saunas have a lower temperature but high humidity, thanks to vapor.
This makes them feel a lot hotter than they are, and causes intense sweating as soon as you step in.
Infrared saunas get a bit hotter, but they use dry, infrared heat. Thanks to the low humidity level, they have a slower heat buildup. This also allows for easier, longer sessions that are not as intense.
The reason this works is that both dry heat and wet saunas that use steam still cause the body to respond the same way. You will start sweating after stepping in, and your blood vessels will expand. This causes the heart rate to increase and circulation to speed up.
Note also that the infrared heats body directly, so it doesn’t need to increase the temperature of the air. Meanwhile, steam saunas trap the heat to increase the sensation.
What Temperature Should You Use?

Regardless of the type of sauna you decide to use, you should be mindful of the heat. Even though it is lower than in traditional saunas, it can still overwhelm you if you are not ready.
This is why those new to saunas are recommended to set the heat to 100-120°F for their first sauna session. You should stick to this heat while you are still new to the sauna experience. After a while, when you start getting used to it, you can go a bit higher to 120-140°F.
Higher temperatures, such as up to 150°F, are recommended for advanced users. But, even then, listen to your body and put comfort and relaxation over max heat.
Beginners should also start with shorter sessions and stay hydrated to avoid getting overwhelmed.
What Affects Portable Sauna Temperature

You might think that the portable sauna temperature is fairly straightforward. You turn it on, it gets heated, and that’s it. In reality, it is a bit more nuanced.
Sauna temperature is affected by multiple factors. Think room temperature, the size of the unit, and even body position. Then, there is heat loss, as heat will be leaving the tent, even if only slightly. This is why it matters to have zippers and seams that can prevent it as much as possible.
Finally, the biggest factor is the preheat time. Many make the mistake of going in too soon, before the sauna is ready. However, a preheat time is the most important part of your experience, even if you use infrared blankets.
Common Temperature Mistakes

Even though setting the temperature seems easy, new sauna users tend to make some common mistakes. For example, many find the experience underwhelming when setting the recommended temperatures.
Instead, they chase max heat too early, which can have a negative effect and rob them of health benefits. A portable sauna will not get as hot as traditional saunas, so it would be a mistake to compare them.
Another common mistake is skipping the preheat and entering the sauna too early. Others, however, stay too long in an attempt to “compensate” for lower heat. This can be dangerous, especially for those who don’t listen to their body and ignore how it actually feels.
Avoiding these mistakes is quite simple, but it takes the right mindset. Using a sauna for extreme experience or seeking detoxification, weight loss, and alike is the wrong approach. Use it for relaxation, raising your body temperature, and improved circulation.
A sauna – portable or otherwise – is not a shortcut for achieving health benefits. It is a habit and a process that takes a while, so take it slow and enjoy the experience.
FAQ
How hot are portable saunas compared to traditional saunas?
Portable saunas are not as hot as regular sauna, but that is by design. This makes portable sauna use safer in home conditions.
Is 120°F enough?
Yes, especially in steam saunas. While the temperature is not extreme, the humidity intensified the experience. Portable steam saunas operate at lower temperatures for that very reason.
Which feels hotter: steam or infrared?
Infrared is hotter, but steam saunas are typically more intense due to humidity. As a result, the steam sauna experience feels hotter, even if the actual temperature is lower.
Can you increase the temperature beyond limits?
No. Portable saunas have a built-in limiter for safety and to ensure prolonged performance. As a result, you cannot safely push them beyond their set limits.
Conclusion
Portable sauna temperature plays an important role in your overall sauna experience. However, it is not up to your personal preference – at least not at first.
Beginners should use them at lower temperatures. Even though it might feel underwhelming, they are still effective, and will make you sweat. Just because they aren’t making it hard to withstand the experience, it doesn’t mean that they don’t work.
The temperature in portable saunas is one of the situations where your perception might be different than actual numbers.
The experience might not feel as intense, but your body will feel it and react to it. In short, portable saunas are more than qualified to deliver health benefits you are after.
Trust the process and the technology and you will start noticing the difference in due time. The best you can do is learn more about it to know what to expect and what model to buy.
