How hot does the sauna get?Updated 9 days ago

Unlike traditional saunas that heat the air around you, our FireLight® Sauna uses the proprietary FireLight® spectrum—featuring near (NIR), mid (MIR), and a little bit of far (FIR) infrared wavelengths—to heat your body from the inside. The result is a powerful blend of light therapy layered over heat therapy. 

And yes, you do sweat. 💧

What is the Air Temperature in the FireLight Sauna?

In our FireLight® Classic Sauna (4-bulbs), the air temperature typically ranges between 110-130°F—much lower than what you’d find in traditional saunas. However, the air temperature is not the most important factor when it comes to the effectiveness of our sauna.

The real measure of success is how much your body temperature increases. Our sauna is designed to raise your core body temperature by about 2-3°F and help you sweat out approximately a pound of water during your session. Because the near-infrared light penetrates deeply into your skin, it directly heats your body, so the air doesn’t need to be as hot. This makes our sauna sessions faster and more efficient compared to traditional saunas, which need to heat the air first before it can heat your body.

How Long Does a Sauna Session Take?

With our FireLight® Classic Sauna, you can achieve the full benefits of a sauna session in just 25-40 minutes. No sauna pre-heating is needed! 

SuperSauna: The Upgraded Experience

If you’re looking for an even more intense experience, our upgraded SuperSauna (Hearth® Quartet + Hearth® Trio) with 7 bulbs increases the air temperature to 130-150°F. This helps cut your session time in half—typically reducing your sauna session to around 10-20 minutes.

Sauna Temperature Customization

Our Hearth® Panels offer a customizable sauna experience. Each panel has individual switches, allowing you to adjust the intensity of your session. Whether you choose the standard Hearth® Quartet (1-4 FireLight bulbs) or the SuperSauna system (Hearth® Quartet + Hearth® Trio) with 1-7 FireLight bulbs, you can tailor each session to your preferences and needs.
