It’s the kind of sweat that sneaks up on you—slow, steady, and surprisingly pleasant.
You’re lying back in a wooden cabin, surrounded by soft red light. It’s quiet. Your heart is calm. You feel warm, but not overwhelmed. There’s no steam, no stifling heat. Just a deep, gentle warmth that seems to radiate from the inside out.
That’s not your typical sauna experience.
That’s infrared—and it’s turning the idea of sweating on its head.
A New Wave of Wellness
For decades, traditional saunas have been a staple of recovery and relaxation. Finnish bathhouses, gym locker rooms, and day spas worldwide have long relied on dry or steam saunas to provide a quick heat-induced detox and a moment of calm.
But infrared saunas? They work differently.
Instead of heating the air around you to high temperatures (often over 180°F), infrared saunas use panels that emit infrared light—a type of light you can’t see, but your body feels as radiant heat.
This penetrates deep into your tissues, warming you from the inside out, rather than the outside in.
The result?
A sweat that starts at a lower temperature (typically 120°F to 140°F) feels more comfortable and goes deeper.
The Science Behind the Sweat
Let’s break it down.
Traditional saunas rely on convection and conduction—hot air and surfaces heating your skin, which then induces a sweat response.
Infrared saunas, on the other hand, emit light in the far-infrared spectrum. This light penetrates the skin, warming muscle and connective tissue directly. Studies show this can increase blood flow, activate detox pathways, and support pain relief at a deeper level.
In one Japanese study, infrared sauna therapy showed reduced chronic pain and fatigue symptoms in patients with conditions like fibromyalgia. Another study in the Journal of the American College of Cardiology found that regular infrared sauna use improved blood vessel function and lowered blood pressure.
The lower heat also means longer sessions are possible, making it ideal for people who find traditional saunas too overwhelming or dehydrating.

Who Is Infrared Sauna Therapy For?
Infrared is perfect for:
It’s also excellent for cardiovascular health, immune support, skin rejuvenation, and even better sleep—all without the intensity of a steam-filled room.
The Bottom Line
Both types of saunas offer benefits, but infrared saunas open the door for more people to enjoy deeper, longer-lasting wellness experiences. You don’t need to tolerate overwhelming heat or dripping steam to get the therapeutic power of a sauna session.
With lower temps, longer sessions, and science to back the benefits, infrared is more than just a trend — it’s the next evolution in recovery.
