Wood-Fired vs. Infrared Sauna: What's the Difference and Which Is Better?
Infrared saunas are everywhere. Wood-fired saunas are something else entirely. Here's what the science and the experience actually say about the difference.
if you have been shopping for a sauna experience, or researching sauna health benefits, you have almost certainly come across this question: infrared or wood-fired? The answer matters more than most people realise.
What Is an Infrared Sauna?
Infrared saunas use electric infrared panels to heat your body directly, rather than heating the air around you. Because they operate at lower ambient temperatures, typically 50-65°C, and they are gentler to sit in. Many are marketed as more effective than traditional saunas because the heat "penetrates deeper into tissue."
They are widely available. You'll find them in spas, gyms, and home wellness setups across the Okanagan and BC.
What Is a Wood-Fired Sauna?
A traditional wood-fired sauna, like the one at Sweat Culture, uses an actual wood fire to heat a stack of stones, which then radiates heat into the room. Ambient temperatures reach 80–105°C. You can pour water on the stones to create bursts of steam. The fire provides warmth, light, ambiance, and smell that cannot be replicated by any electrical system.
This is how saunas have been used for thousands of years in Finland and across Scandinavia. The health research that underpins most of what we know about sauna, including the Finnish population studies, the cardiovascular research, and the longevity data, was conducted on traditional saunas, not infrared.
The Key Differences
Temperature. Wood-fired saunas operate at significantly higher temperatures (80–105°C vs. 50–65°C for infrared). This matters because the physiological responses we care about, including heat shock protein production, growth hormone release, cardiovascular adaptation, and deep sweating, are triggered by real heat stress. Your body needs to be challenged.
Infrared as a byproduct. Here is what most people do not know: traditional wood-fired saunas do produce near-infrared light as a natural byproduct of fire and radiant heat from hot stones. You receive infrared benefits in a wood-fired sauna, plus the additional benefits of higher ambient heat that infrared panels cannot match.
Steam. Pouring water on the stones in a traditional sauna creates löyly, a burst of steam that dramatically intensifies the heat experience and opens the airways. Infrared saunas cannot produce steam.
The research. The landmark studies on sauna and cardiovascular health (JAMA Internal Medicine, 2015), Alzheimer's risk reduction (65%), and all-cause mortality were conducted using traditional saunas. The infrared sauna research base is much thinner and the results less definitive.
The experience. There is no comparison. Sitting in a wood-fired sauna, hearing the fire crackle, smelling the wood and steam, feeling the dry or wet heat on your skin, is a sensory experience that an infrared panel in a wooden box cannot replicate.
So Which Is Better?
For health outcomes: wood-fired, based on the evidence. The research was done on traditional saunas. The temperatures are higher. The physiological stress is greater. The adaptation your body makes in response is more significant.
For convenience at home: infrared has its place.
For the real experience, the one that changes how you feel and how you think about wellness, there is only one answer.
At Sweat Culture, our wood-fired adventure trailer sauna reaches up to 105°C. You step out into Okanagan Lake. You come back to a fire. That is not a wellness product. That is the real thing.
