Most people assume one sauna type is simply better than the other, but the real answer depends on your health goals, heat tolerance, and how often you realistically plan to use it. The research behind each option is more nuanced than most wellness content suggests.
Choosing between the two is less obvious than it seems, and the science tells a more layered story than most people expect. Before committing to a purchase, browsing a side-by-side breakdown of top-rated home sauna models can help frame what features actually matter. By the end of this guide, you will know exactly which sauna fits your lifestyle and why.
How They Heat Your Body Differently
The core difference between these two saunas has nothing to do with size or aesthetics. It comes down to how heat reaches your body in the first place.
Traditional saunas heat the air around you to temperatures between 176°F and 200°F, and your body gradually warms as a result of the hot surrounding air. Infrared saunas work differently by using light waves to heat your body directly, skipping the hot air entirely and operating at a much lower range of 113°F to 140°F.
That gap is bigger than it sounds. Even at its lowest setting, a traditional sauna runs more than 30 degrees hotter than an infrared sauna at full heat, and that single difference shapes everything from session length to who each type realistically works for.
What the Science Actually Supports
Traditional Saunas Have Decades of Research Behind Them
Most of the strongest long-term evidence on sauna use comes from studies on traditional Finnish-style saunas specifically. Large observational studies following thousands of Finnish men over several decades found that using a sauna four to seven times per week was associated with significantly lower risks of cardiovascular disease, sudden cardiac death, and all-cause mortality.
One study tracking over 2,300 men for nearly 20 years found that frequent sauna users had a 40% lower risk of dying from any cause compared to those who only went once a week. Beyond heart health, separate research linked regular use to reduced risk of dementia, high blood pressure, and Alzheimer's disease.
These studies cannot prove direct cause and effect, but the consistency of the findings across multiple large, long-running studies is difficult to dismiss.
Infrared Saunas Are Supported by Promising Early Evidence
Infrared research is newer, and the studies are smaller, but the results are still worth noting. Clinical trials found that infrared sauna sessions helped reduce pain and stiffness in patients with rheumatoid arthritis, improved fatigue in people with chronic fatigue syndrome, and supported heart function in those with chronic heart failure.
One clinical trial involving 93 adults diagnosed with major depressive disorder found that a single infrared heat session produced improvements in depression symptoms lasting up to six weeks. That is a notable finding for a single session, though larger studies are still needed to confirm it.
The honest takeaway is that traditional saunas currently have the deeper evidence base, but infrared saunas are not without meaningful clinical support, particularly for chronic pain and fatigue-related conditions.
Benefits Both Types Deliver
Despite their differences, both sauna types trigger several of the same beneficial responses when used consistently:
- Improved circulation and cardiovascular function through repeated heat exposure
- Endorphin release that supports mood and sense of well-being after sessions
- Sweating that may help the body excrete certain heavy metals and environmental compounds
- Stress adaptation through mild, repeated heat exposure that activates cellular repair
These shared benefits reinforce one important point: consistent use of either type will likely outperform occasional use of whichever one looks better on paper.
Choosing the Right One For Your Situation
Heat Tolerance and Comfort Matter More Than Most People Realize
Traditional saunas run hot by design, and for heat-tolerant users, that intensity is part of the appeal. For people managing chronic conditions, heat sensitivity, or those new to sauna use, sustaining sessions long enough to get meaningful benefit can be genuinely difficult at those temperatures.
Because infrared saunas operate at lower heat levels, longer and more comfortable sessions become easier to maintain consistently. If intense heat is a barrier for you, infrared removes it without eliminating the core physiological benefit of raising your body temperature.
Cost and Setup Are Real Deciding Factors
Traditional saunas carry a higher upfront cost, with indoor models starting around $4,800 before installation fees. The 240-volt electrical requirement almost always means hiring a licensed electrician, adding anywhere from $1,000 to $5,000, depending on your home's existing setup.
Infrared models start around $2,500, and many plug into a standard 15-amp outlet, making them a far simpler and more affordable entry point for home use.
Who Each Sauna Actually Works Best For
A traditional sauna tends to suit people who:
- Prefer intense heat and the classic high-humidity sauna experience
- Want the most extensively researched form of sauna therapy available
- Have the budget and electrical capacity to support proper installation
An infrared sauna tends to suit people who:
- Are heat-sensitive or managing a chronic pain or fatigue condition
- Want an affordable, easy-to-install option for consistent home use
- Prefer longer, lower-temperature sessions that are easier to sustain
So Which One Should You Actually Choose?
Researchers and clinicians tend to agree on one thing: the sauna you use regularly will always beat the one you use rarely. A traditional sauna with stronger research behind it delivers little value if the heat pushes you out after five minutes.
For longevity and heart health specifically, traditional saunas hold the strongest evidence base. For accessibility, chronic condition management, and daily home use, infrared saunas offer a well-supported and more practical alternative for most people.
Either way, matching the sauna to your actual habits matters more than chasing the one with the best reputation. If you are still weighing specific models, a guide comparing highly rated options across both sauna types can help you land on the right fit for your space, budget, and health goals.
