Infrared vs Traditional Sauna: Which Is Better for Health and Longevity?
Do infrared saunas detox you?
Traditional Finnish saunas (70–100°C) have the strongest evidence base — the large Finnish KIHD cohort linking 4–7 weekly sessions to roughly 40% lower all-cause mortality used traditional saunas. Infrared saunas run cooler (45–60°C) and heat the body more directly; early studies suggest similar cardiovascular effects at lower air temperatures, which suits people who find high heat uncomfortable. For health outcomes, the mechanism is the same — raising core temperature and heart rate — so the better sauna is the one you will use 3–4 times per week.
- Traditional sauna: 70–100°C, strongest longevity evidence
- Infrared: 45–60°C, more tolerable, promising but smaller evidence base
- Both raise core temperature and heart rate — that's the mechanism
- Aim for 3–4+ sessions per week, 15–20 minutes
- Consistency matters more than the type
Is an infrared sauna as good as a regular sauna?
Probably close, but not proven equal. The landmark longevity studies used traditional Finnish saunas. Infrared saunas raise core temperature at lower air temperatures and early research shows similar cardiovascular responses, but long-term outcome data doesn't exist yet.
How often should you sauna for health benefits?
The Finnish data shows a dose response: 2–3 sessions per week was good, 4–7 was best, with roughly 40% lower all-cause mortality in the highest group. Sessions of 15–20 minutes at tolerable heat.
Sauna sessions are sweat sessions — replace fluids and electrolytes afterward. ElectroSport and Fortune Delight are built for exactly that.

If you're choosing between an infrared cabin and a traditional sauna — at home or at the gym — this is the honest comparison: what each one does to your body, what the evidence says, and which one you should actually buy a membership for.
What the evidence actually says
Nearly all the strong sauna-and-longevity data comes from Finland's KIHD study, which followed over 2,300 men for two decades. Men using a traditional sauna 4–7 times per week had roughly 40% lower all-cause mortality and dramatically lower rates of fatal cardiovascular events and dementia than once-weekly users. These were traditional saunas at around 80°C.
Infrared saunas heat the body with radiant panels at lower air temperatures (45–60°C). Smaller studies show comparable increases in heart rate, core temperature and some cardiovascular markers. The honest summary: infrared looks promising and is more tolerable for many people, but the 20-year outcome data belongs to traditional heat.
Head-to-head comparison
| Factor | Traditional | Infrared |
|---|---|---|
| Air temperature | 70–100°C | 45–60°C |
| Longevity evidence | Strong (KIHD cohort) | Early / indirect |
| Tolerability | Intense heat | Easier for heat-sensitive people |
| Session length | 10–20 min | 20–40 min |
| Home cost | Higher (heater, ventilation) | Lower, plug-in cabins |
| Warm-up time | 30–45 min | 10–15 min |
Which one should you choose?
Choose the one you'll use three or more times a week. If high heat feels oppressive, an infrared cabin you'll actually sit in beats a traditional sauna you avoid. If you love the heat and want the protocol with the strongest evidence, go traditional. Either way, hydrate before and after — you can lose half a litre of sweat in a session.

Frequently asked
- Do infrared saunas detox you?
- Sweat contains trace amounts of some compounds, but the liver and kidneys do essentially all detoxification. The real benefits of any sauna are cardiovascular and heat-adaptation effects.
- How hot should a sauna be for health benefits?
- The Finnish studies used roughly 80°C traditional saunas. For infrared, sessions are longer at 45–60°C. In both cases, the goal is raising core temperature and heart rate to a tolerable level.
- Is it safe to sauna every day?
- For healthy adults, yes — the highest-benefit group in the Finnish data used the sauna 4–7 times weekly. Hydrate, avoid alcohol before sessions, and check with a doctor if you have heart conditions or are pregnant.
