Neither sauna is better for everyone. Your choice depends on how you heat the body (air or radiation), how much heat you tolerate, how long you want to stay in and what you want from a session, whether that is relaxation, recovery or pain relief. At Sabaai Sabaai Massage & Spa we offer infrared sauna sessions for anyone who prefers gentler heat.
Key Takeaways
Infrared saunas offer gentler, more tolerable heat compared to traditional saunas, making them suitable for relaxation and mild physiological benefits.
| Point | Details |
|---|---|
| Heat intensity difference | Traditional saunas provide a stronger cardiovascular and core temperature response than infrared saunas, which are milder. |
| Session comfort and duration | Infrared sessions are perceived as softer and typically allow longer stays due to their cooler, drier air. |
| Health benefit evidence | While some benefits for cardiovascular health and pain relief are supported, many claims for saunas remain unproven or limited. |
| User preference factors | Infrared suits those sensitive to heat or seeking gentle, relaxing experiences, while traditional saunas appeal to those wanting intense heat. |
| Sabaai Sabaai approach | We offer infrared sauna sessions paired with massage for guests seeking gentle heat and relaxation. |

How do infrared and traditional saunas heat you differently?
A traditional sauna, often called a Finnish sauna, heats the air. A stove or electric heater warms a pile of rocks, and that hot air warms your skin first. Temperatures usually sit around 80–100°C, and humidity stays low until someone throws water on the rocks and a burst of steam rolls through. A systematic review of regular dry sauna bathing describes this style as short exposures at those high temperatures.
An infrared sauna works differently. Emitters in the cabin walls send out infrared radiation that warms your body directly, while the air stays cooler. The Mayo Clinic notes that these cabins typically run around 50–60°C, and that they may suit people who cannot tolerate the intense heat of a traditional sauna.
Humidity changes how hot a room feels. Damp air holds heat against your skin and makes the same temperature feel harsher. The drier, cooler air in an infrared cabin is why many people can stay in longer without feeling oppressed.
You will meet a few terms in other sources:
- Finnish sauna: the traditional high-heat, low-humidity air-heated sauna described above.
- Far-infrared: the longer-wavelength infrared band used in most infrared cabins.
- Waon therapy: a gentle, lower-temperature dry heat approach studied mainly in clinical settings, closer to infrared in feel than to a Finnish sauna.
- Hot water immersion: sitting in a hot bath, often used in studies as a comparison point.
What does the research say about body temperature and heart response?
The most direct head-to-head evidence comes from a 2025 randomised controlled trial that compared three passive heating methods: hot water immersion, a traditional sauna and a far-infrared sauna. It measured how each one changed core temperature, heart output and immune markers.
Core body temperature rose by 1.1°C with hot water immersion, 0.4°C in the traditional sauna and 0.0°C in the far-infrared sauna, so the infrared session did not measurably raise core temperature in that trial.
The heart told a similar story:
- Cardiac output rose by 3.7 L/min with hot water immersion.
- It rose by 2.3 L/min in the traditional sauna.
- It rose by 1.6 L/min in the far-infrared sauna.
- Only hot water immersion produced measurable inflammatory (IL‑6) and immune cell responses.
Put simply, the traditional sauna gave a bigger physiological push than the infrared one, and the infrared session was the mildest of the three. That does not make infrared worse. A gentler stimulus can be exactly what you want if you are after warmth and calm rather than a strong cardiovascular workout.
Keep this in context. A single trial cannot settle the question, and the wider literature is untidy. The review of regular dry sauna bathing found that studies vary widely in session length and temperature, and that the quality of evidence is mixed. A systematic review of infrared therapies for musculoskeletal conditions and chronic pain reaches a similar verdict: some improvements, but too much variation between studies for firm conclusions.
If you want the biggest heat stimulus, the traditional sauna delivers more of it. If you want a milder effect that you can repeat comfortably, infrared fits better.
How do the two saunas feel in a real session?
Most people describe an infrared session as softer. The air is not stifling, so you feel warmth soaking into your muscles rather than a wall of heat hitting your face. A traditional sauna feels more intense because the air itself is far hotter, and your breathing and heartbeat notice it quickly.
That difference shapes how long you stay. Traditional sessions tend to be short bursts, because the heat asks you to leave. Infrared users often stay longer, since the cooler air is easier to bear. Some operators also claim deeper tissue warming from the radiation, though the trial above suggests the whole-body effect is modest.
A few practical points change the experience:
- Humidity: a traditional sauna can swing from dry to steamy when water hits the rocks. Infrared stays steadily dry.
- Seating: traditional benches at different heights let you pick your heat, since hotter air rises. Infrared cabins are usually smaller and more uniform.
- Clothing: a towel or light swimwear works in both, but in an infrared cabin you sit close to the heating panels, so keep skin from touching them.
- Proximity: infrared warmth is stronger the nearer you sit to a panel, so shift position if one area feels too hot.
Pro Tip: Make your first visit short, and notice how your heart rate and effort feel before you stay longer.
Which health claims hold up, and which are still uncertain?
Saunas carry a long list of promises: deeper relaxation, relief from muscle aches, better circulation, cleaner skin, a stronger immune system. Some have decent support, others very little.
The stronger ground is cardiovascular and pain-related. A 2025 meta-analysis of non-acute passive heating trials found pooled benefits for vascular and cardiometabolic outcomes across heating methods, while stressing the variation between studies and the need for careful safety protocols. A review of far-infrared saunas and cardiovascular risk factors found limited to moderate evidence for some risk factors and chronic pain.
That same review concluded that the published evidence is limited when set against the broad claims many manufacturers make, which is a useful reminder to treat sales copy with care.
Where the evidence is thin or inconsistent:
- Detox: sweating does not prove toxins are leaving your body. We unpack this in our piece on infrared sauna detox.
- Weight loss: a lighter reading on the scale after a session is mostly water you will regain. Our article on infrared sauna and weight loss explains why.
- Skin: the claims are popular but the device science is more modest, as we cover in infrared sauna for skin.
- Cholesterol: results are inconsistent.
One more caveat: many studies look at repeated, regular use over weeks, not a one-off visit. A single session is best judged as a pleasant way to relax rather than a treatment.
Which sauna should you choose?
Think about what you actually want from a session. Infrared tends to suit you if you are sensitive to heat, enjoy longer and gentler sessions, or want warmth before or after a massage without the strain of very hot air; some also seek unique relaxation experiences such as yoga on a boat to complement their wellness routine. A traditional sauna tends to suit you if you like short, intense heat, enjoy the social ritual or simply love the Finnish style.
Run through this checklist before you decide:
- How much heat can you comfortably tolerate, and for how long?
- Do you have any heart condition, blood pressure issue or pregnancy to consider?
- How often do you expect to go?
- What can you reach easily, and what does each option cost you?
- Is your goal relaxation, recovery or a stronger physiological stimulus?
If you have heart disease, are pregnant or live with another significant medical condition, speak to a doctor before using either type of sauna. That advice applies to both, not just one.
How can you use a sauna safely?
Short, sensible habits make most of the difference.
- Before: drink water, skip alcohol and check with a doctor if you take medication that affects blood pressure or hydration.
- First visit: start with a short stay. Infrared may allow longer stays later, but begin cautiously with either type.
- Afterwards: cool down, rehydrate and rest. If you are pairing a session with a massage, our guide to timing a sauna before a massage covers the routine we use.
- Stop at once and seek immediate emergency care if you feel dizzy, get chest pain or become severely nauseous.
How we use infrared sessions alongside massage
We offer infrared sauna sessions and massage, and we find they work best for guests who want gentle heat rather than a hot, stifling room. If you want to try infrared with someone guiding you through it, a first session with us is an easy way to find out how it feels for you.

FAQ
Which is better, an infrared or a traditional sauna?
Neither wins outright. A traditional sauna gives a stronger heat stimulus, while an infrared sauna is gentler and easier to tolerate for longer. A 2025 comparative trial found the traditional sauna raised core temperature more than the far-infrared one.
What is the 200 rule for saunas?
The "200 rule" is a popular rule of thumb that adds the cabin temperature in degrees Fahrenheit to the humidity percentage. It is an informal guide, not a medical standard, and we do not have a source that defines it formally. Listen to your body and keep sessions short.
Is a sauna good for inflammation?
The evidence is limited. In the 2025 comparative trial, only hot water immersion produced a measurable inflammatory response, and neither sauna did. Larger studies are needed before saunas can be called an anti-inflammatory treatment.
What are the disadvantages of an infrared sauna?
Sessions can feel mild if you want intense heat, and the evidence behind many marketed benefits is still limited, as the far-infrared review notes. Check with a doctor first if you have a heart condition, are pregnant or take medication that affects blood pressure.
