What to know first
A traditional Finnish sauna uses hot air, relatively low humidity and water on hot stones to create a brief burst of steam — löyly. A steam room operates at a lower temperature but with air that is close to saturated. Sweat evaporates less efficiently there, so even the lower temperature can feel very intense.
An infrared cabin warms the body mainly through infrared radiation while the surrounding air remains cooler. It may feel pleasant, but it is not physiologically identical to a Finnish sauna. When research examines a particular temperature, humidity and device, its findings cannot automatically be treated as evidence for every kind of 'sauna'.

What the expert sources show
High humidity changes the heat load
A small comparative study showed different responses to dry and steam saunas. In a humid environment, sweat evaporates less efficiently, and therefore the air temperature alone does not describe the load on the body.
Open source · PubMedEvidence cannot be generalised across every type
A review of dry-sauna research included both Finnish saunas and lower-temperature forms of heat therapy. The authors highlighted varied protocols and the need for better studies, so health claims should always identify the method that was actually investigated.

How to use this in practice
- 01
Finnish sauna
Hot air warms the skin and body; water on the stones will increase humidity and the feeling of warmth for a short time. You can change the intensity with the amount of steam and the height of the bench.
- 02
Steam room
Moisture limits the evaporation of sweat. The sensation on the airways may be pleasant, but the steam does not cure asthma or infection.
- 03
Infrared cabin
Radiation warms the surface of the body in cooler air. The advantage may be tolerance, not proven superiority over other forms.

When to be cautious
Comparison by temperature only
Seventy degrees in dry air and fifty degrees at high humidity do not place the same heat load on the body.
Marketing shortcuts about health
Terms such as detox, fat burning or respiratory treatment require evidence for a specific method, not just the common word sauna.
Individual tolerance
With any type, stop if you feel dizzy, nauseous or develop palpitations, and replace lost fluids.
This article is educational and does not replace individual medical advice. If you have a chronic or unstable condition, are pregnant, or take medicines that affect blood pressure or temperature regulation, speak to your clinician.
06 — Summary
The key points
The heat dose consists of temperature, humidity, radiation, air flow, length of stay and the ability of sweat to evaporate. Finnish sauna, steam room and infrared cabin are therefore not interchangeable research interventions.
Choose an environment in which you can breathe well and relax. A quality experience is not a competition for the highest number on the thermometer.
Try a Finnish sauna in private
At Pixxla, you can control the steam intensity and set the pace of the entire ritual in complete privacy.
