We sell saunas. So take what follows with that in mind — and notice that we are about to talk you out of several reasons to buy one.
Infrared sauna marketing makes a lot of health claims. Some rest on real research. Some rest on research that studied something else entirely. Some rest on nothing at all. The difficulty is that all three are written in the same confident voice, so a buyer has no way to tell them apart.
This page does not give you a list of benefits. It gives you the method we use to judge a claim, so you can apply it to anything you read — including anything we write.
Why this page changed
An earlier version of this page made a large number of specific health claims without citing a source for any of them. That fell short of the standard we hold other brands to on our EMF and buying-mistakes guides, so we removed it rather than leave it up while we rebuild it properly. A fuller version, with every claim attributed and characterised, will replace this one.
We would rather show you an incomplete page than a confident one we cannot support.
How to read a sauna health claim
1. What was actually studied?
A great deal of the research cited in sauna marketing was conducted on traditional Finnish saunas — hot, humid rooms at roughly 80 °C, used repeatedly over years. Infrared cabins operate differently, at lower air temperatures, heating the body by a different mechanism. Findings from one do not transfer automatically to the other. When a brand cites a study, the first question is whether the intervention studied is the product being sold.
2. What kind of study was it?
A randomised controlled trial, an observational cohort, a small crossover study and a laboratory measurement are not interchangeable. Observational studies can show that two things occur together without establishing that one causes the other. Marketing copy routinely converts "associated with" into "reduces" — that single word change is where most overstatement happens.
3. Who was studied, and for how long?
Sample size, population and duration all bound what a result can mean. A finding in a few dozen participants over four weeks does not support a claim about lifelong outcomes in the general population.
4. Is the source recoverable?
A claim you cannot trace is a claim you cannot check. Named journal, year, and enough detail to find the paper is the minimum. A footnote that says "studies show" is not a citation.
5. Does the dose match?
Research protocols specify temperature, session length and frequency. If a claim comes from four sessions a week at a temperature your cabin does not reach, the claim does not describe your situation.
What we will not claim
- That an infrared sauna treats, cures or prevents any disease.
- That it removes toxins or heavy metals from the body.
- That it produces meaningful, lasting weight loss.
- That any specific number of calories is burned in a session.
- That findings from traditional Finnish sauna research apply unchanged to infrared cabins.
Some of these appear regularly in competitors' marketing. We are not saying every one is impossible; we are saying we have not seen evidence that meets the standard above, and we will not assert them until we do.
What we are comfortable saying
People buy saunas and keep using them. The reasons customers give us are usually straightforward: it is warm, it is quiet, it is twenty minutes where nobody needs anything from them, and it becomes a routine they look forward to. Those are honest reasons to own one, and they do not require a clinical claim to justify.
If you are considering a sauna for a specific medical reason, that is a conversation to have with your doctor — who knows your history, which we do not.
