Saunas
Traditional, infrared and portable saunas, from tents to cabins, judged on materials, heat and evidence.
What we look for
We look for
- Heat that matches the research: most long-term studies are of traditional Finnish saunas at about 80 °C. Infrared and portable units run cooler, so a maximum should say whether it is a setting or measured air.
- Untreated, low-odor wood: the species (such as cedar, hemlock or spruce) named, any glue or finish stated, and ideally an independent cabin-air test.
- Safety certification: the heater and wiring listed by ETL, UL or CSA (or CE marked in Europe), with the listing naming the exact model, and no open recall.
- Materials that hold up to heat: for tents and blankets, the fabric and inner coating named, and no PVC.
- Low-EMF claims backed up: a named lab, report, instrument and distance, if the maker makes the claim.
We avoid
- Detox, weight-loss or “burn 600 calories” claims.
- Tents, blankets or pods that will not say what the inner layer is made of.
- Uncertified heaters and wiring, especially from marketplace sellers.
- Wood-fired tents with no carbon monoxide or fire-safety guidance.
