The Dry Sauna
A traditional Finnish dry sauna held at exactly 95°C: no range, no cold spots, and kept strictly dry, with no water on the stones, ever. Built obsessively to specification.
Bone dry, by choice
A traditional Finnish sauna does two things: dry heat, and löyly (water poured on the hot stones for a wave of steam). We split them. This room is the dry one, and we keep it strictly dry: no water, ever, no löyly, no bucket, no ladle. (Löyly lives next door, in our Aufguss sauna.) With nothing poured on the stones, the air stays crisp and clear, never the heavy damp of a steam room, pure dry heat, every time you sit down.
Dry heat you can stay with
Heat does its work by nudging your core temperature up a degree or two and holding it there, a mild, controlled heat stress. The limit is rarely the heat itself, it is comfort. Humid, steamy heat loads your body quickly but switches off its main cooling system, the evaporation of sweat, so you overheat and have to get out before you have banked much real time at temperature. Bone-dry air keeps that cooling running: your sweat evaporates the moment it forms, your skin stays manageable, and you can hold a steady, elevated core comfortably, at your own pace.
That is what saunamaxxing actually needs. The controlled heat stress that heat research links to your heat-shock response builds with time at temperature, and dry heat is what lets you put that time in and come back for more. We give you the tools: a 95° room that never sags, a cold plunge a step away, and a wool sauna hat that insulates the hottest part of you, your head, so it does not cook while your body takes on the heat.
How far you take it is your call, and your body has the final say. Saunamaxxing is only worth doing safely: keep your water up, never push past light-headed or giddy, and step out the moment anything feels off. The aim is the most comfortable time at temperature you can manage, never the most punishing. How to saunamax safely →
No cold spots. None.
Most saunas drift, so they quote a range. Ours was built to hold a single number. The heater, the stones, the wood, the airflow and the bench layout were all set so the heat lands evenly across every seat, no cold spots, corner to corner. Ninety-five degrees, steady, every time you sit down.
Why pin it at 95°
Saunamaxxing only works if the dose is real. A sauna that sags to 80° between guests isn’t giving you the heat you came for. By holding 95° precisely (the temperature range studied in long-term observational research), every session is the same consistent experience. In, settle into the heat, cool down in the plunge, repeat at whatever rhythm suits you. Dry, hot, simple.
Heat-shock proteins are part of your cells’ own stress response, switched on as your core temperature rises under controlled heat. Researchers have measured it directly:
- In a heat-chamber study, 30 minutes of whole-body heat in a 73° room raised heat-shock protein 72 by around 49%. (Iguchi et al., 2012)
- Finnish sauna sessions have been shown to lift serum heat-shock protein 70 after a single bath. (2023 study, trained and untrained men)
These are small, early studies run at different heat doses than ours, and they describe a mechanism, not a promised result. What a pinned, bone-dry 95° gives you is the room to put in the comfortable time at temperature this research is built on.
