Dry Bulb Temperature: The Basic Sauna Temperature Reading
Dry bulb temperature is the air temperature measured by a standard thermometer that is not affected by moisture in the air. It's the number you see on your sauna thermometer - 180F, 200F, whatever your target is. It's the most common way people talk about sauna temperature, but it only tells part of the story. The same dry bulb temperature can feel dramatically different depending on the humidity level in the room.
What Dry Bulb Temperature Tells You (and Doesn't)
Dry bulb temperature measures the actual kinetic energy of the air molecules around the thermometer. It gives you a straightforward reading of how hot the air is. What it doesn't account for is humidity. At 190F with 10% humidity, sweat evaporates quickly and your body cools itself efficiently. At 190F with 40% humidity, evaporation slows down and the effective heat load on your body is much higher.
This is why experienced sauna users pay attention to both temperature and humidity rather than temperature alone. A 170F sauna with a fresh ladle of water on the stones can feel more intense than a 200F bone-dry sauna.
Where to Mount Your Thermometer
Dry bulb temperature varies significantly within a sauna room. The ceiling can be 20-40F hotter than the floor. Standard practice is to mount your thermometer at head height while seated on the upper bench, since that's the temperature your body actually experiences during a session. Mounting it too high gives readings that overstate the temperature you're feeling. Too low and it understates it.
Dry Bulb vs. Wet Bulb
While dry bulb temperature uses a standard exposed thermometer, wet bulb temperature wraps the sensor in a wet wick. The evaporation from the wick cools the thermometer, and the difference between dry and wet bulb readings tells you the humidity level. Together, these two measurements give you the complete picture of heat conditions in your sauna.
