The “Rule of 200” suggests: “To the typical sauna bather, a sauna is most comfortable when the combination of degrees Fahrenheit plus Relative Humidity is 200 or less”.
Example: | Room temperature is 145 F. | 200 - 145 = 55 |
There could be up to 55% humidity in the room before it becomes uncomfortable for the user. If temperature goes up the humidity level will need to come down to be comfortable for the user.
