In sauna rooms, people spend time in conditions of air temperature over 90° C (194° F) with a relative humidity near 10%. However, if you stick your arm into liquid water that is at a temperature of 90° C (194° F), you will be severely burned in less than one minute. Give two reasons why people are able to spend time in a sauna, but are severely burned in water at the same temperature.

I have no idea why this is! Help?

You can cool yourself in a sauna by sweating. If you were wearing a coat in a sauna you would probably over heat and die.
