190 degree sauna vs 190 degree hot tub

858 views

Explain it to me like I’m five.

How can I sit in a 190 degree sauna for 20 minutes and be comfortable but any hot tub higher than 104 degrees is unsafe, 150 degree water leaves burns on your skin.

Steam is about 0.58kg/m^(3). Liquid water is about 1000kg/m^(3). If you were to condense 1 cubic meter of steam (580 grams), you would end up with a little over 2 cups of water.

Consider the amount of energy that takes 2 cups of water, and then imagine all that energy spread over a cubic meter instead of just those 2 cups. You can see that the energy is *very* spread out. Not much of it is going to find its way into your body compared to if you were soaking in a hot tub.
