Saunas are 100°C?!

Boiling water temperature? Surely not.

It's largely to do with the ability of air, compared to something like water, to transfer heat - with air being relatively poor at it. Hence why comparing air at 100 deg C and water at 100 deg C isn't a good comparison. Water will trasnfer it's heat much more effectively than air, hence you can survive in dry air at 100 deg C, but not water at 100 deg C.

Same principle applies for cold water, being sumerged in to 10 deg C will feel much colder than being in 10 deg C air because it will much more efficient at transferring the heat away from your body.
 
The hottest I've been in my parents sauna was 110C at 40% humidity. Could only tolerate it for about 5mins and didn't even put water on the stones. Normally it's about 70-80C and putting some water on the stones will take it unto about 60% humidity which makes it feel stifling hot.

On a side note I was on Holiday in Spain once was in the Sauna at the hotel and a girl from Belgium came in also, she was in Bikini i was in just a towel she was well fit we got all hot and steamy in there..... and had passionate sex in my hotel room afterwards awsome best holiday with my parents ever i was only 16 at the time...LOL

pics or it didn't happen.
 
Got To love a good sauna, nothing else makes you feel as clean.

I usually prefer temps of 80-90C that is plenty for me. Although I do recommend if you ever get chance to try a wood sauna the heat is much less intensive and feels even better than the electric version. I have seen but never experienced a smoke sauna but am told that they are just awesome.
 
The one near me is 80 to 100 but often sits around 95. An 80c sauna feels pretty cold compare to a nice warm toasty 95. It takes me about 8-10 minutes (from going in dry) before the sweat is pouring off of me. I can sit in there from dry for about 20 mins, wet, 10 maybe 15 before it's too much
 
My gym has a steam room (~45C) and a sauna(~85C).

They both feel the same temp to me because of the humidity difference. Some people say the steam room feels a lot hotter.
 
100 degrees air temperature doesn't feel the same as having boiling water poured over you. There's some physics behind it probably :p

yep, air is a very poor conductor of heat, water is much better at transferring heat


for instance, when you pre-heat an oven to 200 degrees, everything in the oven is 200 degrees, the steel shelves, the air, etc - but when you go to open it to put something in, you hand doesnt get burnt by the 200 degree air, but it would get burn if you touched the 200 degree metal shelves :)
 
Never knew saunas exceed a 100 c mine hovers around 85-90 . So theoretically speaking if you had a large jug of water that is left in there for a long period of time wouldn't it boil then?

Depends on how hot the sauna gets. I think it would probably need to be higher than 100 degrees for the water to boil as that's an ambient temperature.
 
Under many circumstances, temperatures approaching and exceeding 100 °C (212 °F) would be completely intolerable. Saunas overcome this problem by controlling the humidity. The hottest Finnish saunas have relatively low humidity levels in which steam is generated by pouring water on the hot stones. This allows air temperatures that could boil water to be tolerated and even enjoyed for longer periods of time. Steam baths, such as the hammam, where the humidity approaches 100%, will be set to a much lower temperature of around 40 °C (104 °F) to compensate. The "wet heat" would cause scalding if the temperature were set much higher.

This is why ^

Its all about humidity
