Yep. A problem with public saunas (outside Finland, at least) is that they lower the temperature (to, say below 80) in the misguided belief that this will make it easier for more people to stay longer inside.. which is the wrong way to use a sauna. A sauna should be hot enough that you'll go out when it starts feeling too hot (or hard), not so cold that you'll go outside when you're getting bored. With a hot sauna small children can leave after one or two minutes, some people leave after five, others after ten, and in any case go outside and cool down with a showre (or a lake..), then go back in.
