Addicted to Saunas?

I regularly use the gym near St Jakob Stadium for normal gym work and spinning classes (note: here spinning classes are full of cyclists keeping fit during winter and not women bored of aerobics as is often the case in the UK). However, I've become mildly addicted to a Sauna afterwards. I have no problem with the normal european "no clothes" rule unlike some ex-pats over seem to have. I can hardly go a day without the refreshing feeling from 10 minutes in one now. Am I okay?
