Bathing with strangers in Oslo

Public bathhouses or saunas are known hotbeds of prostitution and homosexual promiscuity. Especially in large cities there is a certain locker room jock crowd of both genders.

Saunas are becoming increasingly popular worldwide, being an activity that promotes relaxation and health. Intense feelings of happiness have been reported shortly after enjoying a hot sauna and cold water, what is known in Japan as the “totonou”…

This one sounds like drugs and altered states of mind while getting naked.

Is this a frat house party? Steam for head cold or blocked sinuses, sure, but no, that's not what they want or what they're after.

The two-day gathering was held at a trendy resort outside Oslo, Norway, called The Well, where nude bathing is the norm and essential-oil-infused rituals, based on traditions like the German Aufguss, are held throughout the day. It took place on the eve of the International Sauna Congress, an event that attracts hundreds of sauna lovers and experts every four years.

I'm not sure if people think it's possible to actually “bathe” with their clothes still on, but it definitely sounds like these college students and/or professors are nude and they are taking lovers. I wouldn't be that scientific or formal about it.

As far as essential oils go, I wouldn't say they aren't smoking weed as well as getting drunk.

So with all that “anointing” and massages in the nude with bath oils, it is no wonder then that the Jews thought the name “Christiania” was indecent and insisted that the name of the city be changed to Oslo.
