Bathhouses are back. Why you should be schvitzing.

Bathhouses are all about communal experiences, including shared hot and cold pools, saunas and steam rooms.

Bathhouses have a long history in different cultures, from the ancient Romans to Russian banyas.

They once served a very practical purpose, but today , they’re all about relaxing and recharging.

There may be some health risks associated with visiting bathhouses, including infections transmitted through sexual contact or the growth of fungi and bacteria in a hot, humid environment.

Don't eat or drink too much — or eat too little.

Stay hydrated, don't stay too long in “hot zones” and don’t be a hero.
