Celebrity returns to having a schvitz for health?

Back in the day, it was common to enter a hot, steamy room, which was called a “schvitzbad” in Yiddish, and sit and sweat for your health for a short time.  Even Al Jolson was a fan of such activities.  Time and fashion passes, and few do this any more, other than the occasional sauna, which is usually dry heat.  Well, Selena Gomez talked about her way of having a schvitz, and how it makes her feel.  But is there a real benefit to it?  I joined a few physicians in sweating out the answer.
