Speaking of shower...There was this arab girl who said I can’t take shower until my period is over.

They apparently have this idea that if you shower especially with warm water during your period you’ll damage your inner organs. I thought she was joking at first but I got it confirmed from her landsmen they were saying omg you’re crazy you need to take care of your body don’t shower.
Now this led me to think maybe...Is this the reason why the Jewish men made their women leave the house when they are on their period...unclean?
