Why is there a heat lamp in hotel bathrooms?  One website said it's to warm up the bathroom before taking a shower.  Why?  Doesn't the hot water from the shower eventually warm the room?  Does anyone actually use these things?  Maybe I'm low-tech, but I've never even considered warming up the bathroom before I took a shower.  My parents definitely didn't have one of these things in their circa 1800s house. 

Wikipedia says a heat lamp is for "animal husbandry".  Hmm.  I don't follow. 

Oh I get it.  Gross. #entertainment
