Something I don't really think about is whether my door is open or closed when I sleep, but after learning about this, I'll be changing how I think about it!

Before you go to bed do you make sure your door is open or closed?  Personally I've always left my door open for a couple reasons, one being it gets so hot in my room that I open the door to let the cool air in.  Two being my husband used to work nights, and I'd leave the tv on in the living room so I could see into there, but also so it looked like someone was up watching tv (at least in my mind anyway).

Well apparently I've been doing it wrong.  According to a video recently made by UL Firefighter Safety Research Institute you should sleep with the door closed. They have a campaign called "close before you doze" and to be honest the difference in the room with the closed door VS the room with the open door is pretty crazy!
