Sleep With Your Bedroom Door Closed

A closed bedroom door can hold back fire, smoke, and toxic gases for 20 minutes or more — that's the difference between waking up and escaping, or never waking up at all. Fire research shows that rooms behind closed doors stay at survivable temperatures while open rooms reach over 500°C. This costs you nothing, requires no equipment, and works every single night. Just close your bedroom door before you go to sleep. If you have kids, close their doors too and make sure they know the family escape plan.
