Why might closing your bedroom door while you sleep save your life?
Sleeping with your bedroom door open might seem harmless or even necessary for those seeking air circulation or wanting to keep an eye on other family members. However, closing the door before bed has crucial implications for personal safety , emergency response, and even sleep quality. Here we explore the reasons why you should reconsider your nighttime habit.

First, closing the door significantly reduces the risk during a fire . According to the National Fire Protection Association (NFPA) , a closed door can contain the flames, reduce the spread of toxic smoke, and keep temperatures much lower inside a room. This not only provides more time to evacuate but can also mean the difference between life and death. During a fire, a room with the door closed can maintain a temperature of 37°C, while one with the door open can exceed 500°C, which is lethal in seconds.

Furthermore, closed doors act as barriers against smoke , one of the greatest dangers in fire situations. More people die from smoke inhalation than from the flames themselves, and a closed door can greatly reduce the amount of smoke entering the room. This simple action can protect your lungs and increase your chances of survival.
