Many people leave their bedroom doors open at night because it feels more comfortable or allows better airflow. However, fire safety experts strongly encourage a different habit: **close your bedroom door before going to sleep.**

This small action can make a major difference during a house fire, when every second matters. Modern fires can spread much faster than in the past because many household items are made from synthetic materials that burn quickly and release thick, toxic smoke. In some situations, people may have only a few minutes to escape.

A closed bedroom door creates an important barrier between you and the fire. It can help slow the movement of flames, reduce the amount of oxygen reaching the fire, and keep the room cooler compared with a room exposed directly to smoke and heat.

One of the greatest dangers during a fire is not only the flames but also the toxic gases produced by burning materials. Keeping the door shut can help limit smoke entering the room, giving occupants more valuable time to wake up, assess the situation, and safely escape.

The simple habit known as **“Close Before You Doze”** costs nothing and takes only a few seconds. Along with working smoke alarms and a clear emergency escape plan, closing your bedroom door at night is one of the easiest steps you can take to improve fire safety.

A door left open may seem harmless during an ordinary night, but in an emergency, a closed door can become a critical layer of protection.
