Amid the lighthearted debates of everyday life—milk before cereal or vice versa, toilet paper roll facing the wall or forward—there’s a much more serious, yet often overlooked, question: should you sleep with the door open or closed? A choice that may seem trivial, but which hides a real domestic security issue.
Sleeping with the door open: a reflex that reassures… wrongly
Many people sleep with their door ajar , or even completely open. Why? To hear noises in the house , to let the air through , or simply out of habit or a sense of security . This is particularly true for parents of young children or anxious people.
But according to firefighters and fire prevention specialists , this practice increases the risks in the event of a domestic fire.
In case of fire, smoke kills faster than flames
When a fire breaks out, it is not the flames that spread fastest , but the smoke and toxic gases such as carbon monoxide.
These elements quickly infiltrate , invade rooms and can become fatal within minutes.
A closed door acts as a shield , slowing the arrival of heat, smoke, and gases. This gives you precious time to react, alert emergency services, and evacuate.
