| Myth | Reality | | :--- | :--- | | Opening windows equalizes indoor/outdoor air pressure, preventing the roof from blowing off. | Tornado damage is caused primarily by , not pressure differences. Opening windows allows high-speed wind to enter the structure, increasing internal pressure and raising the roof from inside. |

Do not open windows. Keep them closed to maintain the structural integrity of your home as much as possible and keep flying debris outside. Forget the pressure equalization theory

Windows should be closed and remain closed during a tornado. The common myth that opening windows will “equalize pressure” and prevent structural damage is false and dangerous. All major meteorological and safety organizations (NOAA, FEMA, American Red Cross) strongly advise against opening windows.

Houses do not "explode" from air pressure changes. They are destroyed when high-capacity winds enter the building and lift the roof from the inside. Your windows cannot save your house, but staying

Use mattresses, thick blankets, or sleeping bags to protect yourself from flying glass.

: It was once believed that the extreme low pressure inside a tornado would cause a sealed house to "explode" as the higher internal pressure pushed outward.

WSMV 4, Nashville Show all Myth of "Pressure Equalization": It was once believed that opening windows would equalize pressure and prevent a house from "exploding" like a balloon. Scientific research has debunked this, proving that houses are destroyed by extreme wind and flying debris, not by atmospheric pressure differences. Risk of Roof Failure: Opening windows allows violent, high-speed winds to enter the home. This internal wind pressure pushes up on the roof while external winds create a lifting force on top, significantly increasing the chance that the roof will be ripped off the structure. Dangerous Projectiles: Leaving windows open invites flying debris and rain directly into your living space, creating a life-threatening environment for anyone inside. Time is Critical: Running to open or close windows wastes precious seconds that should be spent reaching your designated safe room. Safe Alternatives and Actions If a tornado is approaching, follow these priority safety steps: Move to an Interior Shelter: Go to the basement, a storm cellar, or a small, windowless interior room (like a bathroom, closet, or hallway) on the lowest floor. Create Barriers: Put as many walls as possible between yourself and the outside. Protect Your Head: Use pillows, heavy blankets, or a sturdy mattress to shield yourself from falling debris. Experts also highly recommend wearing a bicycle, motorcycle, or football helmet for critical head protection. Close Interior Doors: While you should not worry about exterior windows, closing interior doors can help reduce roof pressure by up to 30% and provides additional structural support. Wear Shoes: Always keep a pair of sturdy shoes in your safe area to protect your feet from broken glass and debris after the storm passes.
