Cross ventilation

Cross ventilation is a fancy word for letting air flow through a room from one side to the other. You know how when you blow on something it moves? Well, air can move things when it moves too!

Cross ventilation can be really helpful when it's hot outside because it helps bring cooler air into the room. You can create cross ventilation by opening a window or a door on one side of the room and then opening one on the other side too. The air will flow through the room, like a breeze, and help cool things down.

Just like how you can make a tunnel with your hands to blow air in a certain direction, cross ventilation creates a little wind tunnel in your house that can help make it cooler and more comfortable.
