What Is the Science Behind Why We Sneeze?

Imagine your nose is like a fortress. When something tiny, like dust or pollen, sneaks in and starts causing trouble, the body sends out a signal to launch an attack, that's when you sneeze! It’s like a big explosion of air coming out of your nose to kick the intruder out. You might even feel it coming before it happens because your brain knows something is about to happen.
