Why Do We Blink So Frequently?

Blinking is like giving your eyes a quick hug. Every time you blink, your eyes get a little rest and stay wet so they don't feel dry or tired. Imagine if you had to keep your eyes open all day without any breaks, that would be exhausting!

Your brain sends signals to your eyes telling them to blink. These signals happen automatically, like a timer counting down in the background of your mind. You don't even have to think about it, your eyes just blink when they need a little break.
