A yawn is a big, deep breath you take when your body is feeling tired or bored! Scientists are not completely sure why we yawn, but they think it might help cool down your brain or wake it up a little bit. Yawning is a natural thing that everybody does!
When you yawn, you open your mouth wide and take in a big gulp of air. Your jaw stretches, your eyes might water, and you let out a big breath. Sometimes seeing a friend yawn makes you want to yawn right back — yawning is contagious!
Yawning is your body’s special way of telling you that it is almost time to sleep. If you are yawning a lot, stretching your arms or drinking water can help you wake up a little bit. Listening to your body when it yawns helps you know when it is time for rest!
