Is it normal to yawn when you wake up?
Yep.Totally normal
Yes—yawning when you wake up is completely normal. It’s a common part of shifting from sleep to being awake.
Lots of people yawn when they wake up, sometimes along with a big stretch. Your body is simply making the transition from sleep to alertness, and morning yawns don’t necessarily mean you didn’t get enough sleep.
So if you’re greeting the day with a yawn, you’re in very good company.
