Is it normal to cry after yawning?
Yep.Totally normal
Yes, it’s normal for your eyes to water when you yawn. The muscles and pressure involved can squeeze your tear glands a little.
Yawning can make the muscles around your eyes tighten and put pressure on your tear glands, so your eyes water. Some people tear up more than others, and it doesn’t necessarily mean you’re sad or actually crying.
If your eyes water at other times too, that can have plenty of ordinary causes, like irritation or allergies. But tears that come with pain, redness, or vision changes are worth getting checked.
