Is it normal to cry when you yawn?
Yep.Totally normal
Yes, it’s normal to get watery eyes when you yawn. The muscles and pressure involved can squeeze tears onto your cheeks, even when you aren’t sad.
Yawning stretches and squeezes muscles around your eyes, which can put pressure on your tear glands or affect how tears drain. So your eyes may water, and sometimes the tears spill over—no emotional moment required.
