Is it normal to cry when you laugh?
Yep.Totally normal
Yes—laughing hard can make your eyes water, and some people even tear up when something is especially funny. It’s a normal body response, not a sign that anything is wrong.
When you laugh intensely, your facial muscles tighten and can squeeze the tear glands, making your eyes water. Big laughter can also bring up strong feelings, so a few tears may come along for the ride.
It happens to lots of people, though some are more prone to it than others. If you’re only tearing up while laughing, there’s generally nothing to worry about.
