Is it normal to cry laughing?
Yep.Totally normal
Yes—laughing hard enough to cry is totally normal. Some people tear up when they laugh, especially when they’re really amused or trying to catch their breath.
Your eyes can water when you laugh because the muscles and pressure changes around them can trigger tears. And sometimes you’re simply laughing so hard that your body’s emotional and physical reactions spill over into crying.
It happens to lots of people, though some are much more prone to it than others. If you mean you suddenly start crying or laughing uncontrollably in situations where it feels out of your control, that’s a different thing worth paying attention to; otherwise, laugh-cry away.
