Is it normal to laugh so hard you cough?
Mostly.Normal for most people
Yes—laughing hard can make you cough. The forceful breaths and throat irritation can set off a cough reflex, and it’s usually harmless.
When you laugh hard, your breathing gets choppy and your throat can feel dry or tickly. That can trigger a cough, especially if you already have a bit of irritation or mucus. Lots of people have this happen now and then.
