It's possible, yes. It's not likely unless someone is actually having a serious laughing fit, like the kind where you're laughing so hard you can't stand.
It's a little-appreciated frequent trigger. The study found that the most common symptom in patients with laughter-induced asthma was coughing, which generally starts within two minutes. The next most common symptom was chest tightness. For others, laughing hard will bring on asthma symptoms.
Yes, asthma can cause an asthma attack. I am an asthmatic and this has happened to me on more occasions than I can count. . . . . no so much when I am casually laughing but when I am hysterically laughing, I get short of breath and start wheezing to the point that I have to use my inhaler. Nothing really serious but it happens.
