As you might imagine, too much yelling isn't good for your vocal cords. Whether it's too many rock concerts or frustration that needs a healthier outlet, chronic screaming will strain your vocal cords and can damage them over time.

What happens if you scream too long?

During speech, the cords vibrate and as they do, their edges bang against each other. Shouting, screaming or singing loudly for long periods can cause these banging edges to become swollen. If the vocal cords continue to collide too harshly, scar tissue in the shape of small hillocks (vocal nodules) may develop.
