Have you ever stayed up late talking to your friends while watching movies, or yelled for your teammates at a soccer match, or screamed at the top of your lungs walking through a haunted house? Maybe you woke up the next day with a hoarse, scratchy voice that you didn’t even recognize. In this episode, we talk to Dr. Jennifer Long, an otolaryngologist, about why we lose our voice when we yell or talk loudly.

Do you have a Moment of Um question that’s so good it makes you want to scream? Send it to us at BrainsOn.org/contact, and we’ll help vocalize the answer.
