Why Do People Sometimes Lose Their Voices?

Sometimes people lose their voices because they shout or talk for too long. Imagine your voice is like a rubber band: if you stretch it too far, it snaps and can't make sound anymore. Your voice comes from a special part of your throat called the larynx, which has tiny muscles that help you speak. When these muscles get tired or swollen, they can’t work as well, so your voice goes away for a little while.
