Why Do People Lose Their Voices When They're Sick?

When you're sick, your voice goes on strike. Imagine your throat is like a busy highway, normally cars (sound waves) zoom through smoothly. But when you're sick, there's congestion and inflammation, it's like a traffic jam in the highway of your voice. That’s why it feels like your voice is missing or just doesn’t work right anymore.

When germs attack your throat, your body sends extra soldiers (white blood cells) to fight them off. This causes swelling and mucus, the traffic jam that stops your voice from traveling properly.
