ELI5: Why is your voice different (e.g. higher or less powerful) after being silent for a while?

You know how if you sit down for awhile, and then stand up, your legs feel like you’re stretching even though you’re just standing up? Muscles, both your leg muscles and your vocal chords, get ‘cold’ after not being used for awhile. So when you start using them again, they need warmed up and practiced with a bit before being ready for normal operation.
