ELI5: shift work sleep disorder
// explanation
Imagine your body has a special clock that tells you when to sleep and when to wake up. This clock likes the same schedule every day - sleeping at night and being awake during the day, just like the sun.

This makes it really hard to fall asleep when you need to, and you feel super tired when you're supposed to be working [2][5].
