Quick answers

How do nurses sleep after a 12-hour night shift?

Protect the first 2 hours after clock-out: block morning light, cut caffeine 8 hours before bed, and keep a consistent 7-hour dark window. The calculator above times it all for you.

What is the nurse “flip” from days to nights?

The 24–48 hour transition when switching rotations. An anchor nap makes it much easier — and the full plan shows a melatonin timing window if you and your clinician choose to use it.
