Split Sleep for Night Shift
Split sleep for night shift uses a core post-shift block plus a pre-shift nap—both dark and timed—when one long daytime sleep is not realistic.
Split sleep for night shift divides rest into a core post-shift block plus a shorter pre-shift nap—common when seven to nine continuous hours are impossible. Both blocks need darkness and alarms that avoid sleep inertia before work.
Total duration should still approach weekly need; splitting is not permission to cut hours.

How long should a pre-shift nap be?
Ten to thirty minutes for alertness, or a full ninety-minute cycle if you have time and can wake without grogginess. Longer partial naps often cause sleep inertia on the job.
