If you work nights, you already know the trap.

You finish at 7. The sun is up. You tell yourself you’ll sleep “a little extra” on your stretch of days off and even it out.

That is why you feel hungover on Tuesday.

Your body does not average sleep across a week. It tracks the last two nights. Two 12-hour nights, then a Saturday sleep-in until 1pm, then back on Sunday night, is not recovery. It is a second jet lag you gave yourself.

What actually works on a hospital schedule is boring:

• Pick a sleep window that can survive both work nights and off nights. Same start, even if the end moves.

• Get home and get dark within 30 minutes. Not “after I unwind.” Unwinding is the thing that steals the window.

• Do not use days off to flip fully to a day schedule unless you have 4+ days off. Two days off is not enough to flip and flip back.

The nurses who last on nights are not the ones with better genetics. They are the ones who treat sleep like a shift they cannot trade.

If you want the 30-day version of this for rotating and overnight units, it is in Steadier Sleep Solutions.
