Sleep & Schedule
How many hours should I sleep after a night shift?
Aim for 7-8 hours, though 5-6 is more realistic. A solid 6-hour uninterrupted block is better than a fragmented 8 hours.
What is the best sleep schedule for 7pm-7am shifts?
Sleep 8:30am-3:30pm. Caffeine cutoff at 1am. Optional 20-minute nap at 5pm before your shift.
Should I sleep before or after my night shift?
Both. Sleep after each shift for recovery. Nap before your first shift of a block to start with less sleep debt.
Is it bad to sleep all day after a night shift?
No. Sleeping 7-8 hours after a night shift is not 'sleeping all day.' It is your night, just shifted in time.

Does melatonin work for shift workers?
Yes, in low doses (0.5-3mg). It helps signal 'sleep time' to your brain during daylight hours. It is not a sleeping pill. It shifts your body's sense of nighttime.
What supplements should night shift nurses take?
