The effects of nighttime napping on sleep, sleep inertia, and performance during simulated 16 h night work: a pilot study
How Nighttime Naps Affect Sleep Quality, Grogginess, and Work Performance During a 16-Hour Night Shift
AI simplified
Abstract
Participants who took two naps at night showed superior performance compared to those who did not nap.
- and sleepiness were experienced directly after napping.
- Napping resulted in less sleepiness and fatigue from 06:00 to 09:00 compared to no naps.
- Response times on the Psychomotor Vigilance Test were faster in the nap groups.
- Participants in the nap groups performed more single-digit addition calculations than those in the NO-NAP condition.
- Performance in calculations was significantly better after the early morning nap (00:30-NAP) compared to the late-night nap (22:30-NAP).
