Naps may impair immediate cognition via sleep inertia but enhance later alertness through parasympathetic activity; extends timing-specific nap research in healthy adults.
Does a 15-min or 45-min nap improve post-nap alertness and performance in healthy subjects?
Sleep inertia prolongs P300 latency immediately after naps, while parasympathetic predominance during naps may improve subsequent alertness 3 hours later.
Takahashi et al. (1998) studied this question.
