A 20-minute exercise bout and a 90-minute nap improved episodic memory performance after 30 hours of wakefulness.
2

Both interventions resulted in higher hit rates compared to a control group, with exercise showing a 21% increase and napping a 23% increase.
3

Participants who napped reported less postintervention fatigue than those in the exercise and control groups.
4

EEG analyses indicated that exercise and napping engaged distinct neural mechanisms for memory encoding.
5

The study's limitations included the lack of a separate nap-control group and the potential mismatch in intervention durations.
