Protecting episodic memory after sleep loss: Similar benefits of exercise and naps via distinct neural contributions.
Proceedings of the National Academy of Sciences of the United States of America·August 11, 2026·PMID 42566467
Why it mattersSleep loss impairs episodic memory formation, a critical function for safety-sensitive occupations. This study provides evidence that brief, accessible interventions—exercise or napping—can mitigate these cognitive deficits through different neural pathways, offering practical countermeasures when sleep is unavoidably restricted.
