The afternoon hours are commonly associated with decreased motivation, productivity, and alertness. This midday dip does not depend on a prior meal, has been reported across cultures, and represents a physiologic diurnal nadir in our circadian rhythm. Throughtout history, napping behaviour has been utilized as a sleepiness countermeasure. Recent evidence shows that napping may also be an effective tool for performance enhancement. Studies have shown that naps are as effective for learning as a night of sleep. Similar to nocturnal sleep, sleep stages, electroencephalographic (EEG) power densities in naps have been correlated with specific types of memory consolidation.
