Excessive Sleepiness: Overview


Excessive sleepiness becomes a problem when the person cannot stay awake and alert long enough to complete daily tasks.

Excessive sleepiness is different from fatigue or physical tiredness. Excessive sleepiness may increase the risk of car, work, or home accidents. It may also cause poor school or work performance.

Memory problems and changes in behavior also can occur.
