Hypersomnia , as daytime sleepiness is also called, affects one’s cognitive function and alertness, thus heightening one’s risk of accidents or mistakes. While some causes can be worked with and managed, some triggers may be beyond one’s control.

Here are a few common causes of excessive daytime sleepiness:

The most common cause is inadequate sleep during the night, leading people to want to take naps during the day.
