The average sleeping time for an adult is eight hours. There are several causes as to why a person sleeps too much -- a condition medically termed as hypersomnia or oversleeping. However, some common causes are stress, lack of self-discipline, and poor sleep in a span of a couple of days.
Hypersomnia means excessive sleepiness. There are many different causes, the most common in our society being inadequate sleep. This may be due to shiftwork, family demands (such as a new baby), study or social life. Other causes include sleep disorders, medication, and medical and psychiatric illnesses.
