What is a Sleep Diary?

A sleep diary is a record of your sleeping, including all of the aspects of your sleep. This includes data about your sleep, patterns of sleep, and sleep habits in order to identify potential problems that could signal an underlying sleep disorder. Sleep diaries are generally kept over a period of at least two weeks, but the longer the better. 

Sleep diaries might be requested of you by your doctor or a sleep center in order to get more accurate data about your sleeping.

Sleep diaries are easy to keep, usually only taking 5-10 minutes per day of effort.
