sleep diary

A sleep diary is a record of your sleep patterns over a long period of time (usually at least 2 weeks). It includes the time you go to sleep and wake up. A sleep diary can help doctors diagnose sleep disorders.

A sleep-wake diary (or journal) tracks more data than a sleep diary and can help you see patterns, such as:

  • How your energy and alertness change during the day and
  • What may be making your symptoms better or worse
