A sleep diary is a daily record of important sleep-related information. Although not all sleep diaries are identical, they commonly include details about:
Sleep diaries are also called sleep journals or sleep logs. These terms are typically used interchangeably, although some consider a sleep diary to be more detailed than a sleep log. Regardless of the name, all of these are patient-recorded methods of tracking information about sleep.
By keeping a record of sleep, the diary makes it possible to calculate total sleep time. A sleep record also helps people identify sleep disruptions and other factors that can influence sleep quality.
Identifying details about habits that affect sleep can show patterns that help explain sleeping problems. For healthcare providers, the concrete entries in a sleep diary are often more reliable and usable than a general recollection about sleep habits.
Another way that a sleep diary is used is in preparation for certain specialized sleep studies. A sleep diary can enhance the validity of sleep tests by showing that a person’s sleep is stable in the lead-up to the study.
Staying current and updating your diary as you go helps avoid any gaps in your memory. For that reason, you want to keep your sleep diary and a pen in an easily accessible place where you’ll be reminded to fill it out every day.
If you’re filling out a sleep diary on doctor’s orders, make sure to use the form they provide and follow any accompanying instructions.
