Concept
Sleep diary
Summary
A sleep diary is a record of an individual's sleeping and waking times with related information, usually over a period of several weeks. It is self-reported or can be recorded by a caregiver.
The sleep diary, or sleep log, is a tool used by doctors and patients. It is a useful resource in the diagnosis and treatment of especially circadian rhythm sleep disorders, and in monitoring whether treatment of those and other sleep disorders is successful.
Sleep diaries may be used in conjunction with actigraphy.
In addition to being a useful tool for medical professionals in the diagnosis of sleep problems, a sleep diary can help make individuals more aware of the parameters affecting their sleep. This data alone can help people self-diagnose what helps them get a good sleep.
The information contained in a sleep diary includes some or all of the following points:
The time the person had wanted or intended to wake up
The time the person woke up
Whether the person woke up spontaneously, by an alarm clock, or because of another (specified) disturbance
The time the person got out of bed
A few words about how the person felt during the day (mood, drowsiness, etc.), often on a scale from 1 to 5 and the major cause
The start and end times of any daytime naps and exercises
The name, dosage and time of any drugs used including medication, sleep aids, caffeine and alcohol
The time and type/ heaviness of evening meal
Activities the last hour before bedtime, such as meditation, watching TV, playing PC-games
Stress level before bedtime, often on a scale from 1 to 5 and the major cause
The time the person tried to fall asleep
The time the person thinks sleep onset occurred
Activity during aforementioned two moments (remaining eyes closed, meditating, etc.)
The presumed cause, number, time, and length of any nighttime awakenings and activities during these moments
Quality of sleep
Level of comfort of any recalled good or bad dreams
Sleep logs are often hand-drawn on graph paper, as a rule one week per page.
