Sleep Diary Template: What to Track Before Your Insomnia Evaluation
Sleep Diary Template: What to Track Before Your Insomnia Evaluation
A sleep diary is one of the most useful tools in an insomnia evaluation. Two weeks of consistent self-recorded data gives a sleep specialist a clearer picture than a single-visit interview can. The Consensus Sleep Diary, published by an AASM-convened task force, is the field standard [Source: Carney CE et al., Consensus Sleep Diary, Sleep, 2012; accessed 2026-05-13]. This article gives you a printable template, explains what each field captures, and answers common questions about how to use it.

Why Two Weeks?
A single night is too noisy to interpret. Two weeks captures workday and weekend patterns, day-to-day variability, and the influence of social events, caffeine, alcohol, and medications. CBT-I protocols use the two-week diary as the input to set initial sleep restriction therapy windows, which is one of the most powerful insomnia treatments.
What to Track Each Day
- Bedtime — the time you got into bed
- Wake time — the time you got out of bed for the day
- Sleep onset latency — estimated minutes it took to fall asleep
- Number of awakenings — nighttime arousals you remember
- Wake after sleep onset — total estimated time awake between falling asleep and final wake
- Total sleep time — your best estimate of actual hours slept
- Daytime naps — time and duration
- Caffeine — cups, time of last caffeinated drink
- Alcohol — drinks, time of last drink
- Sleep medications or supplements — name, dose, time
- Sleep quality — 1 (very poor) to 5 (very good)

Do Not Interpret the Diary Yourself
It is tempting to add up the totals and reach a conclusion. Resist that. The diary is for your sleep physician to read in the context of your full history, medications, and any objective sleep testing. Patterns you would not notice on your own (such as wake time variability driving daytime sleepiness, or weekend recovery sleep masking workday deprivation) become obvious to a trained reader.
Common Pitfalls When Filling Out a Sleep Diary
- Filling it out at bedtime. Always fill it out in the morning when memory of the night is fresh.
- Watching the clock. Estimates are fine. Clock-watching worsens insomnia.
- Skipping bad nights. Bad nights are the most useful data.
- Adjusting behavior just because of the diary. A diary is a baseline; do not change habits during the recording window.
What Happens at the Visit
The sleep physician will review the diary line by line, calculate sleep efficiency (total sleep time divided by time in bed), look at variability, identify behavioral and pharmacologic factors, and decide whether further evaluation, including a polysomnogram, is needed. The diary is also the input for the initial sleep restriction window if CBT-I is offered.
How the Diary Drives Treatment Decisions
Two weeks of consistent diary data lets the sleep clinician compute several derived metrics that are not visible day by day: total sleep time, sleep efficiency, mean time in bed, and night-to-night variability. Sleep efficiency below roughly 85 percent is the trigger for considering sleep restriction therapy. High variability in wake time, even with adequate sleep, is a marker of poor circadian alignment and may shift the focus to schedule regularization rather than sleep restriction. The diary turns a vague complaint into a quantifiable problem with measurable interventions.
The diary is also useful for monitoring change over time. After starting CBT-I or making any major sleep-related medication change, a fresh two-week diary documents whether the change is moving the needle in the expected direction.
Bring the Diary, Not the Interpretation
The most useful posture at the first insomnia visit is “here is what I noticed, you tell me what it means.” Patients who arrive with both the raw diary and a written interpretation sometimes anchor the conversation to a wrong conclusion. The clinician’s job is to weight the diary against your full history, your medications, and any objective testing. Leave the interpretation to the visit and bring questions instead.
If you have already tried sleep hygiene, melatonin, magnesium, or over-the-counter aids, write down what you tried, for how long, and what happened. That history is part of the diary even when it does not fit in the table.
Frequently Asked Questions
How long should I keep a sleep diary?
Two weeks is the standard for an insomnia evaluation. Shorter periods are too noisy for treatment planning.
Should I use an app or paper for my sleep diary?
Either works. Paper avoids screen exposure at bedtime. Apps are convenient but should not require you to check the phone at night.
Do wearables replace a sleep diary?
No. Consumer wearables can complement a diary but are not validated for diagnostic decisions. Sleep specialists use the diary as the primary self-report.
What if I cannot fill out the diary perfectly?
Bring what you have. Even partial data is informative and shows the pattern of your insomnia.
Will I get treatment at the first visit?
The first visit is for evaluation and planning. Treatment recommendations follow review of the diary, history, and any indicated testing.
