How to Keep a Sleep Diary Before a Sleep Appointment

The US National Heart, Lung, and Blood Institute suggests that keeping a diary for one to two weeks before seeing a doctor may be helpful. It recommends noting sleep and waking times, naps, daytime sleepiness and the timing of caffeine, alcohol and exercise.

If your clinic has sent a form or given a different timeframe, follow its instructions. Bring the entries you have if the appointment arrives sooner. Do not postpone seeking help to complete a perfect two-week record.

Choose a consistent point after waking to fill in the previous sleep period. If you work nights, that may be after an afternoon sleep rather than in the morning. Label dates clearly when a sleep period crosses midnight.

The 2012 Consensus Sleep Diary paper describes an expert-developed, patient-informed approach to recording sleep. It separates getting into bed, trying to sleep, time awake and getting out of bed. The paper proposed a standardized diary for research; it did not establish that a consumer app or this simplified template treats insomnia.

For an appointment, those distinctions are more useful than a single “good night” or “bad night” label. You can also record sleep quality in your own words and how sleepiness affects your day. Keep naps separate from your main sleep period.

Copy this into a notebook or private document. It is an original editorial worksheet, not the official Consensus Sleep Diary, a validated assessment or a replacement for your clinic's form. If you prefer a ready-made printable sheet, the NHLBI provides a free sleep diary.

Sleep period: from [date] to [date]
Got into bed at:
Started trying to sleep at:
Estimated time until sleep: [minutes]
Awakenings before final waking: [number, if remembered]
Estimated total time awake during those awakenings: [minutes]
Final waking time:
Got out of bed at:
Sleep quality in my own words:

Separate daytime notes:
Naps: [approximate time and length]
Sleepiness and effect on daily activities:
Caffeine or alcohol: [approximate amount and time, if relevant]
Medicines or sleep products: [name and time, if relevant]
Exercise, work shift or other context worth mentioning:

Make rough estimates after waking. This template does not require watching the clock overnight. “Not sure” is an acceptable entry. If you miss a day, leave it blank or clearly label any later recollection.

Keep the record descriptive. Note what you already took; do not start, stop or change medicines or sleep products to improve a diary result. Discuss those decisions with your prescriber or pharmacist.

These entries are invented to demonstrate the format. They are not a person's health record or evidence that a particular routine helps sleep.

Sleep period: Friday evening to Saturday morning
Got into bed: 10:30 pm
Started trying to sleep: 11:00 pm
Estimated time until sleep: 20 minutes
Awakenings before final waking: 2
Estimated total time awake during those awakenings: 20 minutes
Final waking: 6:40 am
Got out of bed: 7:00 am
Sleep quality: Interrupted; felt somewhat rested on waking
Daytime note: Felt sleepy during a quiet afternoon meeting

In this example, time in bed is 8 hours 30 minutes, from 10:30 pm to 7:00 am. Estimated sleep is 7 hours: the 7 hours 40 minutes between trying to sleep and final waking, minus 20 minutes before falling asleep and 20 minutes awake during the night.

The half-hour before trying to sleep and the 20 minutes after final waking count as time in bed, not sleep. All the sleep estimates remain subjective. You do not need to calculate a percentage, meet a target or shorten your time in bed based on this example.

Use the same fields for each separate sleep period and label whether it followed a night shift, a day shift or a day off. Avoid forcing a daytime sleep into an overnight date column. Your clinician can help decide which periods to compare.

Our guide to shift work, sleep and mental wellbeing discusses that context. If you also want a separate record of feelings, the mood diary template keeps those observations distinct from sleep estimates.

Bring the diary, a list of medicines and supplements, and a short description of the concern: when it began, how often it happens and how it affects your day. Mention snoring, gasping or breathing pauses that someone else has noticed. Include your questions rather than trying to arrive with a diagnosis.

A pattern is a starting point for discussion. Recording a poor night after an evening coffee does not prove that the coffee caused it. A few reassuring entries do not rule out a sleep disorder either.

You can keep the log on paper. If you already use PsychPod, its check-ins and journal can hold separate reflections on sleep, mood and energy. Follow the clinic's requested sleep diary format; a wellbeing score does not replace it. PsychPod's combined score is not clinically validated and does not diagnose, treat, predict crises or monitor your safety. Its methodology explains those limits.

NHS insomnia guidance recommends seeking medical advice when changes to sleep habits have not helped, difficulties have lasted for months, or sleep problems make daily life hard to cope with. You can ask for help sooner when symptoms are concerning.

NHS sleep apnoea guidance advises assessment for symptoms such as breathing pauses, gasping or choking during sleep, or persistent daytime tiredness. A diary cannot confirm or exclude sleep apnoea; testing may be needed. Our sleep apnoea guide explains why time in bed alone is not enough to assess it.

Do not drive when you feel sleepy. If logging becomes a source of repeated checking or distress, simplify it and discuss the difficulty with your clinician, especially if it is part of an agreed monitoring plan.
