Record enough, and keep it simple
A sleep diary can support a conversation with a doctor. NHLBI notes that recording sleep times, naps, daytime sleepiness and habits such as caffeine use or exercise for one to two weeks can be helpful. The purpose is to describe difficulties and their circumstances more clearly.
Choose a few fields you can realistically complete. Bedtime, estimated time of falling asleep, final awakening and one sentence about the day generally provide a clearer record than a long account written only occasionally. Label uncertain details as estimates. Minute-by-minute precision is not a reason to watch the clock at night.
Look for patterns rather than a culprit
Imagine recording worse sleep after three evenings of late work. That is a question for further observation. You do not yet know whether it relates to the work, less time available for sleep, worries about a deadline or something else. The diary records things occurring together; it cannot establish the cause on its own.
As you read back, mark workdays, days off and unusual events. Notice an ordinary night alongside the worst one. Looking only for exceptions can create a story that does not represent most of the week. Every line does not need an explanation or an immediate rule for the next evening.
Prepare a clear summary
After your chosen period, write three short sentences: what recurred, when things differed and how it affected the day. For example: 'My weekday waking times are similar. Taking a long time to fall asleep happened four times. Twice, sleepiness made me postpone something I had planned.' That is specific without pretending to be a diagnosis.
Bring the original record to your appointment too. If tracking becomes another evening burden, simplify it and discuss an appropriate approach. The diary should serve you and the person helping with your difficulties. It need not become a permanent assessment of every morning.
