NHLBI describes sleep diaries as a way to give a health professional a clearer picture of sleep difficulties. A short note can also help you explain what is happening. Record your experience; the diary itself does not diagnose or treat insomnia.

Try it

  1. After waking, note approximate sleep and wake times and anything you remember about being awake.
  2. Add a brief note about daytime sleepiness and relevant changes in routine.
  3. If sleep difficulties affect daily life, bring the notes to a qualified health professional.

What to notice

Look for questions to discuss rather than drawing a diagnosis from a few nights. Keep the record brief if tracking becomes stressful.
