Sleep Diary

Log consistently

Try to fill out your sleep diary each morning while your sleep is still fresh in your mind.

Estimate if necessary

If you're not sure exactly when you fell asleep, make your best guess rather than skipping the entry.

Note influencing factors

Record any factors that might have affected your sleep like caffeine, stress, or exercise.

Don't watch the clock

Checking the time throughout the night can increase sleep anxiety. Try to avoid this.
