If you’re struggling to fall asleep or stay asleep, keeping a sleep diary can help you figure out why.
The U.S. Centers for Disease Control and Prevention suggests what to include:
- The time at which you go to bed each night.
- The time you wake up each morning, and when you get out of bed.
- If and when you nap.
- If and when you exercise.
- Consumption of any alcohol or caffeine.
