15. Keep a Sleep Diary
When you write down your sleep experiences, including your sleep and wake times, nightmares, meal and snack times, emotional status and other related details, you’ll learn how your lifestyle and habits are affecting your sleep schedule and quality. Keep a diary for a minimum of two weeks to get a good overall view of your sleep. Additional things to note in your sleep diary include how long it takes you to fall asleep, the number of times you wake during the night, exercise, and how you feel the next morning. By comparing your habits with your sleep status, you’ll determine where you need to make changes to your regular routine and you’ll see what you did on the nights you got the best sleep.
