Sleep patterns are not just reflections of how much rest the body gets; they also determine our productivity, physical health, and surprisingly, even our relationships!
Sleep patterns define how your body feels naturally when it is awake or if it should be resting, and these patterns of when we feel sleepy or most awake are what we call sleep chronotypes.

What Are Sleep Chronotypes?

Sleep chronotypes are initially described by Horne and Östberg as the individual differences in the timing of peak alertness, physical activity, and other physiologic functions throughout the day.
You can think of it as your body’s internal clock that dictates when you’re most awake and productive, and when you usually feel sleepy and tired.
