Chronotypes define our natural sleep-wake patterns, impacting productivity and well-being. There are four primary types: Larks (morning people), Owls (night people), Hummingbirds (flexible), and Bears (aligned with the sun's cycle). Understanding and aligning activities with our chronotypes enhance performance, sleep quality, relationships, and daily life. Tailoring routines and work schedules to individual chronotypes can lead to greater success and improved health.
