Shift Work and Lark / Night Owl Tendencies

This content was created by the National Sleep Foundation

Even though most adults need 7-9 hours of sleep in a 24-hour day, exactly when our bodies naturally tend to fall asleep and wake up each day can vary. Scientists believe that people have inherent differences in when they sleep and wake best. This natural pattern is a chronotype. Whether you’re a night owl (an evening person), or a lark (morning person) is partly determined by your genetics.
