Can you change your sleep schedule?

Are you an early bird or a night owl? Explore how your circadian system acts as an internal clock to keep your body functioning. An early bird rises with the sun, springing out of bed abuzz with energy. Meanwhile, a night owl groggily rises much later, not hitting their stride until late in the day. How many people are truly night owls or early birds? And are our sleep schedules predetermined at birth, or can we change them? Explore how our circadian systems act as internal clocks to keep our bodies functioning properly. Directed by Avi Ofer.
