Imagine your body has a built-in clock that tells you when to be awake and when to go to sleep. Some people have clocks that make them wake up early, like the sun rising, while others are more like night owls who prefer to stay up late and sleep in. These different clocks explain why we all sleep differently.
Examples
- A teacher who wakes up at 6 a. m. and is ready to start school by 7 a. m.
- A teenager who stays up until midnight watching videos and sleeps in until 9 a. m.
- A night shift worker who goes to sleep after midnight and feels alert during the day.
