Imagine your body has a little clock inside it that tells you when to sleep and when to wake up. Some people's clocks are like night owls, meaning they stay awake late and feel tired in the morning. Others have clocks like early birds, who get up with the sun and go to bed early. This is why some people love staying up late, while others are ready for bed as soon as the lights go out.
Examples
- Tommy prefers playing video games late into the night and feels groggy in the morning, while his sister is up with the sun and ready for school.
- Sally can’t fall asleep before midnight but gets up at 6 a. m. easily, unlike her brother who sleeps until noon.
- At night clubs, you often see more teenagers than adults, because they're natural night owls.
