Imagine your body has a special clock that tells it when to go to sleep and when to wake up. Some people have clocks that say, 'It’s time for bed!' early in the evening, while others think, 'I’m still awake! I want to stay up longer.' This is why some people are early birds and others are night owls.
Examples
- One child sleeps right after dinner, while another stays up watching cartoons until midnight.
- A teacher feels most alert in the morning, but a teenager can't go to bed before 12:00 a. m.
- Some people wake up naturally at 6:30 a. m., while others hit snooze three times.
