Imagine your body has a tiny clock inside it that tells you when to be awake and when to sleep. Some people have clocks that wake them up early, like a morning bird, while others are more like owls who prefer the night. This is why some people are ‘morning’ people and others are ‘night’ people.
Examples
- A student who wakes up early for school feels tired if they stay up late on the weekend.
- An office worker prefers working nights and feels most energetic after midnight.
- A night owl is still wide awake at midnight while their friend is already asleep.
