Imagine your body has a sleepy switch, and some people turn it on faster than others. When you're tired, this switch helps you go to sleep quickly, like flipping a light switch. But if the switch is slow or broken, falling asleep becomes harder. This switch lives inside your brain and uses messages from your body.
Examples
- A child falls asleep quickly after a bedtime story, while their older sibling lies awake for hours.
- A person can go to bed and fall asleep in minutes, but their friend needs an hour of reading before they drift off.
- Some people fall asleep on the bus during a long ride, while others remain wide awake.
