The Magic of Light
Why You Feel Tired at Night
At night, when it gets dark, your body starts producing another chemical called melatonin, which makes you sleepy. So, the cycle of light and darkness helps control how we feel during the day.
Examples
- When you wake up on a sunny day, you feel more ready to run around the playground than after a rainy night.
- Even if it's still dark outside, your alarm clock helps you start moving and feeling alert.
