Your body has a 'third eye' because it wants to know when it's time to sleep or wake up. It lives in your brain, behind your eyes, and it uses light like a clock to help you keep track of the day. When it sees daylight, it tells your brain it’s morning, and when it gets dark, it says it’s bedtime.
Examples
- A child stays up too late playing video games because their 'third eye' doesn't get enough dark time to tell them it’s bedtime.
- Your mom tells you it's time to go to bed, but your brain says it's still morning, your third eye is confused by the bright screen light.
- When a person travels across time zones, their third eye gets out of sync with the new day-night cycle, making it hard to sleep.
