What are clock proteins?

Clock proteins are like little timekeepers inside your body that help you know when to wake up, eat, and go to sleep.

Imagine you have a tiny clock inside every cell of your body, it's not a watch you wear, but something even smaller, made of special proteins. These proteins work together like a team of friends who pass around a message: “It’s time for bed!” or “Time to get up!”

These clock proteins change throughout the day, just like how your mood might change from morning to night. Some of them build up during the day and then disappear at night, kind of like when you eat cookies all day and then feel full and sleepy.

When the right number of these proteins are around, it sends a signal that says, “Time for sleep!” or “Wake up now!” That’s how your body knows when to rest and when to be active, just like how you know it's time for lunch because the bell rings.
