How does caffeine keep us awake? - Hanan Qasim?

Caffeine is like a tiny helper that tells your brain it’s time to stay awake.

When you drink coffee or tea, caffeine goes into your body and up to your brain. It acts like a message that says, “Hey, don’t go to sleep yet!” This message stops some of the sleepy messages from reaching your brain, so you feel more alert and ready to play, learn, or run around.

How Caffeine Works

Imagine your brain is like a room full of people talking. Some are saying, “We’re tired, let’s take a nap,” and others are shouting, “Let’s keep playing!” Caffeine is like a loudspeaker that helps the "keep playing" group be heard more clearly.

Caffeine also helps your body make more energy by telling it to use stored fuel. It’s like giving your brain an extra boost so you can stay awake longer, just like getting an extra battery in your toy robot!

So, next time you drink coffee and feel super alert, remember: caffeine is your brain's little helper, keeping the “stay awake” team strong!
