Wakefulness

Wakefulness basically means staying awake and not feeling sleepy. When we are awake, our brain is sending signals to our body to keep us alert and active so we can do different things.

Think of your brain as a watchman who keeps a close eye on you while you're awake. The watchman keeps you alert and awake by sending signals to different parts of your body so they stay active. These signals help you to stay attentive, focused, and ready to learn new things.

But, just like how your body needs rest after playing all day, your brain also needs rest after staying awake for a long time. When you feel tired, it's a signal from your brain that it needs a break. So, when you feel sleepy, lying down and closing your eyes helps your brain to relax and recharge.

Overall, wakefulness is when your brain is sending lots of signals to your body to keep you active and alert, which helps you to learn and do lots of fun things!
