Do you find bedtime annoying?  Are you tired of being told that you need your sleep?

Let's find out why going to bed is a good thing, and why humans have to sleep in the first place.

What is sleep?

When we sleep, our eyes are closed and our muscles are relaxed.  We breathe slowly and don't take notice of anything going on around us (unless it's very loud or bright, or hurts).

What are we doing when we are asleep?

You might think that nothing much is happening while we are sleeping, but you would be wrong.  Your body and brain are actually getting up to quite a lot, you just don't know it.

For example:

  • Dreams and memory.  Nobody knows exactly why we dream, but we do know that sleeping affects how well we are able to remember things.  If we don't get enough sleep, we find it hard to hang on to all those things we've learned during the day.

You don't want to have to learn the same things over and over again in school, do you?

Not only that, but if you don't get enough sleep then you may start to find it hard to speak and think properly.  This is most important when we are young and our brains are still growing.


  • Staying fit and well.  Sleep helps us recover from the work we did when we were awake.  It is especially important for helping our bodies protect us against germs and viruses. Also, people who don't sleep enough tend to eat more, and eating too much of the wrong kinds of food really isn't good for us.

Not getting enough sleep can make us tired (obviously) but also grumpy, dopey, sleepy, sneezy - in fact, we could turn into most of the seven dwarfs if we are not careful!

So, next time you feel like complaining about having to go to bed, try to remember the reasons why we need to sleep and the idea may not seems so bad after all.
