Why we sleep

Think about a day when you played a lot. By the evening your body is tired. Your book, Our Wondrous World (Chapter 6), says that our body needs enough sleep every day.

A good sleep takes away our tiredness and makes us feel fresh the next morning. When we do not get enough sleep, it is hard to focus on our work or our play. We feel tired, sleepy and irritable (easily upset or grumpy).

So sleep is just as important as eating healthy food and exercising. After a busy day of exercise and play, the body needs rest, and a good night's sleep gives it that rest.
