NCERT Chapter Summary: The Wonder Called Sleep

When we sleep our body and brain recovers from weariness caused by various activities during the day. We become attentive and active after a good sleep. We become ready for the usual activities of the day.

It is not always possible to recall what happened when we were asleep. We may remember a dream but nothing else. When we enjoy more and more sounds sleep, our muscles relax and heartbeat becomes slower.

Our temperature and blood pressure both go down. The ever-active brain also slows down so that we could not think and put pressure on our mind. When we wake up, our temperature and blood pressure rise to normal. 

Dream is an Activity of the Mind

The dream is an activity of the mind when we are asleep. Some dreams appear to be true while others are not. Many of the things that happen in dreams won’t happen when we are awake. Dreams are important as they can help us to sleep in spite of noise or other disturbances.

Dreams may Reveal Something about One’s Problems

Some doctors say that dreams can reveal a great deal about one’s problems and can provide a key to the solution of those problems. But, dreams can never tell about the future. Sleep is the most common experience but we rarely think about the wonder and power of sleep. Sleep makes us lose ourselves in a dark forest. Nobody can avoid sleep for long, one has to accept it sooner or later.
