During the day we work and play; at night we sleep. Our bodies rest while we sleep. In the morning we are ready to work and play again. While we are asleep our bodies grow most. Children who are tired usually need more sleep. We can get our lessons better and we feel better too, when we have had plenty of rest. Boys and girls who are eight or nine years old need ten hours of sleep every night. Our bodies need plenty of air when we sleep.
