Ellen Sims is an 18-year-old college student. She has an important exam tomorrow morning. Ellen is going to study all night. Many college students, like Ellen, do this often. They think they can study all night. And they think that in the morning, they will remember everything that they studied the night before. Ellen thinks that this is a good way to study, but many doctors disagree. They say that sleep is very important for memory and brain development. Scientists in Harvard Medical School studied sleep and memory. They studied 24 people. First, they asked the people to look at the picture and remember it. At night, they put the people in two groups of 12. Group One went to sleep. Group Two did not. A few days later, the scientist showed some picture to both groups. They asked the people to find the picture they saw before. The people in Group One did well. But the people in Group Two did not well. It wasn’t easy for them to remember the picture. What happened? Scientists say that sleep helps our memory. After we learn something new, sleep helps us remember it. And when we don’t sleep, we can forget new things. Scientists say that many teenagers, like Ellen, sleep too little. They go to school and they work, too. They also spend time with their friends. They are always busy and they think that sleep doesn’t matter. But scientists say the brains of teenagers are still developing, and sleep is a very important part of the development. When teens sleep less than six hours, they can’t think clearly. That is not very helpful for a student who is taking an exam.
