Scientists have found that in late puberty the body secretes the sleep-related hormone melatonin at a different time of day than during other stages of life. This means that teens may not be able to fall asleep until very late. They may not get adequate sleep if the school day starts early. Some schools have decided to start school an hour later. Do you think this is a good idea? Here are two points of view. Viewpoint 1: Alexa J., age 17 For the past couple of years, I haven’t been able to fall asleep until late. Then I’m really drowsy in the morning—I have a hard time paying attention in class. Getting an extra hour of sleep would make a real difference. In addition, we wouldn’t have to wait in the dark for the school bus. It’s time high schools synchronized their clocks with our body clocks! Viewpoint 2: Ray S., age 16 I don’t think starting later in the day is going to change anything. Some people will just stay up later. Also, I have a job in the afternoons. If the school day starts later, we get out later, and I lose an hour of work time. Maybe people who have trouble falling asleep should practice a routine to help wind down. My routine seems to work. By the time ten o’clock rolls around, I’m ready to hit the sack. 1. Do you think the benefits of starting school later in the day would make a difference in academic achievement? Do you agree that establishing a routine for falling asleep earlier is the way for teens to get adequate rest? 2. Research the issue of sleep cycles in adolescents. Write a short paper explaining your own views. A C T I V I T I E S Establish emotional and psychological independence. You may move back and forth between the desire for indepen- dence and the security of knowing your family supports you. Teens who have an ongoing, open communication with their parents learn the advantages of seeking advice and feedback regarding the use of decison-making and problem-solving skills. When parents or guardians discuss and explain situations, rules, or reasons in the decision-making process, teens can learn from their modeling of problem-solving skills. You will discover ways that your family’s support and guidance can help you become more emotionally and socially independent. 518 Chapter 20 Adolescence and the Life Cycle HS_HEALTH_U06_C20_L1 12/8/03 12:53 PM Page 518

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
