1. Describe what happens during NREM and REM sleep.

A: In the beginning of a sleep cycle, we enter NREM sleep. The body recovers from the stress of the day's activities during this part of the sleep. Then, about 1.5 hours into sleep, we enter REM sleep, or dream sleep. Our eyes move rapidly during this phase of sleep. Throughout the entire sleep cycle, periods of NREM sleep alternate with periods of REM sleep.

2. Which common causes of insomnia can you control? What changes would make the most improvement to your sleep?

3. Do you think insomnia can affect teens? Explain.

A: Yes, I do. I believe this because stress, as well as the other causes, is a common cause of insomnia in which fills a teenager's life?

4. Give reasons why teens need more sleep than adults do.

A: Teenagers need more sleep than adults do because, when puberty takes place, the timing of a teenager's circadian rhythm, the body's internal system for regulating sleeping and waking patterns, is delayed. When the rhythm is delayed at puberty, the body naturally wants to rest later at night and awaken later in the morning. So, teenagers usually have more difficulty falling asleep until late at night and have a more difficulty waking early in the morning?

b. Overtraining and RICE corresponds with each other, since overtraining can cause chronic injury. RICE is applied to these chronic injuries and enables them to heal.
c. Sleep apnea and sleep deprivation are correspond with each other. Sleep apnea is a sleeping disorder characterized by interruptions of normal breathing patterns during sleep, which results in sleep deprivation, a lack of sleep.
