“Rest: It’s Required.” Los Angeles Times. 9 Oct. 2006). Without adequate sleeping, you may experience difficulties in concentrating and learning, reduced memory ability, and slow reaction time. Sleep deprivation can actually damage your body, too. In my case, when I get out of bed without enough sleep, I tend to eat more foods than usual. Moreover, I learned from a television news that, if adolescents do not have enough sleep, they will get an abdominal obesity and lower levels of growth hormone. This is the reason why adolescents need to have sufficient quantity and high quality of sleep. Sleep is important also for your heart because adequate sleep decreases the possibility of hypertension. Brink also said in a study published in the Aug. 2, 2006 issue of the journal that according to Sleep researcher Dr. Daniel J.

Angier says that in REM, your sensory and motor system go on actively, which makes you think that your dream is a reality(Angier, Natalie. “In The Dreamscape of Nightmares, Clues to Why We Dream at All.” New York Times. 23 Oct. 2007). However, Angier goes on saying, a small part of your brainstem makes most of your body stationary to avert you from physically carrying on your dream. Therefore most cases of sleepingwalking appear in non-REM sleep, when your body is not deactivated (Angier, Natalie. “In The Dreamscape of Nightmares, Clues to Why We Dream at All.” New York Times. 23 Oct. 2007).
