Here is the audio file for Attitudes Toward Sleep.
How much do you sleep? Most teenagers do not get enough sleep. Someone in his or her teens actually needs more sleep than a slightly younger child because teenagers’ brains and bodies are changing more dramatically than any time other than early childhood (infant to age 3 or 4). Current recommendations are that teenagers get at least 8.5 hours, and preferably up to 10 hours of sleep per night.
Lack of sleep can have negative effects on concentration, metabolism, mood, and ability to cope with stress. Sleep deprivation also causes errors in judgement and delays in reaction time comparable to alcohol intoxication.
