Do you ever feel exhausted and drowsy, like you need more sleep? If you do, you're not alone. A recent study by the National Sleep Foundation (NSF) found that 60 percent of people under the age of eighteen complained of daytime tiredness. Fifteen percent (one out of every seven) said they were so tired they fell asleep in school. You may think that not getting sufficient sleep is no big deal, but think again. According to the National Sleep Foundation, sleep deprivation can put you at high risk for unintentional injury and death, low grades and poor school performance, negative moods, and increased likelihood of stimulant use. The National Highway Traffic Safety Administration views driving drowsy as actually more dangerous, and more deadly, than driving drunk! What is sleep? Why do we need it? What causes sleep deprivation and how can it be avoided? What are its tragic results? This book answers these and other questions by using a readable blend of real-life accounts, easy-to-understand statistics, scientific data, and practical suggestions.
