The Center for Center for Disease Control and Prevention (CDC) estimates that 60 million American adults suffer from a sleep disorder (“Insufficient sleep is a public health epidemic "). This means that about 20% of adults in the United States have trouble sleeping at night. When people don't sleep on time, they don't get enough sleep at night, which leads to sleep deprivation. Lack of sleep is a growing problem in schools and the workplace; therefore, the symptoms, causes, consequences and solutions must be known. The first and most important is to identify the symptoms of lack of sleep. Sleep deprivation is a form of psychological torture caused by lack of sleep. Although lack of sleep may be apparent to some, others may have difficulty spotting the signs of sleep deprivation. Some symptoms of sleep deprivation are so common that it can be difficult to identify them. Examples of these symptoms include snoring, excessive yawning, and feeling unrefreshed when you wake up in the morning. The Centers for Sleep Control and Prevention says that, increasing over the past 20 years, about 30 percent of adults sleep six hours or less each night (Harris). Adults need at least 8 full hours of uninterrupted sleep to function properly during the day, as the CDC explains. Sleeping less than this recommended amount can leave many adults feeling sluggish throughout the day. Harris cites the large number of people who don't get enough sleep in hopes of raising awareness of this growing problem. Brad Wolgast, a psychologist at the University of Delaware, says: "When you have depression, even when you feel anxiety, when you scratch the surface, 80 to 90 percent of the time you also discover a sleep problem . middle of paper ...naps are a great way to feel rested, but they should be limited to about 15 minutes (Nelson 75). The problem with naps is that the naper doesn't set limits. Most people tend to nap for an hour, which causes sleep inertia and makes them feel even more tired. Sleep inertia can occur in just a half-hour nap. Overall, lack of sleep is a serious and growing problem. Many people of all ages suffer from it every day due to stress, anxiety, depression and technology. High sleep debt may be apparent among students and workers, and it can also be dangerous for the people around them. Although a nap may be a short-term solution to a long-term problem, anyone deprived of sleep should seek help from a doctor. Sleep deprivation is a serious problem whose symptoms, causes, consequences and solutions must be known..
