Over 1. 1 billion teenagers and young adults worldwide could be at risk of hearing loss as a result of【 C2】 _to unsafe levels of recreational noise

24、, according to a recent World Health Organization report. To make matters worse, this kind of hearing loss doesnt show up on【 C3】 _tests. Researchers are calling it a hidden epidemic. “ We think this problem is【 C4】 _prevalent, but its difficult to measure because the tools we have available today a

30、for everything from obesity to mental health as experts say carving out time for sleep is just as important as diet and exercise. BAfter being diagnosed with brain and lung cancer in 2011, Lynn Mitchell, 68, was averaging about an hour of solid sleep a night. Stressed about her treatments, she was p

31、aying for it in hours of lost sleep. The brain cancer was already affecting her mobilityMitchell was often dizzy and would lose her balancebut the lack of sleep was making things worse. Even walking became increasingly difficult. Exhausted in the mornings, she was practically incoherent. When her do

32、ctors recommended she see a sleep therapist, Mitchell was relieved at how benign it sounded in comparison to the chemotherapy(化疗 )she had undergone, which had side effects like nausea and fatigue. CFor about nine weeks, Mitchell worked with the sleep therapist to adjust her sleep habits. She got und

33、er the covers only when she was extremely tired. She quit watching TV in bed. She stopped drinking caffeinated coffee in the evening. She also learned breathing exercises to relax and help her drift off. It was all quite simple and common sense, and, most importantly, noninvasive and didnt require p

34、opping any pills. D“ Its common knowledge that sleep is needed for day-to-day function,“ says Dr. David Rapoport, director of the Sleep Medicine Program at NYU School of Medicine. “ What isnt common knowledge is that it really mattersits not just cosmetic. “ Rapoport has long seen people seek sleep

35、therapy because theyre chronically tired or suffering from insomnia(失眠 ), but an increasing number of patients are being referred to his center for common diseases, disorders, and mental health. EResearchers have known for some time that sleep is critical for weight maintenance and hormone balance.

36、And too little sleep is linked to everything from diabetes to heart disease to depression. Recently, the research on sleep has been overwhelming, with mounting evidence that it plays a role in nearly every aspect of health. Beyond chronic illnesses, a childs behavioral problems at school could be ro

37、oted in mild sleep apnea(睡眠呼吸中止症 ). And studies have shown children with ADHD(注意力缺损多动障碍 )are more likely to get insufficient sleep. A recent study published in the journal SLEEP found a link between older men with poor sleep quality and cognitive decline. Another study out this week shows sleep is e

38、ssential in early childhood for development, learning, and the formation and retention of memories. Dr. Allan Rechtschaffen, a pioneer of sleep research at the University of Chicago, once said, “ If sleep does not serve an absolutely vital function, then it is the biggest mistake the evolutionary pr

39、ocess ever made. “ FBut to many of us, sleep is easily sacrificed, especially since lack of it isnt seen as life threatening. Over time, sleep deprivation can have serious consequences, but we mostly sacrifice a night of sleep here and there, and always say that well “catch up“. Luckily, it is possi

40、ble to make up for sleep debt(though it can take a very long time), but most Americans are still chronically sleep deprived. GWhile diet and exercise have been a part of public health messaging for decades, doctors and health advocates are now beginning to argue that getting quality sleep may be jus

41、t as important for overall health. “ Sleep is probably easier to change than diet or exercise,“ says Dr. Michael Grandner, a sleep researcher at the University of Pennsylvania. “It may also give you more of an immediate reward if it helps you get through your day. “ And while theres more evidence li

42、nking diet and exercise as influential health factors, sleep is probably more important in terms of brain and hormonal function, Grandner says. “ Among a small group of sleep researchers, its always been said that eating, exercise, and sleep are the three pillars of health,“ says Dr. Rapoport. HIn o

43、ur increasingly professional and digital lives, where there are now more things than ever competing for the hours in our day, carving out time for sleep is not only increasingly difficult, but also more necessary. Using technology before bed stimulates us and interferes with our sleep, yet 95% of Am

44、ericans use some type of electronics like a computer, TV, or cell phone at least a few nights a week within the hour before we go to bed, according to a 2011 National Sleep Foundation survey. “Many doctors, lawyers, and executives stay up late and get up early and burn the candle at both ends,“ says

45、 Dr. Richard Lang, chair of Preventative Medicine at the Cleveland Clinic. “Making sure they pay attention to sleep in the same way they pay attention to diet and exercise is crucial. “ ITo some, sleep has become a powerful medicine to mental health. Arianna Huffington, president and editor-in-chief

46、 of the Huffington Post Media Group, advocates that sleep is the secret to success, happiness, and peak performance. After passing out a few years ago from exhaustion and cracking a cheekbone(鹳骨 )against her desk, Huffington has become something of a sleep promoter. In a 2010 TED Women conference, H

47、uffington said, “The way to a more productive, more inspired, more joyful life is getting enough sleep. “ Research linking high-quality sleep with better mental health is growing: a 2013 study found that treating depressed patients for insomnia can double their likelihood of overcoming the disorder.

48、 JWhile 70% of physicians agree that inadequate sleep is a major health problem, only 43% counsel their patients on the benefits of adequate sleep. But theres growing pressure on primary care physicians to address, and even prescribe, sleep during routine check-ups. In a recent study published in th

49、e journal The Lancet Diabetes & Endocrinology, the researchers concluded that health professionals should prescribe sleep to prevent and treat metabolic disorders like obesity and diabetes. And overlooking sleep as a major health issue can also have deadly consequences. It was recently reported that the operator of the Metro-North train that derailed in New York last year, killing four people and injuring more than 70
