For questions 8 10, complete the sentences with the in formation given in the passage. Sound Effects Snorers(打鼾的人 ) have always been ma

5、de jokes. In cartoons, their nasal(鼻子的 )roar lifts the roof off houses. In situation comedies, theres the wife who rolls her eyes at her snoring bedmate. But in reality, its not all that funny. In fact, snoring can be a nightmare for snorers and their troubled partners, who may wake up several times

6、 a night to poke, and maybe hoist loved ones onto their sides for a little relief. Risks of Snoring Problems But the nightly racket is more than a potential relationship strain. According to the latest research, an increasingly older and heavier population may make this condition an even greater a h

7、ealth risk than we previously thought. For Maggie Moss-Tucker, successful treatment for a longtime snoring problem came almost by accident. One fall morning in 2005, she saw a sign at her local gym seeking snorers as volunteers for a study at Bostons Brigham you never talked about it with your docto

8、r, “says Dr. David Rapoport, medical director of the Sleep Disorders Center at New York University Medical Center. “But when it becomes very prominent or such that it wakes you up or interferes with breathing, it can be a problem.“ Sleep apnea, in which the airway becomes blocked or, less often, the

9、 brain fails to properly control breathing during sleeping, can be viewed as one extreme of the snoring spectrum. Soft snoring, which is not generally considered a health hazard, would be at the other end. As the sound and persistence of a patients snoring grows, so do the health concerns. A study p

10、ublished in the March 1 issue of the journal Sleep found that loud snorers had a 40 percent greater risk than non-snorers of suffering from high blood pressure, 34 percent greater odds of having a heart attack and a 67 percent greater chance of having a stroke. Thats a problem given the number of no

11、isy sleepers out there. In a recent poll by the National Sleep Foundation, about one third of US working adults reported snoring at least a few nights in the previous month. Snoring generally worsens with age so the rate is even higher among the elderly. And, contrary to common perceptions, its near

12、ly as common in women as men. Menopause(更年期 ) appears to be a factor, as is weight. Being overweight can cause thickness in the airway tube, holding back the flow of oxygen. Treatment of Snoring Problems Yet many who regularly snore dont realize that it could be bad for their health. The research li

13、nking hypertension, cardiac problems and loud snoring is relatively new. And though awareness of sleep apnea is growing, specialists say the condition is still vastly undertreated. Primary-care physicians dont routinely ask patients about the quality of their sleep though that is beginning to change

14、 and few patients think to tell their doctors that theyre snoring, unless it becomes hazardous to their partner. Sleep specialists estimate that between 12 million and 18 million Americans have some form of sleep apnea but many of them, like Moss-Tucker, remain undiagnosed for years. Research from t

15、he National Sleep Foundation indicates that only half of those with sleep apnea are being treated. Since it is a progressive condition, says Michael Twery, director of the National Institutes of Healths National Center on Sleep Disorders Research, “The person whos affected is usually not aware of ho

16、w severe the condition is.“ Moss-Tucker remembers being drowsy during the day sometimes, but she blamed it on her busy life. When researchers at the sleep lab asked if she had ever fallen asleep while driving, she laughed initially. But then she recalled long drives during which shed had to pull ove

17、r every 45 minutes to take a cat nap(打盹 ) to avoid dozing off at the wheel. Shed also become accustomed to taking daily 25-minute naps each afternoon. But once she was diagnosed and began using a Continuous Positive Airway Pressure (or CPAP) machine, the most common treatment for sleep apnea, she sa

18、ys, “My life changed.“ Moss-Tucker no longer needed naps and her energy levels, mental clarity and general moods improved so much so that she cannot imagine one night without the CPAP, a machine with a mask that attaches to the nose, mouth or both, helping to force oxygen into the airway while the p

19、atient sleeps. If its used properly, it is nearly 100 percent effective. But CPAPs (or BiPaps, which deliver alternating levels of oxygen), which cost about $ 500 or more with the mask, can be not easy to use and the noise may be as disruptive to sleeping partners as snoring. Despite its efficiency,

20、 estimates of overall long-term usage rates remain between 50 to 70 percent. For snorers who dont appear to have sleep apnea, there are other measures to avoid bad nights. They include: avoiding big meals and alcohol before bed; sleeping on ones side instead of the back; treating conditions tike all

21、ergies and colds that can cause or worsen snoring, and maintaining a healthy weight. There are also devices, which push the lower jaw forward to help keep the airway open. “They arc effective in a fair number of snoring cases,“ says NYUs Rapoport, but he cautions that they need to be custom fitted b

Surgery on Snoring Problems Surgery to widen the airways or improve nasal airflow is also an option, though it also may not be covered by insurance and success rates vary. UPPP, in which a surgeon removes tissue at the back of the throat, c

23、an require a hospital stay and a long recovery; its typically used for patients with moderate obstructive sleep apnea. But other procedures can be performed under local anesthesia in a surgeons office, including laserassisted LAUP, a modification of UPPP in which the surgeon uses a laser to cut the

24、uvula. Patients who get LAUP can generally resume their normal routine almost immediately afterward, but they may require up to five treatments. Somnoplasty is another short office-based procedure: it uses low-power radiofrequency energy that reduces tile volume of the soft palate tissue (located at

25、 tile back of tile roof of the mouth) but may require more than one session. Nasal surgery may also be recommended for those with obstructions in the nose. Another treatment is file Pillar procedure, in which three tiny inserts are injected into the soft palate to offer support. Since its a newer pr

26、ocedure only approved by the FDA in August 2004, theres less long-term data. “Studies are showing it does work but to what extent is not really known yet.“ says Rapoport. With several options but no magic bullet, experts say its important to have a full medical examination to determine the best cour
