THE CDC:
The Centers for Disease Control and Prevention (CDC) is always busy monitoring health issues and sending out regular warnings to make sure people know of any impending threats. One of the most recent warnings, however, caught Americans by surprise. The CDC announced that one of today's most under-recognized public health problems is sleep loss. It is estimated that between 50 and 70 million Americans suffer from this problem. Adequate sleep is essential to good mental and physical health. If you do not get enough sleep on a regular basis, you run an increased risk of obesity, diabetes, high blood pressure, stroke, cardiovascular disease, depression, cigarette smoking, and excessive drinking. Those are not minor health issues!
To find out how many Americans are not getting enough sleep, the CDC surveyed almost 20,000 adults in four states. Ten percent of the people studied reported not getting enough sleep every single day of the previous month, and 38 percent reported not getting enough in seven or more days in the previous month. How much sleep is enough sleep? According to the National Sleep Foundation, adults need 7 to 9 hours each night, whereas children under 12 need 9 to 11 hours and teenagers need between 8½ and 9½ hours.
Unfortunately, instead of sleeping, many people stay up late at night to surf the Internet or watch television. Along with the health risks that chronic sleep loss can bring, experts also believe it is responsible for thousands of people who die on the road each year from accidents caused by sleepy drivers. There is no doubt that spending less time with eyes closed can make your days longer, your health worse, and your driving riskier.

PHOTOTHERAPY:
Phototherapy, commonly referred to as light therapy, has been an established form of medicine for more than a century. In recent years it has become closely associated with seasonal affective disorder, of which it is an effective and well-known treatment, but it is also used to treat a broad range of medical issues including acne, psoriasis, and eczema.
The most common form of light therapy involves a patient sitting in front of a medically designed light box for a prescribed amount of time every morning. The light is positioned at an exact distance from the patient's eyes so that it strikes both the skin and the retina. The light box mimics the effects of natural sunlight, but the UV rays are filtered to ensure there is no damage to the patient's skin or eyes. Phototherapy is thought to be a safe method of reducing the amount of bacteria on the skin, reducing inflammatory responses, and affecting the chemicals in the brain associated with mood.
One of the most recent technologies to be associated with phototherapy is the phototherapy blanket. In the late 1960s it was discovered that phototherapy can be used to treat jaundice in newborn babies. Neonatal jaundice, a yellowing of the skin in newborn infants due to excess bilirubin levels in the blood, is usually harmless but can cause brain damage if left untreated. Newborns are given a phototherapy blanket, a small pad with flexible LED light panels sewn into the fabric, to sleep with until their livers are able to process the excess bilirubin.
The many benefits of phototherapy make it a valuable resource for addressing a variety of ailments. Emerging innovations in LED and photo technologies ensure that many more practical applications will be developed for this particular form of treatment in the years to come.
Question 2 of 5
Which statement would not be inferred by the reader?
Correct Answer: D
Rationale: The correct answer is D. While the passage extensively discusses the benefits and applications of phototherapy, it does not mention that ultraviolet rays can cause damage to eyes and skin. This statement goes beyond the information provided in the passage and cannot be inferred.
A. The passage mentions that phototherapy has been around for more than a century, supporting the statement that some forms of phototherapy have been around for decades.
B. The passage discusses how new applications of phototherapy, like the phototherapy blanket, are being developed, making this statement valid as it aligns with the information provided.
C. Phototherapy being most often used to treat skin problems is supported by the passage, which mentions its applications in treating acne, psoriasis, and eczema.
Therefore, this statement can be inferred from the passage.
Question 3 of 5
Which of the following statements is a fact?
Correct Answer: B
Rationale: The correct answer is B: 'Untreated jaundice may cause brain damage.' This statement is a fact supported by the passage. Neonatal jaundice, if left untreated, can lead to brain damage due to excess bilirubin levels in the blood.
Choice A is not a fact but a general guideline for nurses.
Choice C is an opinion as it describes phototherapy blankets as valuable without citing a specific fact.
Choice D is not a fact but a recommendation, advising to avoid neonatal units lacking phototherapy.

EXERCISE:
It sounds contradictory, but here is some new advice for people who are feeling unusually tired: get out and get some exercise. Studies have shown that regular, low-impact workouts such as short strolls or brief bike rides can help increase overall energy levels by 20 percent and decrease fatigue levels by 65 percent. In other words, if you are feeling tired, the best way to feel more energetic is to get some exercise.
This advice is based on a study done by the University of Georgia's Exercise Pathology Lab. Three dozen people who did not get any kind of regular exercise yet consistently felt exhausted were divided into three groups. One group did not exercise at all. A second group worked out intensively on an exercise bike three times a week. The third group also worked out but at a slower pace. Of the two groups that exercised, both reported a 20 percent increase in energy levels. However, the group that exercised at a more leisurely pace stated that they experienced far less fatigue than the high-intensity group.
This was not the first study to point out a link between regular exercise and energy levels. The same team that conducted it also published one several years ago that stated that low-impact exercise can also help reduce fatigue in patients with serious health conditions such as heart disease and cancer. Clearly, it is time to get off the couch and onto the track.
Question 4 of 5
Which statement could be inferred from the passage?
Correct Answer: A
Rationale: The correct answer is A. The passage mentions a previous study by the same team on the connection between exercise and energy, indicating that the lab had conducted such research before.
Choice B is incorrect because the passage actually states that low-impact exercise can help reduce fatigue in patients with serious health conditions.
Choice C is incorrect as the passage indicates that an increase in energy levels does correspond to a reduction in fatigue.
Choice D is incorrect as the passage does not provide information on the exact number of participants in each group.

EATING DISORDERS:
It is hard to imagine how the eating disorders anorexia and bulimia could be any worse than they already are, but somehow people have found a way. Known unofficially as drunkorexia, this condition is a blend of self-imposed starvation or binging and purging mixed with alcohol abuse. Anorexics may use alcohol either to soothe their conscience for eating something they feel they should not, or as their only sustenance. Bulimics binge on alcohol for emotional reasons and then purge by vomiting it back up.
Our current culture's obsession with thinness, coupled with widespread acceptance of drug and alcohol abuse, have made this combination particularly attractive. Dr. Doug Bunnell, former president of the National Eating Disorders Association, said, "Binge drinking is almost cool and hip, and losing weight and being thin is a cultural imperative for young women in America. Mixing both is not surprising, and it has reached a tipping point in terms of public awareness."
Some experts are beginning to explore the possible psychological and neurological links between eating disorders and substance abuse. Does eating or binging somehow trigger the same pleasure centers as drugs or alcohol? Another avenue being explored is what to do if a person has both conditions. Treatment for addiction is abstinence, but no one can abstain completely from food. As Dr. Kevin Wandler, vice president for medical services at an eating disorders center, phrases it, "Eating normally would be an effective behavior, but it's easier to give up alcohol and drugs because you never need them again. If your drug is food, that's a challenge."
Question 5 of 5
What is the meaning of the word 'abstain' as used in the last paragraph?
Correct Answer: B
Rationale: In the context of the passage, 'abstain' means to refrain from or go without. The passage discusses the challenges of treating individuals with both eating disorders and substance abuse issues. It mentions that while treatment for addiction involves abstinence, it is not possible to completely abstain from food. This highlights the meaning of 'abstain' as 'go without' in this context. The other choices are incorrect: 'Dishonor' does not relate to abstain, 'Connect to' is not synonymous with abstain, and 'Liberate' does not align with the context of the passage.
