SLEEP:
Developing muscle growth is an effective way to stay healthy as we get older, but many people find it difficult to develop this muscle growth, even after modifying their exercise routine and food intake. What many people may not realize is that getting the proper amount of uninterrupted sleep plays a major role in the development of muscle. The hard work of developing muscle is done in the gym, on a track, or on the court, but the actual growth takes place during the rest periods that follow a workout. Your body immediately begins rebuilding the muscle fibers that were broken down during the course of your workout. Much of this process is carried out while you are sleeping, so without a full night of sleep, muscle fibers will not have the opportunity to rebuild.
Human growth hormone (HGH) is an amino acid that is central to regulating metabolism, building muscle, facilitating calcium retention, and stimulating the immune system. The amount of HGH in your body spikes significantly during deep sleep, which makes getting at least 7 to 10 hours of sleep every night imperative to anyone hoping to develop additional muscle growth. Recent studies have linked inadequate amounts of sleep to lowered levels of leptin, a hormone in the brain that controls appetite. Test subjects who received less sleep, or frequently interrupted sleep, would crave carbohydrates even after their caloric needs reached satiety. This can contribute to obesity and negatively affect any good habits people may have developed with regard to food intake.
Question 1 of 5
What conclusion can the reader draw after reading the passage about The Sleep Workout?
Correct Answer: B
Rationale: The correct answer is B because the passage highlights that insufficient sleep could lead to an increased risk of obesity. The passage emphasizes the importance of uninterrupted sleep in muscle development and mentions that inadequate sleep is linked to lowered levels of leptin, a hormone that controls appetite. This imbalance in leptin due to lack of sleep can lead to increased cravings for carbohydrates, contributing to obesity.
Choice A is incorrect as the passage stresses the significance of both uninterrupted sleep and getting enough sleep for muscle growth.
Choice C is incorrect because the passage clearly states that human growth hormone (HGH) is essential for muscle development.
Choice D is incorrect as leptin is not essential for building muscle but is mentioned in the passage as a hormone related to controlling appetite and its link to inadequate sleep and obesity.

SUNLIGHT:
Most people are familiar with the damaging effects of the sun on unprotected skin, but not enough attention is paid to the many positive effects of receiving direct exposure to sunlight on a regular basis. The most compelling argument for increased exposure to sunlight is the need for vitamin D in the human body. Vitamin D is integral for maintaining healthy bones and preventing diseases like rickets and osteoporosis. It is synthesized by the skin when it comes into contact with the UVB rays found in sunlight. In order to ensure you are receiving the proper amount of vitamin D, it is recommended to get 15 minutes of direct exposure to sunlight at least two or three times a week. UVB rays are made less intense when passing through clouds and pollution, and they will not transmit through glass or sunscreen. UVB rays are also less effective the farther you are from the equator. People with darker skin require more exposure to the sun to receive the same amount of vitamin D.
In addition to vitamin D, sunlight will help regulate the circadian rhythms that ensure you get a good night’s sleep. Sunlight helps to prevent an overactive immune system, which may prove useful in preventing autoimmune diseases like psoriasis and lupus. Recent studies have even shown that sunlight can help lessen the symptoms of Alzheimer’s disease. The negative impacts of excess exposure to sunlight should not be ignored; cancers resulting from skin damage are a real concern that must be taken seriously. But the importance of vitamin D and the other positive impacts of sunlight make a compelling argument for making sure we are spending enough time every week in direct sunlight.

CONCUSSIONS:
A concussion is a traumatic injury to the brain that can interfere with the way the brain processes information and functions. A concussion often results in severe headaches, diminished alertness, and even unconsciousness. While more than one million people in the United States suffer concussions every year, many believe that, like people, no two concussions are identical.
Recently, two professional baseball players suffered concussions. The first player was injured early in the season and tried twice to return to regular play but was not medically cleared to play until the following year. Even after eight months, this player reported a recurring condition of “fogginess” that seemed to linger. The second player had brief symptoms of sleepiness and involuntary movement, or “shakiness.” A few days later, and after several tests, the second player reported that the effects of the concussion had subsided, and he was cleared to play.
No matter the duration of a person’s recovery, refraining from trying to do too much, too soon is vital. A specialist at Boston University’s Center for the Study of Traumatic Encephalopathy believes that someone who suffers a second concussion while still recovering from the first risks an even longer recovery. Full recovery from concussions is possible. Problems are seldom permanent, and for most people who have had a concussion, the long-term prognosis is typically excellent. The first baseball player recently returned to his team. And though he was told by his physician that he has no greater risk than anyone else of suffering another concussion, other physicians believe that suffering one sports-related concussion increases the likelihood of suffering another.

Evolution of the CDC:
The Centers for Disease Control and Prevention (CDC) started in 1946 as the Communicable Disease Center (CDC). Its original goal was to stop malaria in the United States. From a small office in Atlanta, health workers spread out over the South, spraying mosquitoes and using shovels to eliminate low spots of standing water. At that time, most of the CDC’s workers were not doctors; the need was for entomologists and engineers. The founder of the CDC, Dr. Joseph Mountin, enlarged the organization’s mission to fight communicable diseases of all kinds, and over the next 20 years, the CDC would focus on smallpox, measles, and polio.
In 1970, the name was changed to the Center for Disease Control, but the mission continued to expand. By 1980, the CDC was working not only on the eradication of existing diseases but also on disease prevention. By this point, it had hundreds of doctors and researchers looking into health problems such as depression and addiction. The name changed again, to the Centers for Disease Control and Prevention. Today, the CDC has thousands of employees and coordinates research activities with public health agencies worldwide. It is especially known for its work to protect people from epidemics and unexpected health threats, but its everyday work in the areas of environmental health, injury prevention, birth defects, healthy schools and workplaces, and health education is just as important and beneficial to all Americans.

Question 5 of 5
What is the main idea of the passage about The Sleep Workout?
Correct Answer: C
Rationale: The main idea of the passage is that getting the proper amount of uninterrupted sleep plays a major role in the development of muscle. The passage emphasizes how muscle growth occurs during rest periods following a workout, with sleep being a critical time for muscle fiber rebuilding. The connection between sleep, human growth hormone (HGH) release, and muscle development is highlighted.
Choice A is incorrect because while the passage mentions the link between inadequate sleep and obesity due to altered appetite hormones, the main focus is on muscle development.
Choice B is incorrect because although the passage discusses HGH release during deep sleep, the primary emphasis is on the role of uninterrupted sleep in muscle development.
Choice D is incorrect because while the passage acknowledges that developing muscle growth is essential for health as we age, the key point is the significance of uninterrupted sleep in the muscle development process.
