Sleep hygiene refers to a set of simple daily habits that ①helps the body prepare for consistent, restorative rest. Experts commonly recommend going to bed and waking up at the same time every day, even on weekends, because an irregular schedule confuses the body's internal clock and makes it ②harder to fall asleep on demand. They also advise reserving the bedroom for sleep alone, since using the bed to study, scroll through a phone, or watch videos teaches the brain ③to associate that space with wakeful activity rather than rest. Physical environment matters as well: a cool, dark, and quiet room tends ④to produce deeper sleep than one that is warm, bright, or noisy. None of these individual habits guarantees a good night's sleep on its own, but together they form a routine that gradually trains the body to expect and enter sleep more easily, much the way a consistent set of cues trains an athlete's body ⑤to perform at a certain time each day.

As consumers become more aware of global social and environmental issues, many now expect companies ①to take responsibility beyond simply selling products. This expectation has given rise to ethical consumption, in which shoppers consider factors such as fair wages, humane treatment of animals, and environmental sustainability before making purchases. Companies that ignore these concerns risk public backlash, especially when unethical practices are exposed through investigative journalism or social media. Some corporations have responded by publishing detailed sustainability reports, though critics ②questions whether these documents reflect genuine change or merely serve as public relations tools. Real accountability, according to many experts, ③requires independent verification rather than self-reported claims that cannot be easily checked. Consumers, for their part, must also ④remain vigilant, since a company's marketing language does not always ⑤match its actual practices.

Researchers who ①study teenagers have found a strong link between how well students sleep and how well they perform in school. Students who sleep fewer than seven hours a night tend to score lower on tests of memory and attention than those who ②sleep eight or nine hours, even when the two groups study for the same number of hours. One explanation is that sleep plays an active role in learning: during certain stages of sleep, the brain replays and strengthens information ③encountered during the day, converting fragile short-term memories into more durable long-term ones. When sleep is cut short, this consolidation process is interrupted before it can finish, so material that seemed well understood the night before often ④feel unfamiliar the next morning. For this reason, some schools have begun rethinking early start times, reasoning that an extra hour of sleep might do more for test scores than an extra hour of studying ever ⑤could.

Influencer marketing has become one of the most powerful tools that companies use to reach young consumers. Unlike traditional advertisements, which often feel distant and impersonal, posts created by influencers seem more like advice from a trusted friend. This sense of closeness, built through years of sharing daily life online, makes followers more willing to trust product recommendations than ordinary commercials. For example, a skincare brand promoted by a popular lifestyle influencer can sell out within hours simply because her audience believes her opinions are honest. Consumers are becoming more ①careless, checking whether reviews are sponsored before making a purchase. In the end, influencer marketing works best when it ②stays ③grounded in ④authenticity rather than mere ⑤popularity.

Travelers who cross several time zones in a single flight often arrive feeling exhausted, foggy, and strangely out of sync with the local clock, a condition widely known as jet lag. The discomfort arises because the body's internal clock continues to run on the schedule of the departure city even after landing. Realigning this internal clock to a new time zone is not instantaneous; researchers estimate that the body typically needs about one day to adjust for every time zone crossed. Flying eastward tends to produce more severe symptoms than flying westward, because _______________. Exposure to natural light at the right moments after arrival can help speed up the adjustment, since light is the strongest external cue the internal clock uses to reset itself.

Limited-edition products are goods that are released in small quantities for a short period of time. Many companies use this strategy because ___________. When consumers believe that a product will disappear soon, they often feel pressured to buy it immediately rather than wait. For instance, a sneaker company that releases only a few thousand pairs of a special design can generate long lines outside stores overnight. This excitement is intensified by social media, where people proudly share photos of items that others could not obtain. However, this psychological pressure can lead to purchases that are driven by fear rather than genuine need. As a result, some shoppers later regret spending money on products they rarely use afterward.

Jina used to fill her apartment with items she rarely used, believing that owning more things would make her happier. After moving twice within a single year, she grew exhausted from packing boxes filled with clothes she had never worn and gadgets she had forgotten she owned. Frustrated, she decided to try a minimalist lifestyle, keeping only objects that served a clear purpose or brought her genuine joy. Gradually, however, she noticed that her small apartment felt calmer and easier to manage. She also realized that she spent significantly less money once she stopped buying things impulsively to fill emotional gaps. Inspired by her experience, several of her friends began adopting similar habits, questioning purchases they once made without thinking. Jina's story reflects ___________.

Modern sports wearables, from wrist-worn fitness trackers to smart insoles, continuously collect data that would once have required a laboratory to measure. (A) However, the flood of data has also created a new challenge, since distinguishing a meaningful pattern from ordinary daily fluctuation requires expertise that many amateur athletes simply do not have. (B) Coaches use this constant stream of information to detect early warning signs of overtraining, sometimes noticing a decline in performance before the athlete consciously feels tired. (C) Because of this, many teams now rely on wearable data as a routine part of daily monitoring, checking it as automatically as they once checked a stopwatch.

This connection is not merely correlational; sleep appears to directly supply the raw materials the immune system needs. When the body fights off an infection, the immune system relies heavily on adequate sleep to function effectively. ( ① ) During deep sleep, the body produces and releases cytokines, proteins that help regulate immune responses and coordinate the fight against harmful invaders such as viruses and bacteria. ( ② ) People who consistently sleep fewer than six hours a night show measurably weaker antibody responses after vaccination compared with those who sleep seven or eight hours, suggesting that sleep loss can blunt the immune system's ability to build lasting protection. ( ③ ) Chronic sleep deprivation also appears to promote low-grade inflammation throughout the body, a state that, over time, has been linked to a higher risk of heart disease and other chronic conditions. ( ④ ) Rather than being a passive state in which the body simply rests, sleep functions as an active period during which the immune system repairs itself and prepares for future threats. ( ⑤ ) This is why doctors often recommend extra sleep, not just medication, when someone is fighting an illness.

주어진 문장: In reality, however, that "original" price was sometimes never actually charged to any customer. Retailers frequently rely on sales events to boost short-term revenue, but the psychology behind these promotions is more complex than simple discounting. ( ① ) When a price is crossed out and replaced with a lower number, consumers instinctively perceive the new price as a bargain. ( ② ) This technique, known as anchoring, shapes how shoppers judge value by comparing prices rather than evaluating a product on its own merits. ( ③ ) Limited-time sales further intensify this effect, since a ticking clock encourages rushed decisions that leave little room for careful comparison. ( ④ ) Retailers also use phrases such as "while supplies last" to suggest scarcity, even when inventory remains plentiful. ( ⑤ ) Over time, frequent sales can actually train customers to wait for discounts rather than buy at full price.
