Strayer is a cognitive psychologist at the University of Utah who specializes in attention. His research shows that, when driving, using a phone can be as dangerous as drinking alcohol. [B] Strayer and other scientists warn against multitasking. When we do many things at the same time, Strayer says, our brain becomes tired easily. We make mistakes and lose focus. Yet multitasking is increasingly common, especially on a phone or computer. Dr. Gloria Mark, a digital media researcher, has found that people in the United States switch tasks on their computers 566 times a day. This type of multitasking is especially common among teenagers. On average, a teenager spends between 7 and 11 hours a day in front of a screen - doing homework, texting, watching videos - often all at the same time.[C] Phones, tablets, and laptops are all useful tools, and we may feel more productive when we use them. However, when we spend hours on digital devices - constantly switching between activities - our overall productivity decreases. Why?[D] Many digital activities require high levels of concentration. When we text or email someone, for example, or even play games, we have to focus. When we do this, our brain uses energy. When we multitask - which is hard for the brain to do - we use even more energy. Excessive multitasking reduces our ability to think clearly and creatively, and to remember information. This, in turn, can result in stress. [E] What is the best cure for our overstressed minds? David Strayer says the answer is simple: Spend some time in nature.A Natural Remedy[F] Strayer and other scientists are studying nature's effect on our brains and bodies. When we are in natural environments, the prefrontal cortex (the brain's control center) relaxes. Studies show that when people can see trees and grass, they are calmer and do better in school. Indeed, people even relax when they look at photos of nature. Consequently, they do better on different cognitive tasks.[G] Other psychologists are also studying "nature therapy." In a study at Chiba University in Japan, 84 subjects went for a 15-minute walk in seven different forests. The same number of people walked around different city centers. Researchers then took blood from each person. The forest walkers had a 16 percent decrease in the stress hormone cortisol. In addition, they had a 2 percent drop in blood pressure and a 4 percent drop in heart rate. All did better than the city walkers. Lead researcher Yoshifumi Miyazaki has an explanation for these results. Our bodies relax in pleasant, natural surroundings, he says. Humans evolved in that environment, not in places with tall buildings and lots of traffic.[H] Psychologist Stephen Kaplan and his colleagues have done similar research. In one study, people took a 50-minute walk in a public garden. In a test conducted afterwards, their short-term memory improved. When the same people walked on a city street, it did not.[I] Kaplan says it is the visual details in nature - sunsets, streams, butterflies - that reduce stress and mental fatigue. We enjoy them without having to concentrate on them. This allows our brains to rest and recover from the stresses of modern life. "Imagine a therapy that was readily available, and could improve your cognitive functioning at zero cost," Kaplan says. "It exists: it's called 'interacting with nature.'"What does we refer to in paragraph B?

For every person who argues that video games are no different from movies, television, or other visual forms of entertainment, there is another who argues that video games are an especially negative force for young people at a crucial stage of their development. As a result of these polarized1 opinions, it is difficult for people to know what the truth is. However, according to the research of experts who study the effects of video games, both sides of the debate are partially right. It is clear that video games can have both positive and negative effects on the young people who play them.[B] In recent years, several studies within the field of psychology have demonstrated that video games are able to benefit young people if played in moderation. Video games are fun and stimulating and, in turn, are able to maintain a young person's concentration for a longer period of time than other media. As a result, if there is something to be learned through the gaming experience (for example, information about a new geographical location), the video game can facilitate the growth of a young person's knowledge.[C] Interestingly, researchers have also learned that video games can help children and teenagers develop several skills that can be transferred to other areas of their life, including education. Fast-moving video games have been shown to improve reaction speed, hand-eye coordination, as well as the ability to recognize patterns. Because they also involve puzzles and the need for strategy, video games have also been linked with improved problem-solving skills. Finally, although some have suggested that video gamers often exhibit signs of loneliness, research has demonstrated that modern online video games have helped develop social skills, including team building and cooperation. [D] Despite these many benefits, however, one cannot ignore the fact that video games can have a highly negative effect on some children and teenagers. This is typically the case for those young people who are addicted to video games and, thus, play them excessively. [E] The first major downside of excessive video game playing is the negative effect it has on academic achievement. Research has made it clear that there is a direct correlation between the amount of time a young person spends playing video games and their performance in school. Quite simply, those who play more tend to receive lower grades. In one study, for instance, it was demonstrated that almost 50 percent of heavy gamers received poor test scores. This was much worse than the 25 percent of light gamers who also did poorly on their tests.[F] Much like television and Internet addiction, young people who become dependent on video games are also more likely to suffer from physical health problems. While some children and teenagers become obese2 from a lack of exercise, others develop constant fatigue due to a lack of sleep.[G] Based on the pros and cons discussed in this article, it should be clear to parents and guardians that there is no black and white answer to the question of whether video games are a positive or negative force for young people. While video games can facilitate the development of important skills, too much time on the screen can lead to severe negative side effects and even cancel out the benefits. Consequently, parents and guardians ought to focus on finding the right balance between too much gaming and no gaming at all.1 If an issue is polarized, there are different groups holding opposite opinions about it.2 If someone is obese, they are overweight to an unhealthy level.According to the writer, why do some young people feel tired because of gaming?

Furthermore, in those brief moments in which we are offline, we often make it a priority to get back online as quickly as possible. Indeed, one of the first pieces of information that anyone seeks when entering a cafe, hotel, or shopping mall is the Wi-Fi password.[B] Although there are many explanations about why we now have such a dependence on Internet connectivity, one of the primary reasons is our working lives. The thought of missing an important email from one of our colleagues or worse, the boss, is enough to make many of us incredibly anxious. As a result, many people have chosen to do whatever it takes to continuously stay in the loop. Connectivity in one's car and long-distance mobile Internet services have allowed us not to lose sleep over a missed message, even when on a camping trip 200 kilometers from the nearest town. [C] The problem that many people have realized, however, is that we are now losing sleep for other reasons. Being connected 24 hours a day has fundamentally altered our working hours. In the days before we carried the Internet in our pockets, one could expect to leave work at the office and return to it the next morning. By contrast, in our current age, evenings and weekends have become fair game.1 Some even admit to working on their holidays, answering emails from a beach in Maui. [D] Due to the mental strain that comes with this constant connectivity, a number of remedies have become popular. Some have engaged in "device detox"2 - for example, going far into the countryside for a weekend without their smartphones or laptops. Others have committed to different forms of therapy. Meditation3 and yoga, both of which focus on being in the present moment, have become popular forms of such therapeutic activity. [E] It must be said, however, that such remedies are only temporary escapes. Going into the countryside for the weekend without your laptop means facing a pile of emails on Monday morning. With meditation and yoga, the relief ends the second you leave the studio and get back on your phone. [F] It is because of these limitations that some individuals have decided to "downshift" their lives altogether. Rather than simply going into the countryside for a weekend getaway, a minority of individuals have decided to quit their jobs in the city and find slower paced work in rural areas. While some have taken up farming, others have decided to open up small businesses. Although these new surroundings have allowed these downshifters to disconnect to some extent, a life such as this does lead to a series of new problems. Leaving a good job in the city often results in lower income and less employment stability. Consequently, in order to be free from a life of excessively checking your phone, you may need to reduce your expectations regarding the type of lifestyle you want to live. [G] With such a large trade-off4 involved, it is fair to say that not everyone would be willing to downshift. For many, a bigger bank account is more than enough motivation to keep their eyes on their emails. 1 Something that is fair game is considered reasonable and acceptable.2 To detox means to get rid of things that are harmful to you.3 Meditation is the act of staying silent and calm for a period of time for spiritual reasons, or to relax.4 A trade-off is a balance between two things that are against each other in order to gain something else.Why does the writer think remedies such as weekend getaways and meditation are ineffective?
