The WHO says that 80% of the world’s teens don’t get enough exercise to live healthy lives. The report was based on research done with students aged 11 to 17 in 146 different countries.
Doctors say 60 minutes of exercise daily is needed for teens to build up their bone and muscle strength. It’s also hugely important for the health of the heart and lungs.
One big reason for the lack of activity in today’s teens is technology, such as smartphones, computers and TVs. Many teens find it hard to pull themselves away from them.
So the WHO warns that teens need to do less playing in the digital world, and more playing in the real world. Teens should take part in sports, whether on official teams or just playing around on the playground.

【推荐2】Walking, the world’s most natural exercise, is one of the best ways to keep healthy. It is less dangerous than running. Walking strengthens muscles without stretching them too much and it puts less pressure on bones and joints. Many people are active in what is called fitness walking. They take short walks a few times each week to improve their health. Fitness walking can be done in groups or alone almost anywhere and anytime. No special equipment is needed.
Experts advise drinking some water before and after each walk and also gently stretching the muscles and joints that are most likely to become tense during the exercise.
The most effective way to walk is the natural way. Keep your head high and your back straight. In fitness walking it is important to remember your footsteps should fall almost in a straight line. Bend your arms at elbows. Let them swing from the shoulders with each step.
Walking is good for the health of your body. And studies have provided details about the link between walking and your emotional health. A group of subjects were asked to describe their feelings of energy and tension before a ten-minute fast walk. When they returned, they felt less tired and more full of energy. This feeling lasted one hour. Even after 2 hours the students felt less tired than they had before the experiment.
Short walks can also help make personal problems seem less serious. One group of subjects described the seriousness of their personal problems such as job worries, or failing marriage. They went for a ten-minute fast walk. When they came back, they said their problems seemed less threatening. Improvements were not observed everyday, but after 3 weeks, the differences became very clear.

【推荐3】I’m a walker, logging an average of 9000 steps a day several times a week around my neighborhood. On recent trips to Copenhagen and Stockholm, I noticed tall, fit Scandinavians (斯堪法尼亚人) walking along on city streets with poles, as if they were cross-country skiing without any snow.
It was a surprise to learn that the addition of the poles makes it a more vigorous, full-body exercise than simply walking – and, as a 76-year-old looking to stay healthy while enjoying the outdoors, I decided to give it a try.
There’s plenty of help online for the new Nordic (北 欧的 ) walker: stand tall, swing your arms out as if to shake hands, and plant your poles with vigour. Then there’s the little matter of the strap (带子) on the pole. This allows the walker to grip the pole when thrusting forward and then relax that hand as the other hand pushes forward – a skill of coordination that builds stronger muscles.
For a warm-up, I started slow: Nordic walking down the hall that extends from my front door to the deck. Keeping balance wasn’t my only problem. The novel use of my arms and upper body was surprisingly demanding. After half an hour, my heart was pounding and I was sweating, but I still wasn’t much good.
Still, I carried on because there’s no arguing with the exercise’s benefits. Nordic walkers’ upper-body exercise increases their heart rate significantly more than walking without poles. And according to cardiologist Dr Aaron Baggish, with poles “you’re engaging 80 to 90 per cent of your muscles.” It also helps people with Parkinson’s, says Burrill. “We put poles in their hands and it’s amazing because they start walking with real rhythm.”
After a few clumsy days of being convinced I would never succeed, suddenly everything clicked. Not only was I able to coordinate the movements, I was aware that my heart, arms and core were getting a workout. Nordic walking is a form of exercise I expect to enjoy for years to come.

【推荐1】Children's average daily time spent watching television or using mobile device increased from 53 minutes at 12 months old to more than 150 minutes at 3 years old, according to an analysis by researchers at the National Institutes of Health. Children aged 7 were more likely to spend the highest amount of screen time if they had been in bad home-based childcare or were born to first-time mothers.
“Our results indicate that screen habits begin early,” said Edwina Yeung, an investigator in National Institute of Child Health and Human Development (NICHD), “This finding suggests that interventions to reduce screen time could have a better chance of success if introduced early.”
In the research, mothers of 4,000 children responded to questions on their kids' media habits when they were 12, 18, 24, 30, and 36 months of age.
The American Academy of Pediatrics recommends avoiding digital media exposure for children under 18 months of age, introducing children 18 to 24 months of age to screen media slowly, and limiting screen time to an hour a day for children from 2 to 5 years of age. In the current study, researchers found that 87% of the children had screen time exceeding these recommendations. However, while screen time increased throughout infancy, after 8 years of age, screen time fell to under 1. 5 hours per day. The researchers believe this decrease relates to time consumed by school-related activities.
The study authors classified the children into two groups based on how much their aver- age daily screen time increased from age 1 to age 3. The first group, 73% of the total, had the lower increase, from an average of nearly 51 minutes a day to nearly an hour and 47 minutes a day. The second group, 27% of the total, had the higher increase, from nearly 37 minutes of screen time a day to about 4 hours a day. Higher levels of parental education were associated with the lower odds of inclusion in the second group.

【推荐2】The Internet plays a big part in human life. We use it for work and pleasure. We use it to learn a new language. We find advice on it. We use it to connect with family and friends. We use it to stay in touch with events we care about. The list goes on and on.
Well, that train has left the station. This expression means there is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, researchers say. A new study finds that heavy Internet use may be connected to high blood pressure in an unlikely group: teenagers.
High blood pressure makes your heart and blood vessels work too hard. Over time, this extra pressure increases your risk of a heart attack. High blood pressure can also cause heart and kidney disease. It is also closely linked to a brain disease.
The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people, from 14 to 17 years old , took part in it. 134 of the teens were described as “heavy Internet users.” And researchers found that out of these 134 teens,26 had high blood pressure. The researchers say the study is the first to connect heavy web use with high blood pressure. Other research has connected heavy Internet use with anxiety, depression and obesity.
The lead researcher is Andrea Cassidy Bushrow. She said, “Using the Internet is part of our daily life, but it shouldn’t ruin us.” Ms. Cassidy Bushrow adds that it is important for teens to take regular breaks from their computers or smartphones and do some kind of physical activity. She also suggests that parents limit their children’s use of the Internet to two hours a day, five days a week.

【推荐3】Some in the Western media are sensationalizing the tepid response of Chinese consumers to new iPhone products, and some previously went so far as to suggest that China was imposing a ban on iPhones.
This doesn’t make sense. As a market economy, Chinese consumers have the right to choose from a competitive phone market.
At an event held on Wednesday, Apple Inc introduced its new series of iPhones, which come with new chips and new titanium shells and a USB-C charging cable. The iPhone 15 series comes after Huawei started selling its Mate 60 series and the Mate X5.
The launch of the two brands’ new phones generated different reactions from Chinese netizens. For example, the iPhone 15’s launch event was not on the most-searched lists of many popular Chinese online platforms such as Sina Weibo. In contrast, Huawei’s Mate 60 series was trending on Chinese social media platforms during its launch in late August.
Some researchers point out that there is absence of groundbreaking technological features in the new iPhone series; instead, they have been relying on brand loyalty to sell its smartphones. They also say that Huawei’s strong comeback gives users more choice, and will force Apple out of its comfort zone to improve its technology, although it has been the most purchased smartphone in China for years. According to market research company Counterpoint, Apple dominated the Chinese smartphone market with a share of 19.9 percent in the first quarter of 2023, followed by Chinese phone brands such as Oppo (18.3 percent), Vivo (17.7 percent), Honor (14.6 percent), Xiaomi(13.6 percent) and Huawei (9.2 percent).
This shows that the market share of Chinese brands is growing quickly. Among China’s more than 1 billion smartphone users, more than half are using middle-range handsets. They already have reasonable expectations for the money they will invest in electronic devices. They also attach great importance to innovative functions of smart phones that can cater to their individual needs. So the fact that a number of Chinese smartphone makers are rapidly catching up and even surpassing iPhone in certain features is really a good news for them. Plus most domestic-brand smartphones are within their reach.
The market share of smartphone brands in China clearly shows that smartphone sales are decided by market factors and not political factors. A spokesperson for the Chinese Foreign Ministry told a news conference on Wednesday that there are no laws, regulations or policy documents prohibiting the purchase and use of mobile phones of foreign brands such as Apple.
China is now the third-largest market for Apple, and has also been a growth engine and manufacturing hub for Apple for years now. It brings in roughly 20 percent of the US tech giant’s total revenue and is a key part of the supply chain for iPhones, MacBooks and other devices.
It’s time the Western media stopped churning out these “ban” stories.
