It makes you more likely to get cataracts (白内障), among many other medical problems. If you’ve tried to kick the habit before only to start again, keep at it.

If you use dangerous materials on the job or at home, wear safety glasses. Sports like ice hockey, racquetball, and lacrosse can also lead to eye injury.

2 . Children at boarding school get the best night’s sleep because of strict lights out time, according to a recent study, which was presented at Sleep Down Under, the 33rd yearly scientific meeting of the Australasian Sleep Association. Professor Kurt Lushington, a psychologist who led the study; said, “It is a naturalistic experiment showing the key to good sleep in teenagers is quite simple: a good timetable and no mobile devices(设备) at night.”
Over the past 20 years, the time children spend sleeping has fallen and only half regularly get more than seven hours. The recommended amount is eight to ten. The biggest problems are smartphones and tablets (平板电脑) whose blue light wakes the brain, making it harder to drop off.
An Australian team compared sleep patterns of 15 to 18-year-olds at a school in Adelaide. The 59 boarders had to leave their phones in a kitchen area or on their desk before bed and turn their lights out by a set time. They slept for an average 8 hour 26 minutes a night compared with 7 hours 46 minutes for day pupils.
Lack of sleep affects mental health and school performance and causes behavioral problems. It has also been connected with the child obesity epidemic and other diseases. This year an American study found that teenagers who didn’t get enough sleep took in extra sugar during a school year. They ate sweets, cakes, chocolate and biscuits and drank fizzy drinks to promote their energy levels.
Lushington recommends that parents reach agreement on not using a phone. This is most likely to work if they do likewise and offer other enjoyments, such as books. “I think if you put these rules in place, kids will go along with them,” he told New Scientist.

3 . When I was a child, I always wanted to be a superhero. I wanted to save the world and make everyone happy. But I knew that I’d need superpowers to make my dreams come true. So I used to embark on these imaginary journeys to find intergalactic (星系之间的) objects from planet Krypton, but didn’t yield much result. When I grew up and realized that science fiction was not a good source for superpowers, I decided instead to embark on a journey of real science, to find a more useful truth.
I started my journey in California, with a UC Berkeley 30-year longitudinal study that examined the photos of students in an old yearbook, and tried to measure their success and well-being throughout their life.By measuring the students’ smiles, researchers were able to predict how fulfilling and long-lasting a subject’s marriage would be, how well they would score on standardized tests of well-being, and how inspiring they would be to others.
Another aha moment came from a 2010 Wayne State University span research project that looked into pre-1950s baseball cards of Major League players. The researchers found that the span of a player’s smile could actually assist to predict the span of his life. Players who didn’t smile in their pictures lived an average of only 72.9 years, while players with beaming smiles lived an average of almost 80 years.
British researchers found that one smile can generate the same level of brain stimulation as up to 2,000 bars of chocolate. Wait — The same study found that smiling is as stimulating as receiving up to £16,000 in cash. That’s like $25,000 a smile. It’s not bad. And think about it this way: 25,000 times 400 — children smile as many as 400 times per day — quite a few kids out there feel like Mark Zuckerberg every day.
So whenever you want to tap into a superpower that will help you and everyone around you live a longer, healthier, happier life, smile.

5 . Smartwatches and fitness trackers (健身追踪器) have gained popularity recently. These tools can record your daily steps, heart rates, etc.
It’s a struggle to overcome the addiction to fitness trackers.
Of course, failing to meet your daily goal can be discouraging. You might focus on your shortcoming rather than your progress. Another problem is that you might find yourself paying too much attention to the step number rather than how your body feels.

A.How can you tell whether you’re addicted to your fitness tracker? |
B.Actually this addiction to step count can be risky, mentally and physically. |
C.Don’t overuse your smartwatch. |
D.However, do you find yourself checking your steps and heart rates too often? |
E.After all, reaching a daily step count can be so appealing. |
F.Besides, you can find other things to do that don’t involve checking your fitness tracker. |

6 . Parkinson’s is a progressive brain disease which leads to shaky hands and slow movement, and there is no cure. Tai Chi, a traditional Chinese martial art that combines (结合) slow, gentle movements with deep breathing and relaxation, may be an effective means of reducing the suffering. Recently, the researchers say that those who practised the martial art twice a week had fewer complications (并发症) and better quality of life than those who didn’t. Experts say the findings back up previous studies on the benefits of exercise for those with Parkinson’s.
The study, from Shanghai Jiao Tong University School of Medicine, monitored the health of hundreds of Parkinson’s patients for up to five years. One group of 147 people practised regular Tai Chi while another group of 187 did not. The researchers found that the disease progressed more slowly in the Tai Chi group on measurements of symptoms (症状), movement and balance. This group also saw fewer falls, less back pain and dizziness, with memory and concentration problems also lower than in the other group. At the same time, sleep and quality of life continuously improved.
Prof. Alastair Noyce, professor in neurology and neuroepidemiology at Queen Mary University of London, called it “an important study”—the positive effects on aspects of motor (运动的) and non-motor functions are impressive — but said there were limitations in its design, and more tests were needed.
“We already recommend Tai Chi, as well as other forms of exercise, but understanding which forms of exercise are most beneficial is an important goal to improve the long-term management of patients,” he said.

10 . It’s December and there’s a definite chill in the air. The last thing you probably feel like doing in winter is opening a window, turning down the central heating and shifting workouts from a warm, cosy gym to the outdoors.
Hop off the treadmill (跑步机) and head outdoors for a greater fitness effect. Cold as it seems outdoors, running, cycling or walking in winter not only are good for you, but also make you feel easier once you get moving. Provided conditions are not freezing, our bodies tend to respond positively to colder weather workouts. Compared with exercising in the heat, there is less stress on the heart.
Cool your bedroom to burn extra calories and sleep well. Underfloor heating and a quilt might make your bedroom feel cosy but they won’t help you sleep.
Turn down the central heating to improve your blood sugar control. Studies have shown how repeated exposure to colder temperatures removes sugar from the blood quickly, a risk factor for diabetes (糖尿病).
A.Take an outdoor dip to relieve stress. |
B.Therefore, it is likely to feel less of an effort. |
C.Neither will they better your health and fat-burning potential. |
D.The key is not to lower the temperature by several degrees suddenly. |
E.Take a cold shower to boost your mood and support your immune system. |
F.But embracing, rather than avoiding cold temperatures, can enhance health. |
G.Being so uncomfortably cold that we shake is not required for a health boost. |
