"I'm going to bed earlier tomorrow!" But no matter how we decide, there are still many chances that we break our promises.
This behavior is called "bedtime procrastination"(睡眠拖延症), and results from being short of self﹣control and our body clock.
Bedtime procrastination is a common problem. According to a study, Among 2, 400 people, 53 percent of them couldn't follow their sleeping time they had planned, delaying(推迟)it at least twice a week. They delayed bedtime not because they liked to stay up late, but they couldn't stop doing some other things.
Accordingly, People who usually have trouble resisting temptations(抵制诱惑) and adhering to their intentions(坚持己见) are more likely to delay going to bed.
However, scientists think being short of self﹣control is not the only problem. Our body clock also lays an important role when it comes to bedtime.
In order to check the influence of the body clock on sleep, scientists studied the sleep patterns (t模式)of 108 people. It was found that those who got up late are more likely to delay their bedtime than those who woke up early every morning.
And more surprisingly, night owls(夜猫子)would go to bed late at the very beginning of the weekday, even though they had to get up early for work and school. It's their special body clock that plays a part in delaying their bedtime.
People always think that bedtime procrastination isn't a big problem, but the choices we make that affect (影响)our sleep could finally be pretty important for our health.
Haiyan is 7 years old. Her parents gave her an iPad as a gift for her birthday. A month later,her eyesight(视力)dropped to 300 degrees. This is serious for such a young child.
Many children in China are facing the same problem: iPad using is bringing problems to their eyesight. The problem is so common that newspapers even call the iPad the "No. 1 killer of children's eyesight!"
"There are about 30 shortsighted children coming every day, "said Hu Dali, an eye doctor at Guiyang Aier Eye Hospital. "Half of those children have poor eyesight because they have played with phones and iPads for too long. "
Doctors and scientists say children's vision(视觉)is not yet fully developed and their eyes get tired more easily. The screen of an iPad uses very bright(明亮的)LED backlight. If children look at an iPad screen for a long time, their eyes do not have time to rest. This will make their eyesight worse over time.
Doctors advise that users should hold their iPads between 40-60 centimeters(厘米)away from them. The brightness of the screen should be comfortable for children. Parents should also stop their children from using an iPad for more than one hour every day.
