43.You may know about "junk food" like French fries.But do you know about "junk sleep"? A British survey shows that there are many electronic products in teenagers' bedrooms.They are influencing teenagers' sleep badly. The survey was done among 1,000 British kids from 12 to 16.It is found that 50% of them got just 4 to 7 hours' sleep every day.But doctors say they need 8 to 9 hours. Almost 25% of the kids said they often fell asleep while they were watching TV,listening to music or using other electronic products. "This is very worrying," said Dr.Chris,a British professor (教授). "We call it 'junk sleep'.It means you don't get enough sleep and the quality (質量) of the sleep is low,too." The survey found that quite a few of the kids felt tired each day because of the junk sleep,especially girls between 13 and 16.Nearly all the teenagers have a phone,music player or TV in their bedrooms.And lots of them even have all the three. Dr.Chris suggested that parents should help their children keep away from electronic products,and that teenagers should spend less time on the electronic products.
