This raises serious questions about whether being short of sleep is influencing children's ability to pay attention at school． Research has shown that losing even just half an hour's sleep at night can have deep influences on how children perform the next day．
So why aren't teenagers getting enough sleep？Some experts suggest that televisions， computers and mobile phones in children's bedrooms may cause problems．Instead of reading a book at bedtime，children are playing computer games，surfing the web，sending messages， or watching television．As these new pre-sleep activities have become more common，more traditional ones such as reading have become less，Dr．Luci Wiggs，a researcher at Oxford
University's Section of Child and Adolescent Psychiatry said，“One of the problems with these pre-sleep activities is that they do not have clear start and end times which leads to being short of sleep．”
Research has shown that teenagers have different sleep patterns from adults．Human bodies produce melatonin（褪黑激素）to help fall asleep． Most adults start to produce melatonin at
about 10 pm，while teenagers only begin to produce it three hours later．It is possible that this delay in melatonin production is caused by the behaviors of teenagers such as playing with phones late at night．
Problems about sleep- who needs how much and when -are usually connected to students' achievements． But modern brain researchers say it is time that more schools wake up to both biological and social facts and make a better timetable for their teenager students．
