　　[2016·福州八中质检]The bed should be reserved as a place for sleep, but people tend to read an iPad a lot in bed before they go to sleep.

　　Charles Czeisler, a professor at Harvard Medical School, and his colleagues got a small group of people for an experiment. For five days in a row, the people read either a paper book or an iPad for four hours before sleep. Their sleep patterns were monitored all night. Before and after each trial period, the people took hourly blood tests to paint a day­long picture of just how much melatonin (褪黑激素) was in their blood at any given time.

　　When subjects read on the iPad as compared to the paper books, they reported feeling less sleepy at night and less active the following morning. People also took longer to fall asleep on the iPad nights, and the blood tests showed that their melatonin secretion (分泌) was delayed by an hour and a half.

　　The researchers conclude in today's journal article that given the rise of e­readers and the increasingly widespread use of e­things among children and adolescents, more research into the long­term consequences of these devices on health and safety is urgently needed. Czeisler and colleagues go on, in the research paper, to note：“Reading an iPad in bed may increase cancer risk.”
