People who spend more pre-bedtime hours using the Internet or watching television are more likely to report that they don't get enough sleep, even though they sleep almost as long as people who spend fewer pre-bedtime hours in front of a computer or television screen, survey findings show.
调查显示，睡前长时间上网或看电视的人称自己睡眠不足的几率更大，即使他们的睡眠时间与在睡前上网或看电视时间较短的人一样多。
"While many people use electronic media, such as the Internet, it should be noted that the longer media use before sleep can trigger (self-perceived) insufficient sleep," lead researcher Dr Nakamori Suganuma, of Osaka University, Japan, told the reporter.
首席研究员、日本大阪大学的菅沼中森在接受记者采访时说：“如今，很多人使用互联网等电子媒体，但应该注意的是，睡前长时间使用会导致（自我感觉的）睡眠不足。”
He and colleagues obtained data on self-perceived sleep problems and the use of electronic media prior to bedtime from a total of 5,875 Japanese respondents in two separate Internet-based surveys. Their findings are published in the journal Sleep and Biological Rhythms.

总体来看，有29%的轻度使用者（少于1.5小时）将使用电子媒体列为可能导致睡眠不足的原因。而有40%的中度使用者（1.5至3小时）和54%的重度使用者（3小时以上）持相同看法。

菅沼特别指出，“无论是年轻网民还是中老年网民，上网比看电视更会让他们感觉睡眠不足。”
Up to 38 percent of the respondents listed accessing the Internet far into the night as a possible cause for their sleep disturbance, while about 25 percent said watching television far into the night caused their sleep problems.
多达38%的受访者认为上网至深夜可能是睡眠不足的一个原因，25%的人说看电视看到很晚是出现睡眠问题的原因。
The findings suggest that while heavy computer and television use before bedtime has a small effect on sleep duration, it may have a more significant effect on "sleep demand and sleep quality," Suganuma notes.
