【题目】阅读下面图文，简要回答所给问题。

Many people use their mobile phones as an alarm clock and more are used to returning messages before sleeping. However. these habits are becoming sleeping problems.

Several years ago, my boss used to stay up working on her mobile phone and got badly ill because of that. Now she always leaves her phone in another room at night. And she encourages friends to do so. “I sent each of my friends the same Christmas gift—an alarm clock so that they could stop using their phones as the alarm clock，” she said.

If your mobile phone wakes you up in the morning, it may also keep you up at night. A study in 2015 showed that people in mobile phone radiation(辐射) mostly had sleeping problems. And according to a Swedish study, more than half of young people feel like there must be phones around them. Most of them feel sorry for not returning messages. So they even have to reply to their friends before sleeping.

So what kind of people prefer to use mobile phones in their bedrooms? A recent study has shown that threequarter of people aged between 18 and 34 prefer to sleep with their phones near them. That number falls off a little in middle age, but only people aged 65 and the older are used to leaving the phone in another room while sleeping.
