Insomnia spreads among young Chinese

The incidence of sleep disorder in the country is 38.2 percent, well above the international level. Yang Zekun reports.

"I kept telling myself to sleep, but it didn't work, my eyes stayed open until 5 am," said Perinur Ewel, a second-year postgraduate student at China Agricultural University in Beijing.

Perinur, who has been having problems sleeping for over six years, often sleeps at 4 am or 5 am. Before that she's wide-awake, even though she can feel her physical tiredness - the result of getting by on five or six hours of sleep a day.
