Lack of sleep puts Beijingers at risk

Children and teenagers in Beijing get less sleep than those in other parts of the country, putting them at a higher risk of physical and mental health problems, a report has warned.

Residents snooze 7.6 hours a night on average, but about 25 percent of the city population regularly gets insufficient sleep, according to the China sleep index released by the capital's Health and Family Planning Commission.

At least 30 percent survive on fewer than 6.5 hours a night, the report said.
