Good night's sleep is all in the mind

People suffering from chronic sleeping disorders should pay more attention to their mental health if they want a better night's sleep, experts urged ahead of World Sleep Day on Saturday.

"Almost all patients I receive experience sleeping disorders," said Bai Xiaoli, a psychiatrist at Beijing Friendship Hospital.

"Many patients with sleep disorders were totally unaware of the fact that they suffer psychological or mental problems, which in fact are the major reason for their sleep disorder."
