'Abandon laptop before bed'
Updated on 27 December 2007
Good news for insomniacs everywhere - experts have uncovered the secret to a good night's sleep.
Unfortunately for workaholics, it involves banning your mobile phone, BlackBerry and laptop computer from the bedroom for at least an hour before lights out.
"Checking your work emails before bed on any electronic device is essentially the equivalent to drinking a double espresso last thing at night," said Dr Chris Idzikowski, of the Edinburgh Sleep Centre.
"Research has shown that light from a laptop or Blackberry is concentrated enough to signal your brain to stop production of melatonin, a natural hormone known to aid sleep disturbances.
"Being in a relaxed environment and incorporating essential wind-down time into your day is your best chance of securing a great night's sleep - along with silence, darkness and comfort."
Work-related stress is one of the major factors when it comes to sleeping at night, with the average Briton suffering an estimated 55 nights of poor quality sleep a year.
Dr Idzikowski's survey was commissioned by the Crowne Plaza hotel chain.
A spokesman said: "The temptation to check emails late at night is potentially jeopardising business travellers' chances of securing a good night's sleep."
