Sleep experts studying what it takes to get a good night's sleep have bad news for email addicts.

According to the research carried out on behalf of Crowne Plaza Hotels and Resorts, checking emails before going to bed has the equivalent effect on the body of drinking a double espresso.

Light from a mobile phone or laptop is intense enough to halt production of sleep-enhancing melatonin and experts have warned workers to log off and shut down at least an hour before going to bed.

Apparently, due to the increasing prevalence of PDAs, mobiles, laptops and Blackberries in today's world, business travellers are suffering when it comes to sleep.

Edinburgh Sleep Centre's Dr Chris Idzikowski commented: "Checking your e-mails before bed on any electronic device is essentially the equivalent to drinking a double espresso last thing at night. 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".
