New research shows that 70 per cent of adults check Facebook and Twitter before they go to sleep at night.
An average of 16 minutes is spent on social network sites between the sheets.
The study conducted on behalf of Travelodge, questions 6,000 adults, it found that 18 per cent send a daily night time Tweet to their followers. But there is a warning about the effect that this is having on your sleep.
Sleep specialist Dr Michael Hastings, researcher for the Medical Research Council at Addenbrooke's Hospital in Cambridgeshire told Press Association: “It's having a huge effect on people's sleep. Adults don't realise what impact using computers, mobile phones and other gadgets before falling sleep is having on their night's sleep.
“Being exposed to bright light from computer and mobile phone screens while in bed completely delays the brain and body's ability to get to sleep as quickly as they should and aren't getting the required amount of sleep they need each night.”
The research found that a quarter of Britons do their weekly online shopping in bed, before losing out on some of the 7.5 hours of required sleep they need.
It seems that we are to be rid of the dreaded alarm clock as well, as 84 per cent of adults now use their mobile phones to wake them up.
