LONDON, November 17, 2016 /PRNewswire/ -- Regional Stats Available Research published today says technology and our need to stay 'constantly connected' is causing Brits to lose the art of falling asleep.

The study by bed experts Warren Evans found that we're glued to screens in the run-up to bed and the last thing we do in the bedroom is actually sleep, with more than a third (36%) of us admitting we turn on a screen in bed when we're trying to nod off. 50% of adults and a worrying 82% of 18-24 year olds take their mobile phone into bed with them. With 63% of this 'tech generation' in bed playing games, doing social media, sending work emails, and watching TV - these are all distractions and cause problems when it comes to falling asleep. Almost half (40%) of adults take more than 20 minutes to fall asleep and 1 in 10 Brits aged between 18 and 24 are struggling for around an hour. The research also showed that stress appears the be the main factor affecting a decent night's sleep in the UK - half of us say that it keeps us from falling asleep initially, with a third of Brits then woken up by their worries during the night. Four out of ten Brits (38%) are waking up tired at least six days a week, with 15% saying they feel groggy every single morning. Sleep experts say we need to put our technology to bed an hour before ourselves and get back to the times when our days were more closely aligned to the natural cycle of light and dark.
