Just reading this story in the Huffington Post:
Over half of Britons are sleep deprived new research has revealed, and computers, tablets and smartphones are partly to blame.
A survey indicates that more than 28 million people in the UK – almost six in ten of the population – are regularly getting no more than seven hours sleep a night.
It also shows that 78% of Britons are exposed to sleep-disruptive blue light from computer devices before going to bed.
Among 18 to 24-year-olds included in the 2,149 adults questioned, this figure rose to an astonishing 91%.
