The number of sleep deprived Brits has risen by 50 per cent in a year as people increasingly use smartphones and computers before bed.
Nearly six in ten people in Britain now get seven hours of less sleep a night putting them at risk of cancer, diabetes and heart attacks, it has been warned.
Academics at the University of Hertfordshire found that 80 per cent of people are making it worse by using technology before sleeping which exposes them to disruptive blue light.
Blue light is present in morning light so late night gadget use can trick the body into speeding up the metabolism and making sleep more difficult.
