Press/Media: Research


Visual displays which may stop us from feeling sleepy, can be redesigned to give us all a well-earned rest, say scientists from the Universities of Manchester and Basel.

The team led by Professor Rob Lucas and Dr Annette Allen from The University of Manchester today unveil new technology which could revolutionise displays in televisions, smartphones, projectors, computer screens and tablets.

    DescriptionThe colour cyan - between green and blue - is a hidden factor in encouraging or preventing sleep, according to biologists.

    University of Manchester researchers say higher levels of cyan keep people awake, while reducing cyan is associated with helping sleep.

    The impact was felt even if colour changes were not visible to the eye.

    The researchers want to produce devices for computer screens and phones that could increase or decrease cyan levels.

    DescriptionChanging the colours given off by screens could combat both daytime sleepiness and nighttime insomnia, new research suggests.

    Mobiles, TVs and computers display the three primary colours red, yellow and blue.

    Adding a fourth turquoise hue tricks the brain into thinking it is daytime, causing screen users to feel more alert, a study found today.

    Turning down this colour makes people feel sleepy and could help them nod off, the research adds.

    Study author Professor Rob Lucas, from The University of Manchester, said: 'Such displays could, for example, help phone obsessed teenagers to fall asleep, or support alertness in people who need to use a computer at night.'
