Doom-scrolling for hours every day on social media? Think again – it could be turning your hair grey and giving you wrinkles. Scientists have found that the specific type of light emitted by mobiles may trigger premature ageing, including hair loss, wrinkles, and circles around the eyes. The problem stems from the light-emitting diodes, or LEDs, within the display screens of modern smartphones which produce high-energy visible light – often known as ‘blue light’ – to create bright colours. While some previous research has suggested blue light may be linked to premature skin ageing, associations between LED devices generally and ageing have not previously been investigated.
