Scientists have warned that the blue light emitted by Smartphone and Tablet PC screens is preventing millions of us from getting sufficient sleep each night – the young are unsurprisingly the worst affected.
Mobile phones and tablet PCs are apparently responsible for one of the worst insomnia epidemics the Western world has ever seen, though perhaps not for the reasons you’d expect. Sure we’re all guilty of staying up a little too late from time to time after getting hooked on a game, app or website, but this isn’t what doctors are most worried about.
Instead, it’s been suggested that the ‘blue light’ emitted by such devices has an effect on the brain which makes it much more difficult to get to sleep after powering down and turning off the lights. Unsurprisingly, it’s younger generation that are said to be the worst affected as they’re not exactly known for maintaining healthy sleep patterns anyway and are for the most part addicted to their devices.
In fact, research suggests that upward of 90% of youngsters don’t get as much sleep as their brains and bodies need.
As for the advice – switch off all such devices at least 120-minutes before going to bed…and yes, that does also include TVs and pretty much anything with a screen.
The problem derives from the way in which the blue light emitted by the screens plays havoc with the brain’s control over melatonin production – a hormone that helps send the individual to sleep. Worse still, millions are not only hampering their efforts to get to sleep by using such devices, but then also turn to their Smartphones and tablet PCs after finding themselves unable to sleep, thereby entering something of an unbreakable insomnia cycle.
Experts advise that along with avoiding all such screens before bed, it’s imperative not to be tempted to use any such devices if finding it difficult to sleep – you’ll only make matters worse for yourself!
