You don’t need to be a scientist to know that a bright light glaring into your face moments before you try go to sleep isn’t really good for you.
But did you realise just how bad it actually is for you? Probably not.
Because smartphones emit ‘blue’ light to ensure they’re visible even on the sunniest of days (not that we have to worry much about that sort of thing here), our brain perceives them as a source of natural sunlight.
As a result of that, they suppress our bodies’ production of melotonin – the hormone that tells us that it’s time to go to sleep – meaning that our sleep cycle is, to use the technical term, fucked.
And that’s just the start of the problems, as you can see in the image below.
The infographic above, from this article TechInsider, really hammers home the myriad of ways that this can affect us aversely. So, once you’re done tweeting and Facebooking this article to all your friends, you really should switch off your smartphone and get some high-quality shut-eye.
