The next time you cozy up to your laptop in hopes it’ll lull you to sleep with ep after ep of Laguna Beach, you may want to reconsider: a new study connects exposure to blue computer lights during sleep to depression.
The study found that nocturnal exposure to blue wavelength lights found in computers, tablets and smartphones induced depressive responses and altered neuronal structures in hamsters, Dvice reports.
This begs the question, what do hamsters do when they’re depressed? Walk listlessly on their spinning exercise wheel? Refuse their dry oatmeal food? And what kinds of websites do hamsters cruise before bed?
Either way, to combat depression in hamsters and humans alike, the researchers suggest the use of red lights at night instead, Dvice reports. They also point out that studies have linked blue light to sleep deprivation before, but “the addition of mood-altering effects to the equation could make this an even more serious health concern, particularly for those already suffering from depression due to other factors.”
But if you simply must spoon your laptop all night, an app called F.lux can switch your screen to a more sleep-inducing hue, Dvice says. Or, you know, you could just read a good, old-fashioned book before bed.
