Multiple studies have been done in recent years to show the effects of blue light on humans. All of them have shown that the brightness of the light, combined with the length at which phones and tablets are typically used, is preventing you from getting a good night’s rest. It suppresses the production of melatonin, a hormone that promotes good sleep among other things.
Unfortunately, sleep is not the only thing you are missing out on because of blue light. Melatonin is an important hormone in the body and its suppression means you could experience nausea, dizziness and other unpleasant ailments. Some doctors have even commented that overexposure to blue light can cause the development of diabetes, obesity, heart disease and even cancer. Fortunately, there are ways to stop blue light from ruining your health. In addition to enjoying more sunlight and curbing your phone and tablet use, UK-based startup OcuShield provides screen protectors that block huge percentages of the harmful blue light in all your devices. With models for iPhones, iPads, Macbooks and various Samsung gear, being plugged in won’t cost you your heath any more. While the health risks are enough to make this technology interesting, the notable overuse of these devices in the world make it necessary. Studies have shown that one in four children use a smartphone, tablet or computer for three or more hours a day. Millennials are even worse, with nearly half of them using devices for longer than that. And while efforts to curb device usage seem to be a fruitless endeavor, OcuShield’s screen protector seems to be the only way to actually get some sleep these days.
