A new study in the journal Aging and Mechanisms of Disease suggests exposure to light emitted by digital devices and screens could have a damaging effect on brain cells. Oregon State University researchers exposed fruit flies to 12 hours of blue light and discovered it dramatically reduced their lifespan. The glow also impacted the brains of blind flies, suggesting there's no need to actually see the light to be negatively affected by it.
Should we be worried? Although brain cells in flies and humans function in a similar way, LED technology hasn't been widely used for long enough to know its health effects yet.
