Using phone for a long time may cut down your lifespan, if a research is an indication.
Prolonged exposure to blue light, such as that which emanates from your phone, computer and household fixtures, could be affecting your longevity, even if it’s not shining in your eyes.
According to a research at Oregon State University, the blue wavelengths produced by light-emitting diodes damage cells in the brain as well as retinas.
The study involved a common fruit fly. The researchers studied how flies responded to daily 12-hour exposures to blue LED light — similar to the prevalent blue wavelength in devices like phones and tablets — and found that the light accelerated aging.
Flies subjected to daily cycles of 12 hours in light and 12 hours in darkness had shorter lives compared to flies kept in total darkness or those kept in light with the blue wavelengths filtered out. The flies exposed to blue light showed damage to their retinal cells and brain neurons and had impaired locomotion — the flies’ ability to climb the walls of their enclosures, a common behavior, was diminished.
Some of the flies in the experiment were mutants that do not develop eyes, and even those eyeless flies displayed brain damage and locomotion impairments, suggesting flies didn’t have to see the light to be harmed by it.
