00:00 After years of being warned about the blue light on our phones and its potentially detrimental
00:05 effects on our sleep before bedtime, experts now say that theory could be wrong.
00:11 Researchers in Switzerland and the Max Planck Institute for Biological Cybernetics in Germany
00:16 recently found that, contrary to popular belief, blue lights may not be the biggest problem
00:22 when it comes to getting rest.
00:24 One of the leaders of the study said, "Yellowish light has a stronger influence on the internal
00:29 clock than bluish light."
00:30 The team studied eight men and eight women over 23 days to see how light affected people's
00:35 sleep and found "there was no conclusive evidence that blue light was any more damaging
00:41 to people's sleep than any other light."
00:44 In fact, the study suggests that brightness matters more than the hue of the light involved.
00:49 So if you scroll endlessly at 3 a.m., experts say, just try to keep your screens as dim
00:54 as possible.
