When it comes to blue light, people should be concerned about its potential effect on their sleep more than anything else, reports The Seattle Times.
Another consequence of looking at your phone right before you go to sleep is that it can stimulate your brain. “Screen time is not conducive to sleep onset, not only due to light exposure, but because of the potentially activating nature of what you’re looking at,” says Dr. Nathaniel Watson, director of the UW Medicine Sleep Clinic and president of the American Academy of Sleep Medicine.
