Computer screens produce blue light that we can see them even on sunny days. But at night, this brightness mixed signals to the brain about what time is bedtime. The brain stops producing melatonin, a hormone that gives your body the “time to sleep” cues, and throws your circadian rhythm out of whack. Over time, not getting enough sleep can lead to a buildup of neurotoxins that make it even more challenging to doze off.
