A member asked:
Why does blue light from our computer and smart phones negatively affect our sleep?
A doctor has provided 1 answer
Tricks: The blue light tricks our brain into thinking it is not really nighttime and we should feel more awake. It's similar to the blue light boxes sold for seasonal affective disorder and also used to treat circadian rhythm sleep disorders.
