How does the screen color of your phone affect you at night?

Question

I’ve heard that blue light affects you negatively at night. What about other colors?

In: Biology

Answer 1

Your brain is programmed to associate yellow/orange light with sunrise and sunset (time to sleep) and blue light with daytime (time to be awake). Blue light inhibits the hormones that send you to sleep because up until the invention of electric lighting, the only time any animal would ever see blue light regularly is during the day and we evolved to be awake during the day.
