According to this article, physically sleeping near your phone can make it harder for you to fall asleep! This can happen even if you are not using it (and therefore not exposed to the blue light that affects melatonin production). The mobile radiation emitted by our phones can affect our body's ability to fall asleep. Additionally, we feel a sense of obligation to respond to texts or emails if we hear our phone buzz even though we should be unplugged and asleep.

Exposure can cause problems falling asleep (because it does increase alertness), but this article showed a positive side to the blue light.
