So I have heard that to much exposure to specifically blue light can make it harder to sleep but how?I mean it’s light and blue is seen as a calming color so how can exposure to to much blue light make it harder to sleep?
In: Biology
Our waking and sleeping cycles are regulated by a variety of factors.
One of those factors is the colour of the light that we are being exposed to. A natural lifestyle would mostly involve getting up when the Sun rises and going to bed when the Sun goes down.
The light from the Sun seems reddish at dawn and dusk but bluer during the middle of the day. Our brains are programmed to take those cues to determine when the day begins and ends.
Blue light from phones and other devices fools our brains into thinking that it’s still daytime.
