The daylight is rich with blue light, which fully activates
the melanopsin and synchronizes the brain clock with the day.
It reduces sleepiness and depression and increases
alertness.
Foggy brain
We spend most of our time indoors, and frequently artificial light
is not rich in blue light, which sends a confusing signal to the
brain, that it is not day yet, so all the chemicals that would boost
our moods are not activated, and we feel tired and foggy.
Alertness and productivity
