All visible light we see contains the entire color spectrum of the rainbow.
Within that spectrum are blue light waves, between 400-500nm.
Blue light signals our body that it is time to be awake. It energizes us and makes us more alert.
But at night, it supresses melatonin, the sleep hormone, disrupting our bodies sleep wake cycle.
