Blue Light Waves and the Brain

No doubt you noticed the band of blue light on the drawing of the electromagnetic spectrum. Blue light has one of the shortest and highest-energy wavelengths. Blue light waves are everywhere. Did you ever wonder the reason the sky looks blue? When the sun’s rays travel through the atmosphere, the high-energy blue waves crash into the air molecules, scattering blue light everywhere. Blue light waves from the sun helps you feel alert, be in a pleasant mood, strengthen your immune system, and regulate your circadian rhythm. When you are out of doors, you can be exposed to blue light wherever the sun’s rays can reach you.
