Light is the magical stuff that surrounds us that we use to make use of our eyes and thus vision. The main light source we have is the sun which, at different times of the day and weather, we experience different intensities and colours.
We also have artificial lightings such as lightbulbs of all different shapes and sizes and even digital screens that all have their own colour and intensity characteristics.
Each colour of light has its own wavelength, and cooler colours such as blue and purple have a very short wavelength. But what does blue light actually do to your body?
Shorter wavelengths of light are known to suppress your body's natural release of the hormone Melatonin which is responsible for making your feel sleepy. Too much visual ingestion of blue light will actually keep you awake for much longer and even suppress your appetite.
