The Difference Between Natural and Artificial Blue Light
There are very short and high energy blue wavelengths from the sun and they collide with the air molecules causing blue light to scatter everywhere – this actually is what makes the sky appear blue.
In natural form the sun configures your circadian rhythm using blue light to control your sleep and wake cycles. It also helps raise alertness, increase reaction times, elevate your mood and boosts your feeling of well being.
Artificial sources of blue light include electronic devices such as cell phones and laptop computers, as well as energy-efficient fluorescent bulbs and LED lights. As technology has developed and more of our day to day lives revolve around this technology and screens, we have become more and more exposed to artificial blue light.
