The late night viewing of television, computers and smartphones / tablets is problematic. The type of light is disrupting our sleeping patterns which removes the opportunity for the body to properly rest and restore itself.
The issue seems to be the high levels of blue light produced by our LED screens. While bright and easy to see, the unintended side-effect is that the bright light mimics daylight and tells us to wake-up.
There are some simple solutions that automatically dim your screens and change the temperature of the colors to remove the offending blue.
