After only one hour of nighttime exposure to LED blue light, the experimental animals chose a sugary rather than a balanced diet the following day and their glucose tolerance diminished.  This  study indicates that repetitive exposure to images at the blue end of the spectrum will drive snacking on sugary foods and interfere with our bodies’ abilities to process that extraneous sugar by increasing insulin resistance leading to diabetes. You can fight this tendency by using a setting on your iPhone called Night Shift and comparable TV screen settings that warm the screen colors from blue to orange.  Don’t be a slave to advertisers who may be using blue images to drive you to your junk food cabinet.
