Research shows blue lights, most often emitted by electronics and energy efficient light bulbs, can throw off the body’s biological clock, potentially wreaking havoc on your sleep patterns.
The American Medical Association issued a warning that nighttime lighting has potential carcinogenic effects related to melatonin suppression.
Medical experts also say certain diseases can be exacerbated by messing with circadian rhythm including obesity, diabetes, and depression.
In addition to the special light bulbs and glasses, there are apps you can download on your smartphones or mobile device. Many phones now come with built-in blue blocker settings.
Doctors say there’s evidence that reducing blue wave lengths can help you fall asleep.
Unfortunately, not all the research is positive. One study shows there’s not enough evidence to claim blue blocking glasses work.
