Can Blue Light Alter Your Metabolism and Affect Your Weight?

According to a recent Northwestern University study, it can. During their research into the effects of artificial blue light on humans, metabolism, insulin levels, and glucose levels were shown to be negatively affected. Their study, which was published last week, showed that blue light manipulates metabolic regulation, and can lead to weight gain and potentially increase risk of diabetes. These are not good outcomes. The N.U. study was led by graduate student, Ivy Cheung, and included 19 adults who were subjected to varying levels of artificial light during the morning and evening, while blood levels were measured at regular intervals. In the end, researchers showed that while natural blue light in the morning can have a positive effect on metabolic regulation, in the evening, both natural and especially artificial blue light can have a negative effect on metabolism, insulin resistance, and glucose levels. The study has since been featured on various websites such as Science World Report and Tech Times.


As more and more information is exposed through scientific research, it’s increasingly clear that protecting your eyes and yourself has never been more important. Many of us are anchored to a digital device throughout the day and on into the evening, so having a pair of GUNNARS to help shield you from harmful blue light is a must. In fact, with our two new styles, Cypher and Trooper, now on, the choices available are even better. Now’s the time to end the pain of eyestrain, and apparently, weight gain.
