In this episode, I show you how you can determine whether your genetics are contributing to your sensitivity to blue light, poor sleep, and poor daytime alertness, and what you can do about it. Specifically, I look at the research showing that variations in the gene for the vitamin A-dependent protein melanopsin underlie sensitivity to blue light and I teach you how to figure out your own genetics for this protein using a 23andMe account (they don’t have a health report for it, but the hack around that is easy).
