I don't see why everyone is interested in blood sugar aide devices. I don't really give a crap about how much insulin my body produces, nor some BS about insulin resistance.
The comparison is strained because blood sugar devices are specifically marketed to diabetics. I see that most sleep aid devices are marketed to the general population -- the messaging isn't "are you having trouble sleeping?" it's "Do you want to be a more effective person? Track your sleep!"
Most people in the US today have chronic sleep deprivation. Just because most people are used to not being healthy doesn't mean it is normal (over the course of human history).
