Does your night ever go like this: You finish your dinner, put the kids to bed, take care of a few chores only to realize you are past your bedtime. So you brush your teeth, etc. and crawl into bed, pick-up your cell phone and take care of a few last minute emails or check a few Facebook posts. An hour or more later, you are way past your bedtime, and have been subjected to an hour of cell phone blue light that is going to destroy your ability to fall asleep. Well you are in luck, there is an App for that.


In resent research, the blue light from our phones, tablets, laptops, TV’s and other devices disrupts your natural circadian rhythm which increases your ability to fall asleep and stay asleep as part of our healthy sleep-wake cycles. Why, “The cause is the photoreceptor in your eyes, called Melanopsin. This receptor is sensitive to a narrow band of blue light in the 460-480nm range which may suppress Melatonin production – a hormone responsible for your healthy sleep-wake cycles.” -Twilight Website
