If you’re not familiar with the effects of blue light, you might want to read about it. We’ve heard for the past few years that it’s a good idea to not watch TV or use any other electronic devices starting an hour before you plan to go to bed. That’s because many electronic devices emit blue light which limits the production of the hormone, melatonin, which is essential to sleep. Shutting off electronics, is more difficult for some than others. Night Shift is a feature that allows you to set a time (or turn it on and off manually) that your device will emit warmer lights and limit the use of blue light, theoretically allowing for more restful sleep.
