This little red-light device has transformed our wind-down ritual. How it works: Simply press the “on” button as you’re getting ready for bed, and Helight Sleep will start diffusing 630 nanometer pure red light. (It makes your whole room glow red, which counters the effects of blue light exposure.) And that’s the start of the simplest sleep protocol—the device emits a pure 630 nanometer red wavelength for 14 minutes and will gradually fade out until the end of its 28-minute cycle.
