Hue got it! You've heard that late-night exposure to blue light, like the glow from your tech devices, can wreck your sleep. (Shed a tear for all those hours spent scrolling through Instagram under the covers.) But on the flip side, red light may help you catch your z's more easily, according to sleep psychologist Michael Breus, PhD, author of the new book The Power of When ($28, amazon.com).

Even better news: A bordello vibe isn't necessary to reap the health benefits. You can buy red spectrum bulbs, which minimize blue light wavelengths and maximize red ones without reading as rosy-colored (it’s the spectrum of the light that makes a difference, not the physical color).
