Research shows blue lights suppress melatonin, a chemical that makes us sleepy. So, I strategically use blue light throughout my home office in the morning and early afternoon to stay alert. I like LIFX smart lights because their bulbs are full-spectrum—offering brighter levels of daylight blue up to 9,000 Kelvin (K), whereas Philips Hue lights only go up to 6500K. In the later afternoon, I wind down with warmer tones (2500- 3500K) so that exposure to blue light doesn’t affect my sleep. Pair smart light bulbs with a voice assistant (#Hack 13), and you’ll be a few words away from a high- voltage, energized day.
