LIGHT MOVES Circadian rhythms, dictated by the body’s internal clock, are influenced by exposure to light. “Because of this, the lights in your home can directly affect your health and wellbeing,” says certified lighting consultant Jennifer Taxson of Illuminations in DC. “Blue light suppresses melatonin, the sleep hormone, so being exposed to blue light at nighttime can prevent you from getting sleepy. Meanwhile, warm, red-toned light closer to bedtime can help encourage melatonin production.” Bridge, an app from Philips Hue, connects any light fixture with bulbs that mimic natural light patterns. The smart lighting system helps users wind down by dimming lights at day’s end. philips-hue.com; illuminc.com
