LEDs Mimic Sunlight to Help You Sleep Better

The circadian rhythm of the human body is tied to changes in sunlight. As it gets dark, for example, melatonin tends to make us sleepy. But artificial light can wreak havoc with that cycle. Ss you lie in bed clutching your iPad, the device's blue light might actually be telling your body to wake up and stay active. Enter Silk by Saffron, a smart LED lighting system that changes color temperature throughout the day to correspond with the sun. Silk bulbs are a wirelessly connected system that shift from midday's cool blue intensity to the warmer tones of evening.
