Technology’s glow is making it harder for us to sleep
The glow of the tech in our bedrooms cuts through the darkness and tricks our brain into thinking it's daytime, the Houston Chronicle's Jenny Deam writes on the front page:
- "Just by slapping on a pair of cheap orange sunglasses a few hours before bedtime while still using their regular devices, .. melatonin levels [for participants in a University of Houston study] shot up by 58 percent. Melatonin [tells your brain] it's time to sleep."
- "By simply shifting the visual hue from blue to orange (think sunset), the group reported drifting off earlier and more easily, plus staying asleep longer. Most added about a half-hour to their sleep total; one volunteer caught an extra hour and a half."
Why it matters: 1 in 3 of us report being sleep-deprived.
