Eating while exposed to blue light increases insulin resistence

Eating while exposed to blue light from LED lights, your tv or laptop: altered metabolic activity and increased insulin resistance.
"Nineteen healthy adults were randomized to three hours of blue-enriched light exposure starting either 0.5 hours after waking (morning group) or 10.5 hours after waking (evening group). Each person's results were compared to their dim light exposure results as a baseline. The morning group ate breakfast in the light, while the evening group ate dinner in the light.
The study showed that blue-enriched light exposure acutely altered metabolic function in both the morning and the evening compared to dim light."
