The study found a link between blue light 57 —blue light is 58 by smartphones and tables—and increased hunger. It found that exposure to the light increases hunger levels for several hours and even increases hunger levels 59 eating a meal. Results of the US study show that blue-enriched light exposure, compared with 60 light exposure, was 61 with an increase in hunger that began 15 minutes alter light onset and was still present almost two hours after the meal. Blue light exposure has also already been shown to decreased 62 in the evening, increasing the risk of insomnia. Study co-author Ivy Cheung, of Northwestern University in Chicago, said, "A single three-hour exposure to blue-enriched light in the evening 63 impacted hunger and glucose metabolism." "These results are important because they suggest that 64 environmental light exposure for humans may represent a novel 65 of influencing food intake patterns and metabolism." The study group 66 10 healthy adults with regular sleep and eating schedules who received 67 carbohydrate-rich meals. They completed a four-day trial 68 dim light conditions, which involved exposure to less than 20 lux during 16 hours 69 and less than three lux during eight hours of sleep. On day three they were exposed to three hours of 260 lux, blue-enriched light starting 10.5 hours after waking up, and the effects were compared with dim light exposure on day two. Ms Cheung said more research is needed to determine the 70 of action involved in the relationship between light exposure, hunger and metabolism.
