Sleeping in Lit Room - 불켜진 방에서의 수면

  Too much light at night appears to lead to weight gain, according to a report. The researchers found that mice exposed to a dim light at night over eight weeks had a weight gain that was about 50% more than other mice that lived in a standard light-dark cycle. "Although there were no differences in activity levels or daily consumption of food, the mice that lived with light at night were getting fatter than others," says Laura Fonken, lead author of the study and a researcher at Ohio State University.

  The weight gain could be a sign that light has an effect on the metabolism. Something about light at night may have made mice want to eat at the wrong times to properly metabolize their food. If these results are confirmed in human, it would suggest that late-night eating might be a particular risk factor for obesity.

  The findings offer clues for caused of the obesity epidemic in Western countries. Societal obesity is correlated with a number of factors including the extent of light exposure at night. Prolonged computer use and television have previously been linked to obesity, but because they are associated with a lack of physical activity It may be that people who use the computer and watch the TV a lot at night may be eating at the wrong times, disrupting their metabolism.
