Sleeping with light on causes weight gain

“Too much light at night appears to lead to weight gain, according to a report, based on studies of mice that provide fresh clues on obesity.

The researchers found that mice exposed to a dim light at night over eight weeks had a weight gain that was about 50 per cent 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 the others," said Laura Fonken, lead author of the study and a researcher at Ohio State University.
