Nightly Overexposure To Light May Lead To Obesity
A recent study reveals that too much light at can be a risk factor for weight gain.
A recent study published in the Proceedings of the National Academy of Sciences reveals that 0verexposure to light at night may increase the chances of weight gain, even with regular exercise and food intake.
Researchers Laura K. Fonken, Joanna L. Workman, et al, discovered that mice exposed to a relatively dim light at night over eight weeks had a body mass gain that was about 50 percent more than other mice that lived in a standard light-dark cycle.
From the abstract:
Low levels of light at night disrupt the timing of food intake and other metabolic signals, leading to excess weight gain. These data are relevant to the coincidence between increasing use of light at night and obesity in humans.
