Exposure to artificial light at night while sleeping may be a risk factor for weight gain and the development of obesity, according to a study recently published in JAMA Internal Medicine. The study findings suggest that lowering artificial light exposure at night (ALAN) might be a useful intervention for obesity prevention.
A high-calorie intake and sedentary behaviors are generally considered to be the main contributors to the obesity epidemic and these are currently the most common targets in obesity prevention strategies. However, a growing body of evidence suggests that ALAN may also be a contributor.
