Let the sunshine in for better health

A study from Northwestern Medicine and the University of Illinois at Urbana-Champaign indicates that all-day exposure to natural light, even by means of a window, leads to longer sleep duration at night, as well as increased physical activity and quality of life.

“There is increasing evidence that exposure to light, during the day, particularly in the morning, is beneficial to your health via its effects on mood, alertness and metabolism,” says senior study author Dr Phyllis Zee, a Northwestern Medicine neurologist and sleep specialist.
