"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," study senior author Dr. Phyllis Zee, professor of neurology at Northwestern University Feinberg School of Medicine and director of the Sleep Disorders Center at Northwestern Memorial Hospital, said in a university news release.
