Even dim light can disrupt sleep, raising the risk of serious health issues in older adults, a new study found.
"Exposure to any amount of light during the sleep period was correlated with the higher prevalence of diabetes, obesity and hypertension in both older men and women," senior author Phyllis Zee, chief of sleep medicine at Northwestern University Feinberg School of Medicine in Chicago, told CNN.
