(Robby Berman/ Medical News Today) — A study from Northwestern University Feinberg School of Medicine in Chicago explores the link between light exposures during sleep and health risks. The research serves as a warning for the many people living in industrialized nations where light tends to be omnipresent.
Sleeping while exposed to any type of light whatsoever — even dim light — is linked to an increase in the likelihood of obesity, diabetes, and hypertension (high blood pressure) in older adults, the study finds.
Corresponding author for the study, Dr. Minjee Kim, of Northwestern Medicine Feinberg School of Medicine, said in a press release: “Whether it be from one’s smartphone, leaving a TV on overnight, or light pollution in a big city, we live among an abundant number amount of artificial sources of light that are available 24 hours of a day.” (…)
