27 Dec 2025

Description

Almost all kids are afraid of the dark, and sometimes that fear even lingers into adulthood. It's a shame really because, contrary to what you might think, darkness is actually not our enemy but a friend when it comes to drifting off to dreamland. Being exposed to light at night can have negative consequences on person’s health in the long-term. That’s according to a study by researchers at Northwestern University's Feinberg School of Medicine in the United States. They published their findings in 2022, having discovered a correlation between exposure to light while sleeping and conditions like obesity, high blood pressure and diabetes. What's the link between light and disease? How can I ensure I’m not at risk from light exposure at night? In under 3 minutes, we answer your questions!
