Nighttime light exposure: The hidden metabolic threat that rivals genetics in driving diabetes risk
A 2026 meta-analysis of 867,647 participants found high nighttime artificial light exposure increases obesity risk by 14% and overweight risk by 7%
A Lancet study tracking 84,790 people over 670,000 person-years found bright nighttime light exposure independently predicted Type 2 diabetes risk, comparable to moderate genetic predisposition
Even a single night of moderate light during sleep increases next-day insulin resistance and raises heart rate, according to Northwestern Medicine research

Experts recommend blackout curtains, removing electronic devices from bedrooms, and using dim amber lights as protective measures
