Researchers tracking 88,905 people for 9.5 years discovered those sleeping in the brightest bedrooms faced a 42% higher heart attack risk compared to those in darkness. The study used wrist sensors to measure light exposure for one week, collecting 13 million hours of data. Participants with moderately bright rooms showed 20% higher heart attack risk, while the brightest environments increased risk by 47%. Even after accounting for diet, exercise, smoking, and genetics, the 42% increased risk remained. The research also found elevated risks for heart failure, coronary artery disease, irregular heartbeat, and stroke. Women appeared more vulnerable than men to nighttime light’s heart-damaging effects. The average participant age was 62, with 57% being women. Simple solutions include blackout curtains, turning off devices, and keeping bedrooms dark to protect cardiovascular health. (Story URL)
