Night Light Linked to Heart Damage | Science News

New research reveals that sleeping with too much nighttime light may be silently damaging your heart—new data from over 11,000 people shows exposure to even modest light levels can cause structural changes like thickened heart walls and reduced pumping efficiency, signaling chronic stress on the organ. Scientists tracked participants for seven days using light sensors, then scanned their hearts via MRI three years later, finding those exposed to more than three lux of light had stiffer, less flexible hearts. This isn’t just about sleep—it’s a potential new risk factor for heart disease, with experts urging doctors to ask about bedroom lighting and suggesting darkness may be as vital to heart health as blood pressure or clean air.
