New research suggests nighttime light exposure may affect heart structure. A study observed thicker heart muscle and reduced flexibility in participants. This research adds to growing evidence on light pollution's health effects. Scientists tracked light exposure and conducted cardiac imaging on over eleven thousand people. Reducing bedroom light could potentially support cardiovascular health.

Even a small amount of light exposure during sleep may change the shape and function of heart muscles, increasing the risk of future heart disease, a new study found.

La investigación analizó a 11.000 personas y detectó alteraciones cardíacas asociadas a la exposición nocturna a iluminación, incluso en niveles bajos
