Light or no light? How your exposure at night may impact cardiovascular health

New research indicates that sleeping in brightly lit conditions significantly increases the risk of cardiovascular disease, including heart failure, coronary artery disease, and stroke. This disruption of the body’s circadian rhythm, by suppressing melatonin production, negatively impacts heart health. Conversely, high daytime light exposure is linked to better cardiovascular outcomes, emphasizing the importance of natural light cycles.
