Light exposure during sleep may affect heart health

A recent study published in the "European Heart Journal" indicates that exposure to higher levels of light during nighttime sleep can lead to harmful changes in the structure and function of the heart. The study involved more than 11,000 individuals and found that those exposed to more than 3 lux of nighttime light were 2.4% more likely to experience an increase in left ventricular size, 1.5% more likely to have thickening of the heart wall, and 1.9% more likely to have a reduced cardiac contraction ability. These changes, known as cardiac remodeling, may be associated with an increased risk of cardiovascular diseases, including decreased cardiac efficiency and the potential development of heart failure. The research explains that light at night disrupts the body's biological clock, activates the sympathetic nervous system, and leads to heart disturbances. It also points out that maintaining complete darkness during sleep can reduce these risks.
