New factor may impact heart health
A recent study has shown that exposure to high levels of light at night increases the risk of structural and functional changes in the heart, including thickening of the left ventricular wall and decreased heart muscle efficiency, after monitoring more than 11,000 people over three years. The link between nighttime light exposure and heart health is considered to be the first of its kind, and it is believed that light pollution could be a new factor threatening vascular health. The study advocates for reducing light exposure during sleep through simple measures such as using blackout curtains and warm lighting. The results highlight the need for further research to determine the extent to which reducing light can improve heart health.
