Is your nightly TV habit harming your heart? New study reveals the hidden dangers of sleep light

A new study suggests that sleeping with the TV on may negatively impact heart health. The research, published in the Journal of the American College of Cardiology, found that nighttime light exposure can disrupt sleep and alter heart structure. The study involved 40 healthy adults who were exposed to either dim light or regular room light at night for one week. Those exposed to dim light had improved sleep quality and better heart health markers compared to those in regular room light.
