Sleep Light Threatens Heart Health: Study Reveals Risks
A recent study reveals that even minimal light exposure during sleep can disrupt heart health. Participants exposed to illumination above three lux experienced noticeable changes in heart muscle shape and function.
Study Details
The experiment monitored volunteers' bedroom lighting levels over several weeks. When light exceeded three lux, medical devices recorded alterations in cardiac wall thickness and electrical activity.
Researchers warn that such changes may increase long‑term heart disease risk and recommend minimizing nighttime lighting.
Scientific Background
Nighttime light interferes with the body's circadian rhythm, suppressing melatonin and affecting cardiac recovery. The findings highlight the need to adopt dark‑room sleeping habits for better heart health.
Public awareness about the benefits of complete darkness during sleep is essential to reduce cardiovascular risks.
