Light Pollution, Circadian Disruption, Cardiac Vulnerability 🌃🕰️🫀

🌙 Bright Nights, Higher Heart Risk ❤️‍🩹   New findings in JAMA Network Open highlight that greater exposure to artificial light at night is associated with significantly increased risks of coronary artery disease, myocardial infarction, heart failure, atrial fibrillation, and stroke — independent of sleep duration, lifestyle factors, and genetics.   💡 Clinical takeaway: Protecting circadian rhythms is cardiovascular prevention. Darker nights = healthier hearts.   🛌 Simple steps: blackout curtains, limit screens before bed, use warm/dim evening lighting.   #Cardiology #JAMANetworkOpen #CircadianHealth #SleepMedicine #PrecisionPrevention #PublicHealth
