Episode Description from the Publisher

In today's episode we're exploring how light exposure at night can physically reshape your heart.Grounded in recent cardiovascular magnetic resonance (CMR) research from over 11,000 UK Biobank participants, we examine how nighttime light above 3 lux leads to left ventricular concentric hypertrophy, chamber dilatation, and reduced myocardial contraction.We discuss how reduced sleep duration mediates up to 49% of these structural changes. Furthermore, we break down the clinical risks associated with brighter nights, including significant increases in heart failure, stroke, atrial fibrillation, myocardial infarction, and cardiovascular mortality over nearly a decade of follow-up.=== REFERENCES ===https://doi.org/10.1093/eurheartj/ehag563https://www.ukbiobank.ac.uk/enable-your-research=== Support our work.
