🌷 Spring Forward & Heart Health — Quick Summary for Patients Each March, when we “spring forward” for Daylight Saving Time, research shows a temporary increase in heart attacks and cardiovascular events in the days following the time change. The main reason? Sleep loss + circadian rhythm disruption + increased stress hormones can temporarily strain the heart — especially in people with high blood pressure, inflammation, chronic stress, or prior heart conditions. ❤️ Why It Happens Losing even one hour of sleep can: Increase blood pressure Raise cortisol and stress response Reduce heart rate variability Increase inflammation and vascular tension For vulnerable individuals, this can increase short-term cardiovascular risk.
