A recent statement from experts at Weill Cornell Medicine and the American Heart Association warns that extreme temperatures are increasingly threatening cardiovascular health. The report highlights that while cold weather historically caused more cardiovascular deaths, rising heat events are becoming more frequent and severe, potentially leading to a higher number of heat-related fatalities. Vulnerable groups such as older adults, pregnant individuals, and outdoor workers are at heightened risk. Dr. Arnab Ghosh, a lead author, emphasizes the need for coordinated action across research, clinical practice, and policy to protect public health. The healthcare sector, which contributes significantly to greenhouse gas emissions, must adapt its practices to mitigate climate impacts. Recommendations include more research on temperature thresholds for cardiovascular risks and improving access to cooling resources. Urban planning, such as planting trees to create shade, is also essential for reducing heat exposure in communities. The authors call for immediate action to address these challenges, stating that heat is a pressing problem that requires innovative solutions.
