Specifically, cardiovascular diseases are significantly affected by environmental stressors such as extreme temperatures and natural disasters according to Alimente.

Elderly individuals and marginalized groups are particularly vulnerable, as evidenced by past events like Hurricane Katrina's devastating impact on New Orleans.

Physiological Impacts of Environmental Stressors

The physiological effects are profound: exposure to extreme heat can elevate heart rates, thicken blood plasma, and exacerbate cardiovascular conditions.

Additionally, inhaling particulate matter from air pollution during heatwaves can cause pulmonary inflammation. Beyond direct physical impacts, the mental stress induced by climate-related disasters can further strain cardiovascular health, compounding the risks for vulnerable populations.

Scientific Evidence and Future Challenges

Scientific evidence underscores these concerns. Studies cited in the JAMA Cardiology journal show a clear association between prolonged exposure to extreme heat and increased cardiovascular mortality.

This includes findings from global studies linking heatwaves to higher risks of conditions like ischemic heart disease and stroke. As climate change continues to escalate global temperatures, the frequency and intensity of these extreme weather events are expected to rise, posing ever-greater risks to public health.

Understanding these connections is crucial as we prepare for the future impacts of climate change. Proactive measures to mitigate these risks, including better urban planning, improved healthcare infrastructure resilience, and public education on heat-related health precautions, will be essential in safeguarding cardiovascular health in a changing climate.
