Humanizing Content Summary: Extreme heat has a profound impact on both the body and mind.
S extreme heat can significantly strain the cardiovascular system, raising blood pressure and increasing the demand for energy and oxygen. This is exacerbated by the hormone heart’s response to heat, which amplified the body’s need to circulate blood to the skin.(cardiovascular deaths rise because Congress report that each 1°C increase in heat temperature results in a 2% increase in death rates, with heatwaves particularly increasing the risk of heart attacks and heart failure.
Iluyomade Iluyomade, a cardiologist at MiamiCardiac & Vascular Institute with part of Baptist Health South Florida, emphasized the heat’s strain. She noted that heat exposure can lead to dehydration and blood-thickening, potentially causing cardiac issues. A recent study analyzed over 6,000 heat exposure cases, revealing that even small temperature increases can raise heart rates by nearly 30 beats per minute, raising oxygen demand.
The American Heart Association (AHA) also identifies heat as a potential trigger for silent heart attacks in individuals with pre-existing coronary artery disease. This underscores the need for individuals with heart conditions to take proactive steps, including avoiding extreme heat, staying hydrated, and maintaining hydtocracy (habit of staying in cool, shaded areas). Others to watch out for include frequent chest tightness, heart pounding, symptoms like dizziness, and vagueintent.
AHA guidelines also highlight additional symptoms of heatstroke, such as high body temperature and hot, red, dry or damp skin. preparatory actions include staying hydrated, taking single breaks during midday, avoiding strenuous physical exertion, and wearing lightweight, breathable clothing to aid heat management.
In conclusion, extreme heat demands careful handling to avoid cardiac hypertension, heart failure, and irregular rhythms. By monitoring symptoms, adhering to healthy lifestyle habits, and adopting these strategies, both individuals and communities can mitigate the harmful effects of heat. Always be mindful of hydration, proper environment choices, and staying fit.
