A cardiologist has raised concerns about the impact of extreme summer heat on cardiovascular health, highlighting how rising temperatures can overwork the heart and lead to serious health risks.
Dr. Adedapo Iluyomade, a cardiologist at Miami Cardiac & Vascular Institute, explains that as the body’s temperature rises, blood vessels near the skin expand, increasing the heart’s workload to maintain blood pressure. This added strain can lead to symptoms such as increased heart rates, dehydration, and even cardiovascular events.
The cardiologist cites studies showing that even slight temperature increases can elevate heart rates by nearly 30 beats per minute, with each 1°C rise increasing the risk of cardiovascular death by approximately 2%. For individuals with pre-existing conditions such as coronary artery disease or high blood pressure, the risks are even more pronounced.
Dr. Iluyomade advises taking precautions like avoiding peak heat hours, staying hydrated, and recognizing early warning signs such as chest tightness or dizziness to prevent cardiac incidents. He also notes that some heart medications can exacerbate the body’s response to heat, underscoring the need for careful management of existing medical conditions during hot weather.
Experts recommend staying in cool, shaded areas, wearing light, breathable clothing, and taking regular breaks from the sun to reduce the risk of heat-related cardiac stress. Additionally, the American Heart Association highlights the importance of monitoring for signs of heat stroke, including high body temperature and hot, dry skin.
As extreme heat becomes more frequent, especially in regions experiencing prolonged heatwaves, public health officials and medical professionals are urging individuals to remain vigilant about the symptoms of heat-induced cardiovascular strain. The cardiologist concludes that by following simple but effective measures, the risks associated with summer heat can be significantly mitigated.
