Dr. Nieca Goldberg, a cardiologist from NYU Langone Health, warns that prolonged exposure to high summer temperatures can significantly strain the heart and circulatory system. When the body overheats, blood vessels dilate to release heat, which can lead to a drop in blood pressure and symptoms such as dizziness, confusion, and instability, especially when standing up quickly or spending extended time outdoors. During heatwaves, the heart works harder to cool the body, increasing pulse rate even during minor exertion. Dehydration caused by excessive sweating further reduces blood volume, making it harder for the heart to function properly. This risk is particularly elevated for individuals with heart conditions, low blood pressure, diabetes, kidney disease, obesity, or older adults. A 2024 study published in Circulation Research found that the risk of death from cardiovascular diseases increases by approximately 2.1% for every degree Celsius rise in temperature. To protect the heart during hot weather, Dr. Goldberg recommends avoiding outdoor activity during peak hours, staying hydrated, wearing light clothing, taking breaks in cool environments, and avoiding physical exertion when
