Heatwaves not only pose a direct risk to human health through heat-related illnesses but also exacerbate existing cardiovascular conditions. Here’s what to do.

Heatwave alerts have been issued for several states as the country braces for extended spell of extreme heat in the coming months. Scorching summer heat not only makes you sweat more, it also burdens our essential body functions, posing a significant risk of health complications due to heat exhaustion and dehydration. Heatwave can also affect the way our heart functions. In order to regulate our body temperature, our heart has to work extra hard to ensure blood flow. This can put a strain on the crucial organ and a lack of proper cardiovascular care can make one susceptible to events like heart attack.

While individuals with healthy cardiovascular systems may tolerate this stress, those with pre-existing heart conditions are at heightened risk, potentially leading to heart attacks.

Drinking sufficient fluids in hot weather conditions can help support normal body function. It is also crucial to avoid peak hour sunlight, wear cotton clothing and stay in air conditioning to mitigate effects of heatwave.

“As the world grapples with the increasing frequency of extreme weather events due to climate change, understanding the connection between heatwaves and heart attacks becomes paramount. Heatwaves not only pose a direct risk to human health through heat-related illnesses but also exacerbate existing conditions like cardiovascular diseases,” says Dr Abhijit Khadtare, Cardiologist at Ruby Hall Clinic, Pune.

“During a heatwave, the body’s thermoregulation mechanisms are put to the test. To cool itself down, the body relies on sweating and increased blood flow to the skin. This places a significant burden on the heart, which must pump harder and faster to facilitate this process. While individuals with healthy cardiovascular systems may tolerate this stress, those with pre-existing heart conditions are at heightened risk, potentially leading to heart attacks.”
