Heat warning: Heart attack risk rises above 30 degrees Celsius

Cardiologists are warning of an increased risk of heart attacks as temperatures climb above 30 degrees Celsius (86 degrees Fahrenheit). Prof. Dr. Mehmet Ballı, Chief Physician and Cardiology Specialist at Mersin City Training and Research Hospital, noted a rise in heart attack cases during periods of extreme heat.

Ballı explained that high temperatures place a greater workload on the heart. As blood vessels dilate to help the body regulate its temperature, the heart must pump more blood, leading to increased strain. This physiological response makes individuals, particularly those with pre-existing cardiovascular conditions, more vulnerable.

To mitigate these risks, Ballı emphasized the importance of hydration, recommending at least 2.5 liters of fluid daily for patients, unless medically restricted. He suggested consuming fluids like ayran and soda, which can help replenish electrolytes, while cautioning against relying on sugary drinks, sodas, coffee, and tea for hydration. Water should be the primary beverage.

Furthermore, Ballı advised avoiding strenuous exercise and direct sun exposure during the hottest parts of the day. He also cautioned against sudden transitions between very hot and cold environments, such as entering a heavily air-conditioned room immediately after being in extreme heat or diving into cold water while overheated. Such abrupt changes can trigger heart rhythm disturbances. He recommended gradually adjusting to different temperatures, including setting air conditioners to comfortable, adaptable levels rather than extremely low settings.
