Summer heat spikes heatstroke, heart attacks and legionella cases across regions

Rising summer temperatures are leading to a surge in heat‑related illnesses. In Düzce, Dr. Yasin Haydar Yartaşı warned that heatstroke cases have risen, especially among the elderly, pregnant women, children and those with chronic conditions, and urged immediate emergency‑room visits if confusion or loss of consciousness occurs. Cardiologists across several countries, including Prof. Dr. Mehmet Ballı and Dr. Özgür Mete, reported that temperatures above 30 °C increase heart‑attack risk because the heart must work harder and blood vessels dilate, causing fluid and electrolyte loss. They recommend drinking 2–2.5 L of water daily, avoiding heavy meals, limiting strenuous activity and allowing gradual temperature changes to prevent rhythm disturbances. Pulmonologists such as Prof. Dr. Şevket Özkaya highlighted a parallel rise in legionella pneumonia linked to poorly maintained air‑conditioning systems and an uptick in food‑ and water‑borne diarrheal illness. They stress regular AC filter cleaning and strict food‑safety practices, including thorough washing of leafy greens. Across the affected regions, health experts advise staying in shade between 11:00 a.m. and 4:00 p.m., wearing light clothing, staying well‑hydrated, monitoring symptoms and seeking prompt medical care for severe dehydration, chest pain, or neurological signs.
