Extreme Heat Wave in Cordoba: Urban Heat Islands and Health Risks

Cordoba, Argentina, is experiencing an intense heat wave this week, with temperatures exceeding 35°C and reaching up to 40°C. This could be the hottest week of the summer, according to climatologists. The heat wave began on Monday with a high of 37°C and is expected to last until Friday. The extreme heat poses a significant health risk, particularly in urban areas known as "urban heat islands." These areas, characterized by dense concrete and lack of vegetation, can experience temperatures several degrees higher than surrounding areas. Cordoba, with its extensive urban sprawl, has one of the largest urban heat islands in Argentina, with temperatures potentially reaching 45°C even when the official forecast is 35°C. The heat wave has raised concerns about heatstroke, which can be difficult to diagnose in hospitals due to its similar symptoms to other illnesses. Early detection is crucial, and symptoms like headache, low blood pressure, altered mental state, and in severe cases, loss of consciousness, require immediate medical attention. Children and elderly individuals are particularly vulnerable, with symptoms including fever, nausea, dizziness, vomiting, and excessive sweating. To mitigate the impact of the heat wave, experts recommend staying hydrated, avoiding outdoor activities during peak hours, keeping indoor temperatures around 20°C, and consuming light meals rich in water content. The city's power company, Epec, has reported no major power outages due to increased demand, but they emphasize the importance of using air conditioners efficiently, setting them to 24°C and only cooling occupied rooms. They also encourage the use of fans, which consume significantly less energy than air conditioners. The heat wave highlights the urgent need for urban planning strategies that prioritize green spaces and sustainable building practices to reduce the impact of extreme heat on public health and energy consumption.
