Extreme heat events pose significant risks to public health, particularly for vulnerable groups such as the elderly, children, and individuals with pre-existing conditions. Heatwaves can lead to acute mortality, hospitalizations, and disruptions in essential services like power and water supply. Urban areas, informal settlements, and outdoor workers are disproportionately affected due to exposure and lack of cooling infrastructure. Additionally, heatwaves can exacerbate air pollution, reduce labor productivity, and trigger public health emergencies. The cascading socioeconomic impacts highlight the urgent need for preparedness and mitigation strategies.
