Extreme heat events disproportionately affect vulnerable groups, including older adults, individuals with pre-existing health conditions, and those in socioeconomically disadvantaged areas. Urban heat islands, poor housing materials, and lack of access to cooling exacerbate exposure risks. Heatwaves can lead to acute health emergencies such as heatstroke, which has a high fatality rate, and worsen chronic conditions like cardiovascular and respiratory diseases. Additionally, heat-related disruptions to infrastructure can compromise healthcare delivery, increase accident risks, and reduce productivity. The cascading effects of heatwaves highlight the urgent need for preparedness and mitigation strategies.
