Infants and elderly individuals are particularly vulnerable to heatwaves due to physiological factors. Infants have immature thermoregulatory systems, higher metabolic rates, and reduced sweating capacity, making them prone to rapid overheating and dehydration. Older adults face challenges such as diminished cardiovascular resilience, reduced sweating, and impaired thirst perception, which increase their risk of heat-related illnesses like heatstroke, myocardial infarction, and kidney injury. The lack of adequate healthcare infrastructure, especially in rural areas, further heightens the risks for these groups. Without immediate action, the health impacts of heatwaves are expected to worsen, leading to preventable morbidity and mortality.
