Heatwaves pose significant risks to public health, productivity, and infrastructure. Vulnerable groups, including street vendors, daily wage workers, and rural populations, are particularly at risk of heat-related illnesses. Prolonged exposure to extreme heat can lead to dehydration, heatstroke, and even fatalities. Additionally, the economic impact is substantial, affecting agricultural yields, supply chains, and tourism. India's proactive measures, such as community-based support systems and urban planning for thermal comfort, aim to mitigate these risks and enhance resilience against rising temperatures.
