Lucknow : Climate and public health experts have raised serious concerns over the potential impact of prolonged heatwaves in India, warning that a five-day extreme heat event could result in significant loss of life, particularly in highly populated states such as Uttar Pradesh.
According to expert assessments based on recent heatwave trends and demographic data, as many as 8,056 deaths could occur in Uttar Pradesh alone if severe heatwave conditions persist for five consecutive days. The projections are largely based on mortality patterns observed during the record-breaking heatwave episodes of 2024, when temperatures reached unprecedented levels across several parts of India and the world.
The concern is not limited to Uttar Pradesh. Experts estimate that a similar prolonged heatwave could potentially claim around 3,615 lives in Bihar, 2,964 in Madhya Pradesh, and 2,664 in Rajasthan. These estimates take into account factors such as population density, historical heat-related fatalities, and regional climate vulnerability.
Researchers further suggest that a nationwide extreme heat event of similar duration could lead to nearly 30,000 deaths across India. Uttar Pradesh remains a particular focus due to its status as India’s most populous state, where overall mortality figures are already among the highest in the country.
However, experts caution that these figures represent preliminary estimates and that the actual impact could be even greater. One key limitation is that much of the available data is derived from urban areas, while a substantial portion of Uttar Pradesh’s population resides in rural regions.
Rural communities, including farmers and daily wage workers, often spend long hours outdoors under intense sunlight and typically have limited access to cooling facilities or heat-protection measures. As a result, experts warn that the health risks associated with prolonged heatwaves may be significantly higher in rural areas than current projections suggest.
The findings underscore the growing urgency of climate adaptation and heat-resilience measures as extreme weather events become increasingly frequent.
