Abstract

This study examines the economic and health impacts of climate change on Tamil Nadu, India, with a focus on healthcare
workers' awareness, digital health readiness, and policy interventions. Rising temperatures, irregular rainfall, and extreme
weather events have led to an increase in climate-sensitive diseases such as dengue, chikungunya, waterborne illnesses, and
heat-related conditions. These health risks impose significant economic burdens through increased treatment costs, productivity
losses, and household financial strain, especially among vulnerable populations. Despite growing awareness among healthcare
professionals, gaps in training, infrastructure, and systemic support hinder effective response to climate-induced health crises.
Digital health tools, including telemedicine, disease surveillance, and geographic information systems, offer promising solutions
for early detection, cost reduction, and improved healthcare delivery, particularly in remote areas. However, economic barriers
such as limited internet access, device affordability, and digital literacy restrict widespread adoption. The study employs
secondary data analysis and statistical methods, including ANOVA, to assess the effectiveness of digital interventions and
policy measures. Findings reveal that strategic investments in digital health training and innovative financing can significantly
enhance climate resilience while offering cost-effective benefits. Policy recommendations emphasize strengthening digital
infrastructure, integrating climate-health considerations into planning, and ensuring equitable access for vulnerable groups.
Overall, leveraging digital health technologies and targeted policy support can mitigate climate-related health risks and foster a
resilient, sustainable healthcare system in Tamil Nadu. The research explores critical and fast-emerging issues that are
assuming greater relevance in today’s dynamic global landscape.
