In April 2026, heatwave conditions are affecting parts of Odisha, Chhattisgarh, and Jharkhand, with temperatures reported to be 3 degrees Celsius above normal. The India Meteorological Department (IMD) warns that dehydration is a significant health risk, often occurring before individuals feel thirsty. Dr. Aijaz Ilmi, a Senior Consultant in Preventive Health, emphasizes that dehydration can impair cognitive performance and stamina, with a 12% increase in cardiovascular mortality risk linked to even mild dehydration. Vulnerable populations, including those with diabetes, hypertension, and the elderly, face heightened risks as dehydration can lead to severe health complications. Experts recommend a structured approach to hydration, advocating for electrolyte-rich fluids like buttermilk and coconut water, monitoring urine color, and avoiding outdoor exposure during peak UV hours. As climate change intensifies heatwaves, proactive hydration is critical for maintaining health and preventing serious conditions.
