Hyderabad Soaring Heat Triggers Rising Dehydration Risks
As Hyderabad braces for an intense summer, healthcare experts are raising alarms over the growing risk of dehydration among residents. The city’s semi-arid climate, coupled with rising temperatures, creates a conducive environment for silent and diarrheal dehydration, both of which often go unnoticed until severe complications arise. Dehydration is not just a matter of thirst—it can silently impair cognitive function, damage kidney health, and lead to life-threatening outcomes if left unaddressed. Vulnerable groups such as children, the elderly, and those with chronic conditions like diabetes are at higher risk. Data from health authorities indicate a significant spike in dehydration-related hospital admissions every summer, underscoring the urgent need for proactive hydration strategies. With water scarcity also an emerging concern in some parts of the city, experts stress the importance of public awareness regarding proper fluid intake and the use of scientifically backed rehydration solutions.
Silent dehydration, a particularly insidious form of fluid loss, occurs when the body loses essential electrolytes without triggering the usual thirst response. “This is particularly dangerous for diabetic individuals, who already experience altered fluid balance due to high blood sugar levels,” warns Dr B. Ravinder Reddy, Senior Consultant at Care Hospital, Hyderabad. Studies suggest that even mild dehydration can impair brain function, increase fatigue, and elevate stress levels. Factors such as strenuous activity, high temperatures, alcohol consumption, and fever further elevate the risk. Unlike plain water, electrolyte-based solutions are crucial in restoring the body’s balance, as they replenish essential minerals like sodium, potassium, and magnesium. Experts advise individuals, especially those with diabetes, to opt for low-sugar, electrolyte-rich hydration to maintain fluid balance and overall health.
Diarrheal dehydration remains another major public health concern, particularly among young children in Hyderabad. According to Dr C. Suresh Kumar, Professor of Paediatrics at RVM Medical College, infections and gastrointestinal disorders often cause rapid fluid loss, leading to severe complications such as shock and organ failure if untreated. Data from the National Family Health Survey (NFHS) reveals that diarrhoea accounts for a substantial number of paediatric hospitalisations during the summer months. The WHO-recommended Oral Rehydration Salts (ORS) remain the gold standard for managing such cases, ensuring rapid fluid absorption and electrolyte replenishment. However, incorrect mixing of powdered ORS solutions has been reported as a common issue, reducing its effectiveness. To counteract this, ready-to-drink ORS formulations are recommended, especially in households unfamiliar with precise preparation techniques. Public awareness campaigns focusing on early intervention, continued feeding, and zinc supplementation can significantly reduce dehydration-related paediatric mortality rates.
From a sustainability perspective, Hyderabad’s water crisis further exacerbates the dehydration risk. Reports indicate that several localities in the city experience periodic water shortages during peak summer, limiting residents’ access to clean drinking water. As climate change intensifies heatwaves and strains water resources, civic bodies must prioritise sustainable water management initiatives. Rainwater harvesting, efficient water distribution, and awareness campaigns on responsible consumption can mitigate the impact of heat-related dehydration. Additionally, urban planning must incorporate more green spaces and shaded public areas to reduce heat stress, making the city more resilient to extreme temperatures. By integrating hydration awareness with sustainable urban policies, Hyderabad can safeguard public health while promoting long-term water security.
