Amid intensifying heatwave conditions across several parts of India, doctors from AIIMS have warned citizens against relying solely on water intake during extreme heat exposure, emphasizing the urgent need to replenish electrolytes to prevent dehydration, heat exhaustion, and heatstroke.

Medical experts at AIIMS stated that excessive sweating during prolonged heat exposure causes the body to lose critical electrolytes such as sodium, potassium, and chloride, which are essential for maintaining muscle function, blood pressure, hydration balance, and neurological stability. Doctors cautioned that drinking only water in extreme conditions may dilute sodium levels further, increasing the risk of fatigue, dizziness, muscle cramps, nausea, and severe heat related illnesses.

The warning comes as several northern and central Indian states continue to record temperatures exceeding 45 degrees Celsius. According to the India Meteorological Department, multiple regions have witnessed persistent heatwave alerts this season, with urban heat stress significantly impacting vulnerable populations including children, elderly individuals, outdoor workers, and patients with chronic illnesses.

Healthcare professionals recommend oral rehydration solutions (ORS), electrolyte based drinks, coconut water, lemon water with salt, and balanced fluid intake during extreme heat conditions. Doctors also advised avoiding direct sun exposure between 12 PM and 4 PM, wearing light-colored clothing, and increasing fluid consumption even in the absence of thirst.

According to the National Centre for Disease Control (NCDC), India recorded over 40,000 suspected heatstroke cases and more than 100 heat related deaths during severe summer conditions last year. Public health experts warn that rising temperatures linked to climate variability are increasing the frequency and intensity of heat related medical emergencies nationwide.

AIIMS specialists further highlighted that dehydration can worsen cardiovascular diseases, kidney disorders, diabetes complications, and neurological conditions. Hospitals in several cities have already reported increased cases of heat exhaustion, fainting, electrolyte imbalance, and dehydration related admissions over recent weeks.

India remains among the countries most vulnerable to extreme heat events, with studies estimating that heatwaves could impact productivity, healthcare infrastructure, and public health outcomes significantly over the coming decade. Health authorities continue to urge citizens to prioritize hydration, electrolyte balance, and preventive care measures as summer temperatures continue to rise across the country.
