Mumbai, Jun 3: Health experts have cautioned that drinking water alone may not be sufficient to stay properly hydrated during heat waves, as excessive sweating leads to the loss of essential electrolytes such as sodium, potassium, calcium, and magnesium.
Doctors said the loss of both fluids and minerals during extreme heat can lead to symptoms including dizziness, headache, muscle cramps, fatigue, and low energy levels. They stressed that electrolytes play a key role in muscle and nerve function as well as fluid balance in the body.
Dr Divya Gopal of Sir H N Reliance Foundation Hospital said consuming only water after heavy sweating can dilute electrolytes in the body, leading to fatigue, cramps, dizziness and persistent thirst. She recommended replenishing electrolytes through ORS, coconut water, lemon water with salt, buttermilk, and balanced meals.
Saifee Hospital’s Dr Murtaza S Bagwala said dehydration can become severe during extreme heat, affecting vital organs and potentially causing low blood pressure, rapid heartbeat, and even fainting. He added that elderly people, children, and those with chronic illnesses are at higher risk of complications.
He also warned that severe dehydration can lead to heat exhaustion, heat stroke, confusion, and irregular heart rhythms due to electrolyte imbalance.
L H Hiranandani Hospital’s Dr Vimal Pahuja noted that patients with diabetes, hypertension, and heart disease are especially vulnerable, as dehydration can worsen their conditions. He added that reduced blood volume may lead to dizziness, fainting, kidney injury, and serious metabolic complications in some diabetic patients.
Doctors urged people to take preventive measures during extreme summer conditions to avoid life-threatening complications.
