Overview

• Daily fluid needs can surge to two to three liters as high temperatures add up to two extra liters lost through sweating and respiration
• Tap water, mineral water, herbal and fruit teas or diluted juice spritzers at room temperature or lightly chilled are the most effective ways to rehydrate
• Pure fruit juices and sweetened soft drinks aggravate thirst and dehydration and are linked to higher sugar intake that can contribute to chronic kidney disease
• Ice-cold drinks and sudden cold showers trigger thermoregulatory overdrive that increases sweating and can provoke rebound heat stress
• Health experts report that 50 to 90 percent of heat shock patients suffer acute kidney injury and warn that regular soft drink consumption elevates long-term kidney damage risk
