Which guideline best describes hydration during exercise?

• A. Drink only when thirsty during exercise
• B. Sip fluids regularly to maintain hydration; general guidance is to resume fluid loss with water or electrolyte beverages as needed
• C. Avoid fluids entirely during exercise
• D. Hydration is not important for workouts under 60 minutes

Answer: (B)

Hydration during exercise means actively keeping up fluid intake to match what you lose in sweat. Because thirst doesn’t reliably signal you when you’re already dehydrated, the best approach is to sip fluids regularly to maintain your hydration level. Drinking water or an electrolyte beverage as you exercise helps maintain performance, regulate body temperature, and support recovery. Use water for most workouts, and add an electrolyte drink when sweat losses are high, you’re exercising longer, or you’re in hot conditions to replenish minerals like sodium. Don’t wait to feel thirsty, and don’t skip fluids entirely. Hydration matters for any workout duration, and keeping a steady intake helps prevent dehydration and its negative effects on performance.
