Sports Drinks vs. Plain Water: When Each Makes Sense

Sports drinks contain carbohydrate (for energy) and electrolytes (mainly sodium) alongside water — features plain water doesn't have. That extra content is genuinely useful in specific situations and unnecessary added sugar and cost in others.

For sessions under about an hour at moderate intensity, plain water is typically enough to stay hydrated. For sessions over roughly an hour, especially in heat or at high intensity with heavy sweating, a sports drink's carbohydrate and sodium content can help sustain energy and fluid balance more effectively than water alone.

Outside of exercise, sports drinks generally aren't needed — they're formulated for the specific demands of prolonged sweating and exertion, not everyday hydration, where they mostly just add sugar and calories without a real functional benefit.
