Electrolyte Drinks vs Plain Water (Everyday)

Quick answerFor everyday hydration and exercise under 60-90 minutes, plain water is optimal — electrolyte drinks add unnecessary calories and cost. For prolonged exercise (over 60-90 minutes), hot conditions or heavy sweating, electrolyte drinks help replace sodium and prevent hyponatraemia. The everyday marketing of electrolyte drinks for general hydration is largely unnecessary — a balanced diet provides ample electrolytes. Save electrolyte supplementation for genuinely demanding endurance or heat scenarios.

Factor	Electrolyte Drinks	Plain Water (Everyday)
Everyday hydration	Unnecessary	Optimal
Exercise under 60 min	Unnecessary	Sufficient
Exercise over 90 min	Beneficial	May need supplementing
Hot conditions	Beneficial	May need supplementing
Cost	Higher	Minimal

Choose Electrolyte Drinks when…

You're doing prolonged exercise over 60-90 minutes, training or competing in heat, sweating heavily, or recovering from illness with fluid loss.

Choose Plain Water (Everyday) when…

You're hydrating day-to-day, exercising under an hour, eating a balanced diet (ample electrolytes), or want to avoid unnecessary calories and cost.

FAQ

Do I need electrolyte drinks every day?

For most people, no — a balanced diet provides ample electrolytes, and plain water is optimal for everyday hydration and exercise under an hour. Electrolyte drinks are genuinely useful for prolonged endurance exercise (90+ minutes), heavy sweating or hot conditions, not routine daily hydration.

What electrolytes do you lose when sweating?

Sweat contains primarily sodium (the highest concentration), with smaller amounts of chloride, potassium, calcium, and magnesium. Sodium is the electrolyte most critical to replace during prolonged exercise — it maintains blood volume and drives thirst. Potassium, magnesium, and calcium are lost in smaller amounts and are usually replenished adequately through normal food for all but the most extreme exercise.

When are electrolyte drinks genuinely useful?

Electrolyte drinks are genuinely useful when: exercising for more than 60–90 minutes (especially in heat), when sweat rates are high (visible heavy sweating), during multi-day events where recovery between sessions is important, and for athletes who notice salt deposits on skin or kit (indicating high sodium losers). For everyday activity, normal food provides sufficient electrolytes and adding drinks is unnecessary.
