Sports drinks are designed to go beyond water by replenishing fluids, electrolytes, and energy lost during intense or prolonged exercise. They typically contain sodium, potassium, and carbohydrates to support hydration, prevent cramps, and sustain performance. While options like isotonic, hypotonic, and hypertonic drinks serve different purposes, choosing the right one depends on your workout intensity and duration. For light activity, water is enough, but for endurance or high-sweat sessions, sports drinks can improve recovery and energy. Understanding ingredients and sugar levels helps you make smarter hydration choices for better overall performance.
