Water is the most essential and commonly recommended hydration drink. It is a natural and calorie-free option that helps replenish fluids in the body. Other popular hydration drinks include sports drinks, coconut water, herbal tea, and infused water with fruits or herbs. Electrolyte or sports drinks are water-based beverages with carbohydrates (sugar) and essential minerals like sodium and potassium. They help replenish electrolytes lost through sweat during intense exercise and support hydration.
