Adding Lemon to Your Water Improves More Than the Taste

Lemon juice contains potassium, an electrolyte known to be an important player in hydration. When you're parched, Cohen and Bria recommend hydrating with water that's been amped up with a squeeze of lemon plus a pinch of sea salt (sodium helps your body hold on to the right amount of water). This also makes a great preworkout drink, says Cohen, though if it's hot outside or you plan to exercise for more than an hour, you may want the extra electrolytes found in sports beverages.
