Stay hydrated during long walks by drinking water before, during, and after your walk. Carry a reusable water bottle and sip small amounts every 15–20 minutes. Avoid sugary or caffeinated drinks that can cause dehydration. In hot weather, include electrolyte-rich fluids like coconut water or sports drinks. Eat water-rich fruits such as watermelon or oranges to maintain hydration and energy levels throughout your journey.
