Storing water in a copper bottle for 6 to 8 hours allows beneficial copper ions to infuse into the water, offering health benefits like improved digestion, immunity, and skin health. Leaving it overnight is ideal, while storing for up to 12–24 hours is safe, but avoid longer durations to prevent excess copper intake. Use clean water, avoid acidic liquids, clean the bottle regularly, and drink at room temperature. Consistent daily use ensures the best results from this natural, ancient wellness practice.
