We all know that water is essential for the body, which is made up of about 60% of it. But recent studies have sparked an interesting debate: could milk actually be healthier and more hydrating than water?
Hydration isn’t just about satisfying your thirst; it’s about keeping your body’s systems running smoothly. Your brain, muscles, digestion, and even mood depend on it. So, when it comes to wellness and hydration, should you reach for a glass of milk or stick with water? Let’s find out what the science and health experts say.
