- Transporting Nutrients and Oxygen: Water carries essential nutrients and oxygen to cells while removing waste products.
- Supporting Digestion: It aids in breaking down food and absorbing nutrients efficiently.
- Lubricating Joints and Tissues: Water keeps joints, eyes, mouth, and other tissues moist.
- Detoxification: It assists kidney function in filtering out toxins and waste products.
- Maintaining pH Balance: Proper hydration helps regulate the body's acid-base balance.
