How Hydration Affects Joint Lubrication and Mobility
How Hydration Affects Joint Lubrication and Mobility. Introduction Our joints work like hinges, allowing us to move freely, bend, and stretch. For smooth movement, the joints rely on a substance called synovial fluid , which acts as a natural lubricant. Just like a machine needs oil to prevent friction, our joints need proper hydration to stay flexible and pain-free. Unfortunately, many people underestimate how much water intake affects joint health. Why Hydration Matters for Joints Synovial Fluid Production Synovial fluid is made mostly of water. When the body is well-hydrated, this fluid can cushion and protect the joints, preventing bones from rubbing against each other. Without enough water, synovial fluid becomes less effective, leading to stiffness and discomfort. Cartilage Health Cartilage is the tough, rubbery tissue that covers the ends of bones. It’s made up of about 70–80% water . Dehydration can cause cartilage to dry out, reducing its ability to absorb sh...
