Water helps reduce inflammation by helping to maintain fluid balance. Because when there is not enough water in the bloodstream, there will be an imbalance in the ratio of molecules to total volume.
Research shows that when cells are exposed to higher-than-normal concentrations — such as when dehydrated — they cause inflammation.
Staying hydrated also helps reduce inflammation through its effect on cartilage and synovial fluid. When your joints move smoothly, they reduce friction.
Friction increases inflammation, so it is important to maintain smooth joint movement.
The general recommendation is to drink about six to eight glasses of water per day. The amount you need is affected by the weather, activity level, medications, and diet.
