When chronically dehydrated, all of the body’s organs begin to weaken prematurely. The skin, the largest organ, gets dry, rough and itchy, when dehydrated, making it very prone to wrinkles. Healthy skin usually has about 20 percent water. Dehydrated skin can drop to under 10. The skin then doesn’t retain moisture and the flow of nutrients is affected. If you don’t fix this problem and your body cells don’t get what they need to function properly, they will get damaged.
