The fountain of youth is really a water fountain.

(Washington, DC) — A new study suggests that adults who aren’t sufficiently hydrated age faster. The study, conducted by the National Institutes of Health, looked at eleven-thousand Americans over a period of 25 years. It found that those who weren’t drinking enough fluids, as determined by the amount of sodium in their blood, were at higher risk for age-related conditions such as heart failure, kidney disease, dementia, diabetes, stroke and even premature death. The study’s authors believe that consistent good hydration could slow the aging process.
