The human body is, on average, 60 percent water. So it makes sense that water is doing something important in there. And indeed, water is necessary for almost all physiological processes.
In the past few years, research on hydration has shifted from studying the role of hydration in athletic performance to water’s role in overall health. And scientists are finding some interesting connections.
Water Is Essential to the Body
There is evidence that insufficient hydration can cause inflammation, stiffen arteries, and interfere with blood pressure control (causing blood pressure to swing wildly from too high to too low). According to a study published in 2022 in the European Heart Journal, staying well-hydrated during middle age can reduce the risk of heart problems later in life.
