What you need to know about H3O2

Exercising regularly, eating a balanced diet, and sleeping well—all those components of a healthy, high-performance lifestyle may be undercut if you’re not properly hydrated, say Dana Cohen, MD, and Gina Bria, authors of the newly-released book Quench.

And chances are you’re not at optimal hydration levels: according to recent research cited in the book, up to 75 percent of Americans are dehydrated, a condition that can show up as fatigue, irritability, and lack of focus. Chronic, low-grade dehydration may also contribute to more serious conditions, from decreased immunity and joint pain to Alzheimer’s and heart disease. Moreover, a University of Arkansas study suggests that even very mild dehydration—a loss of as little as two percent of your body weight—can affect blood vessels in the same way that smoking a cigarette does.

On the upside, proper hydration can reap all sorts of benefits, including soaring energy levels, better cognitive function, improved sleep, more radiant and younger-looking skin, and more.

Instead of reaching for another glass of water, Cohen, an integrative physician with a Manhattan medical practice and Bria, an anthropologist with a background researching indigenous desert tribes and founder of the Hydration Foundation, argue that there’s a better way to hydrate. Here, the authors discuss their best tips based on the latest science on water, and the surprising role movement plays in hydration.
