Most of the water inside your cells isn't ordinary liquid water. Gerald Pollack, a bioengineering professor at the University of Washington, has spent two decades arguing it's something else entirely — and the implications, if he's right, reach further than biology.
When ordinary water touches a hydrophilic (water-loving) surface, the molecules at that interface reorganise into a structured, gel-like layer with different properties entirely. It's roughly 10% denser than bulk water, has a higher refractive index, and — critically — carries a net negative electrical charge.
Pollack holds the highest faculty honour at the University of Washington and is editor-in-chief of the peer-reviewed journal WATER. His 2024 paper demonstrating EZ water in tree xylem was published in Nature's Scientific Reports.
EZ water forms against every hydrophilic surface inside the body — cell membranes, proteins, collagen fibres, blood vessel walls, fascia, the inside of every cell. Because these surfaces are so densely packed, most of what fills a cell isn't ordinary liquid water at all.
Red blood cells carry a negative surface charge — their zeta potential — that keeps them repelling each other rather than clumping together. The electrical order in EZ water appears to be the mechanism maintaining that charge, with knock-on implications for microcirculation, fascia function, and mitochondrial energy production.
The earth's surface carries an abundant supply of free electrons. Biophysicist James Oschman's research suggests skin contact with the ground supports EZ water formation and maintenance — the same mechanism a tree draws on continuously through its roots.
Pollack's team found infrared light is the most powerful driver of EZ water formation — shine it on a water chamber and the exclusion zone can expand up to four times. The same mechanism drives photosynthesis in plants.
EZ water needs something to form against. Tree xylem — the vascular tissue that moves water against gravity up a 100-metre trunk — is one of the clearest natural examples of the same physics at work.
The fourth phase of water is a real, peer-reviewed observation from a credentialed research university. But the full mechanistic picture of how EZ water drives biological processes is still an active area of investigation, and some of Pollack's broader claims remain debated in mainstream cell biology. Treat this as fascinating emerging science — not settled consensus.
