Studies have shown that Alkaline water may hyrdrate better than plain or purifed water. Thanks to recent research conducted at Colorado State University, we now know why. Studies have shown a class of proteins found in every cell in the body called aquaporins can regulate the flow of water into and out of cells.
Aquaporins have a hollow channel which allows water to pass through one molecule at a time. In the presence of acids or other toxins, aquaporins will close up, and block water from moving through the cells. The reason aquaporins close up is to prevent the escape of protons (positively charged particles) from the cell.
Acidic water has an excess of protons and electrons in it. Because alkaline water has excess of electrons, aquaporins allow it to pass quickly into the cells which enable the body to be quickly and better hydrated.
