pH is just a scale that measures how acidic or alkaline something is, from 0 (battery acid) to 14 (drain cleaner). Pure water sits right in the middle at pH 7, which is neutral. Think of it as the Switzerland of liquids—it doesn’t pick sides.
But here’s the kicker: most drinking water isn’t perfectly neutral. Tap water usually falls between pH 6.5 and 8.5, and that’s completely fine. Your body is a master regulator; it doesn’t care if your water is a hair acidic or a hair alkaline—it balances itself out faster than you can say “electrolyte imbalance.” (Side comment: Your stomach acid is around pH 2. So, no, a glass of pH 8 water isn’t going to “alkalize” anything in there except maybe your expectations.)
