                                While the famous “8x8 rule” of drinking eight 8-ounce glasses of water is a simple guideline, it is not a scientific recommendation and has been largely debunked. To accurately determine how many 16 oz glasses of water should you drink in a day, you need to consider multiple personal factors, moving beyond a one-size-fits-all approach.
