                                The popular "8 glasses a day" rule is a simplification, and in reality, fluid needs vary significantly among individuals, making the standard guideline not a one-size-fits-all solution. For most adults, when it comes to the question, "Is drinking 4 glasses of water enough?", the answer is a definitive no.
