The claim that drinking 8 glasses of water a day is essential for hydration is oversimplified. The Institute of Medicine suggests that “men should aim for about 13 cups (104 ounces) of total beverages daily, while women should target around 9 cups (72 ounces)” from all sources, not just water (Healthline).
Furthermore, as Medical News Today explains, “the ‘8 glasses of water’ recommendation is a guideline and doesn’t account for individual needs,” such as activity level and climate (Medical News Today).
Moreover, Vogue notes, “Hydration depends on many factors… individual needs are different.” The myth of the 8 glasses is outdated and doesn’t reflect the true complexity of hydration (Vogue).
