Tag: Individual hydration

While the famous '8 glasses a day' rule is a simple guideline, many US adults consume an average of just 44 ounces of plain water daily, equating to a little over 5 cups. However, when people ask, 'is 3 cups of water good?', the short answer for most is no; personal hydration needs are far more complex and individualized.

According to the U.S. National Academies of Sciences, Engineering, and Medicine, adequate daily fluid intake is around 11.5 cups for women and 15.5 cups for men. Therefore, five glasses is often less than the recommended total fluid intake, and may not be sufficient for everyone, depending on individual factors.

According to the U.S. National Academies of Sciences, Engineering, and Medicine, the recommended total daily fluid intake from all sources is approximately 15.5 cups for men and 11.5 cups for women. This shows that a 10-cup target is a reasonable, though flexible, objective for many people.
