Older adults are generally recommended to consume around 1500 mL of fluid each day. This recommendation is based on the physiological changes that occur with aging, which can affect fluid balance and increase the risk of dehydration. As people age, their sense of thirst may diminish, and their kidneys may become less efficient at conserving water.

Maintaining adequate hydration is crucial for overall health, including supporting proper kidney function, regulating body temperature, and facilitating other bodily processes. The recommendation of 1500 mL is considered a baseline to help ensure that older adults remain hydrated, as individual needs may vary based on factors such as activity level, climate, and underlying health conditions.

In contrast, the lower values of 1000 mL and 1200 mL may not adequately meet the hydration needs of many older adults. While the upper value of 2000 mL can be appropriate in certain contexts, it might be excessive for some individuals, particularly if they have certain health conditions that require fluid restriction. Thus, 1500 mL serves as a balanced guideline that promotes hydration in older adults.
