Many believe that drinking water is governed by a single, fixed rule such as "8 glasses a day," but the health reality is far more complex than that. A body's fluid requirements vary from one person to another based on age, weight, physical activity, and even the climate they live in.

A recent health report indicates that determining your daily water intake should not be arbitrary; rather, it depends on a simple equation that takes into account body weight and activity levels throughout the day. This approach helps achieve better and more accurate hydration for the body.
Sources clarify that the body does not obtain fluids from water alone, but also from food—especially fruits and vegetables—as well as other beverages. This makes counting "liters of pure water" on its own insufficient for evaluating true hydration.
Experts also warn that feeling thirsty is not always an early indicator, particularly among the elderly. This makes relying on daily habits more important than waiting for the sensation of thirst. Conversely, excessive water consumption can lead to disruptions in the body's electrolyte balance if not done mindfully.
Nutritionists emphasize that the best way to maintain fluid balance is to distribute water intake throughout the day and monitor urine color as a simple indicator of hydration levels, as a pale color typically indicates good hydration.
They also recommend adjusting fluid intake on hot days or during exercise, rather than strictly adhering to a fixed number, because the body's needs constantly change depending on the surrounding conditions.
