What is the minimum amount of water an individual should consume daily to maintain proper body function?

The recommended daily water intake varies depending on numerous factors such as age, sex, activity level, and climate. However, general guidelines suggest that an individual should aim for about 3 to 4 liters of water per day to maintain proper bodily functions, which includes hydration, temperature regulation, and aiding in digestion. This amount also accounts for water obtained from beverages and food consumed throughout the day.

An intake of 8 to 10 liters of water is often considered excessive for most individuals, as it can lead to water intoxication, a condition where the balance of electrolytes in the body is disrupted due to dilution of sodium levels. The upper limit of daily water consumption for healthy adults is typically around 4 to 5 liters, making lower amounts like 3 to 4 liters much more realistic and safe for maintaining hydration and bodily function under ordinary conditions.
