German Pontser, an associate professor at Duke University in the United States, and colleagues studied how much water humans, chimpanzees, gorillas and bonobos need for normal life.

The study covered 309 people from different occupations (eg, hunting and fruit picking, Khadza tribes living in roughly the same conditions as wild primates), ethnic and racial groups, and 72 monkeys living in the wild and in the zoo.

To determine how much water the body consumes each day, biologists monitored the amount of the isotope in their sweat and urine. It was found that, on average, humans need up to one liter of water per day for normal life, and primates need up to six liters (with the addition of mass difference). This ratio is typical for both sedentary people and those who spend most of their time hunting, gathering fruit and looking for food.
