Under normal conditions, the recommended daily water intake for healthy adults is 1500-1700 ml.

A normal person needs 40 milliliters of water per kilogram of body weight per day, meaning an adult weighing 60 kilograms requires approximately 2400 milliliters of water.

Food typically contains about 700 milliliters of water, while the oxidation of carbohydrates, fats, and proteins in the body generates approximately 300 milliliters of water. Additionally, a portion of water is excreted through stool. Therefore, it is recommended that healthy adults consume 1,500 to 1,700 milliliters of water in addition to the water obtained from food.

It is important to note that the body’s water requirements are not constant. In hot or dry environments, it may be necessary to moderately increase water intake.

If severe symptoms such as nausea, vomiting, or diarrhea occur, water intake should be adjusted based on the severity of the symptoms and the specific circumstances.

In cases of severe liver, kidney, or heart failure, water intake must be strictly restricted according to the severity of the condition. Under such circumstances, water consumption should be guided by a doctor.
