Tag: 4 litres water

The U.S. National Academies of Sciences, Engineering, and Medicine recommend a daily fluid intake of approximately 3.7 liters for men and 2.7 liters for women from all sources. Therefore, deciding if it is okay to drink 4 litres of water a day depends entirely on your specific activity level, health, and environment.

According to the National Academies of Sciences, an adequate daily fluid intake is approximately 3.7 liters (15.5 cups) for men and 2.7 liters (11.5 cups) for women. Exceeding this amount, especially over a short period, can have significant health effects, both positive and negative.
