Introduction
Water is essential for life, but is it possible to drink too much of it? The answer is yes. While water is essential for hydration, drinking too much can lead to a condition called water intoxication, also known as hyponatremia.
Recommended Daily Water Intake
The amount of water a person needs to drink each day varies depending on a number of factors, including age, activity level, climate, and overall health. However, general guidelines have been established by reputable organizations:
- The National Academies of Sciences, Engineering, and Medicine (NASEM) recommends that adult men drink about 15.5 cups (3.7 liters) of fluids per day, including water, other beverages, and food.
- Adult women should aim for around 11.5 cups (2.7 liters) of fluids per day.
- Children and adolescents have different recommendations based on their age and activity level.
Risks of Overhydration
Drinking too much water can lead to water intoxication. This occurs when the body’s sodium levels become diluted, causing the cells to swell. Symptoms of water intoxication include:
- Nausea and vomiting

In severe cases, water intoxication can be fatal.
