Can you get brain damage from drinking too much water?

Drinking too much water can cause a condition called hyponatremia, which is a dangerously low level of sodium in the blood. This can cause a number of problems, including brain swelling and damage. In some cases, hyponatremia can be fatal.

However, it is important to note that hyponatremia is a rare condition. It is most common in people who have certain medical conditions, such as kidney disease or heart failure. Healthy people who drink a lot of water are unlikely to experience hyponatremia.

So, while it is true that drinking too much water can be dangerous, it is important to keep this risk in perspective. The benefits of drinking water far outweigh the risks. Staying hydrated is essential for good health, and drinking plenty of water can help to prevent a number of health problems, including constipation, kidney stones, and heat stroke.
