20 Surprising Things That Are Actually Damaging Your Kidneys

10. Too Much Fluid Intake

60% of the human body is water, and it has many vital functions. Since our bodies can't hold onto water and an adult can lose up to 3 liters of water every day, we must drink enough water to stay healthy and alive. Although we need to avoid dehydration, excessive fluid intake can also be harmful to our bodies.

A study found that excessive fluid intake can cause a higher risk of cardiovascular death. You may think it's not common to ingest too much fluid. Well, actually, almost all foods contain fluids, especially fruits and vegetables.

It's true that different people require varying amounts of fluid intake. For example, people on high-fiber diets, pregnant and breastfeeding women, and those who live in warm places may need to drink more water than others.

However, drinking too much water in a short period of time can lead to hyponatremia (water intoxication). When this occurs, the kidneys can't excrete enough fluid. Then it can result in headaches, blurry vision, seizures, brain swelling, and even death.
