Most of us are familiar with the saying that you need to drink about eight glasses of water a day, but do you know that drinking too much water can do some major damage to your body?
Experts have warned that drinking eight glasses of water a day is not good for you after all, and could be harmful.
Water is important, but most of us probably don’t need eight glasses a day. In fact, scientifically speaking, there is no real evidence that suggests this number has any real benefit.
A hydration researcher at Stanford University, Stacy Sims said: “There’s no scientific method behind those numbers and the recommendation doesn’t take into account gender, environment, altitude, fitness level – factors that could affect fluid intake needs.”
Water is good, if it’s taken in the right amount. When it is overdone, it can be bad for your health.
In rare cases, drinking an extreme amount of water in a short time can cause the level of salt, or sodium, in your blood to drop too low. That’s a condition called hyponatremia (also called water intoxication). It’s very serious and can be fatal. Symptoms include confusion, headaches, nausea and bloating. In severe cases, hyponatremia can lead to seizures, organ failure and even death.In humans the kidneys control the amount of water, salts and other solutes leaving the body by sieving blood through their millions of twisted tubules. When a person drinks too much water in a short period of time, the kidneys cannot flush it out fast enough and the blood becomes waterlogged.
Drinking excessive amounts can also lead to loss of sleep as people have to get up in the night to go to the toilet.
Other studies show it can even cause kidney damage, instead of preventing it.
If you’re simply drinking too much water at once, you may end up peeing too much, and not absorbing any fluid.
