Water

Since our childhood, we have been told to drink water as much as possible. But do you know that too much water has its side effect too. While hydration is key to good health, excessive water consumption can cause water intoxication. This happens when extreme water intake dilutes the sodium in the body, resulting in an abnormally low blood sodium level. This in turn can lead to impaired brain function and even death. To make sure you re not consuming too much water, check your urine: If it s always transparent, reduce your intake.
