Too much water can be bad for you

London - Too much water can cause the blood to become too diluted which, in rare cases, can be fatal.

The condition – hyponatremia – leads to cells swelling up with the excess water.

The product is used in plastic drinking bottles and in the lining of some canned food containers, among other purposes.

Although most of the body’s cells can cope with this swelling, those in the brain are pushed against the skull.

In mild cases this can cause headaches, confusion and nausea but if serious can lead to fits, organ failure and even death.

The condition is rare and normally only occurs in athletes who drink large volumes of water while they exercise.

But experts warn that just drinking slightly too much water isn’t good for our bodies.

Recently some have also cast doubt on advice that we should drink eight glasses a day, saying we get much of our intake from fruit and vegetables. - Daily Mail
