Drinking 8 Glasses of Water Could Kill You

Drinking water when your body does not need it could kill you,a new study shows!

Doctors, scientists and our loved ones all
remind us of the need to drink eight glasses of water each day. But is there any truth behind the tale that it's good for us? Apparently not, as experts have now warned refreshing yourself when you're not thirsty could actually kill you.

 Drinking excess liquid activates a protective swallowing inhibition within the brain, a study found. But forcing yourself to drink more than what your body needs overrides the mechanism and puts people at risk of water intoxication, scientists claim.

  Hyponatremia - where vital levels of sodium in the blood become abnormally low - occurs when too much of the liquid has been consumed. It can cause lethargy, nausea, convulsions and even lead to a coma and if left untreated, it can lead to death within just a matter of hours.

 Lead researcher Dr Michael Farrell, from Monash University, Melbourne, said: 'If we just do what our body demands us to we'll probably get it right - just drink according to thirst rather than an elaborate schedule.

 'Here for the first time we found effort-full swallowing after drinking excess water which meant they were having to overcome some sort of resistance. 'This was compatible with our notion that the swallowing reflex becomes inhibited once enough water has been drunk. '

 'There have been cases when athletes in marathons were told to load up with water and died, in certain circumstances, because they slavishly followed these recommendations and drank far in excess of need.'

If water enters the body more quickly than it can be removed then electrolytes in the blood become diluted.
This causes the water to travel through the blood and pass into cells and organs such as the brain - affecting its ability to function.
