Can drinking 8 glasses of water harm your body!


It has been said that, drinking six to eight glasses of water can cut weight quickly. This is a notion which we are following since ages. A recent study has shown some different aspects which can change our thinking. Some researchers have challenged this notion of drinking eight glasses of water can bring harm to the body and people might suffer from water intoxication.

There is a mechanism found by Australia in human body which modulates fluid intake and stops over drinking, found out by Monash University researchers in Victoria.  This shows some shocking facts that drinking excess of water leads to water intoxication hyponatremia, a condition where level of sodium in the blood becomes low abnormally.

This will lead to few symptoms of lethargy, nausea, convulsions and coma. When we drink too much of liquid our brain activates swallowing inhibitions which maintains our volume of water in the body which are tightly mark, a study revealed.

Monash University Associate Professor, Michael Farrell said, “that we should drink when our body demands or when we feel thirsty than following an elaborated schedule.”

The study has been done by conducting an experiment with few participants and the team asked them to drink water under two conditions, one where they feel genuinely thirsty and other where they are forced to drink water in an excess amount.

There were three-fold increases in effort after over drinking, results showed. The team even used (fMRI) functional magnetic resonance imaging where they found out that the prefrontal areas of the brain were active when participants were forced to drink water with efforts.

Farrell said, “We observed something unexpected, when participants were drinking water with much efforts as if they are overcoming a resistance to drink excess of water as their swallowing reflex were becoming inhibited when they were drinking water persuasively.”

This study was published online the proceedings of the National Academy of Sciences.
