People with full bladders make better decisions

London: Considering an expensive purchase? Drink a bottle of water first, for a study claims that people with full bladders make better decisions.

Researchers have found that the brain`s self-control mechanism provides restraint in all areas at once, and people with a full bladder are able to better control and "hold off" making important, or expensive, decisions, leading to better judgement, `The Daily Telegraph` reported.

The researchers from the University of Twente in the Netherlands have linked bladder control to the same parts of the brain that activates feelings of desire and reward.

The study, published in the `Psychological Science` journal, also concluded that just thinking about words related to urination triggered the same effect.

Dr Mirjam Tuk, who led the study, said that the brain`s "control signals" were not task specific but result in an "unintentional increase" in control over other tasks.

"People are more able to control their impulses for short term pleasures and choose more often an option which is more beneficial in the long run. The brain area sending this signal, is activated not only for bladder control, but for all sorts of control.
