Clearly having nothing better to do, University of Bristol experimental psychologist Peter Rogers measured the accuracy of volunteers on a simple prompted button push test before and after they drank cups of cold water.
Those that felt thirsty and had a drink of water did better than those who stayed thirsty, but those who weren’t thirsty and had a drink did worse.
The groundbreaking conclusion is that drinking when your thirsty is good, but drinking when you’re not causes confusion. Presumably because you’re sat there thinking “why did I do that, now I have to go to the loo.”
So if in doubt maybe wait until after the tricky technical bit before you have a drink. Not too long though, as dehydration causes even greater disorientation.
