"This, coupled with the powerful stimulating effects of caffeine, increases stress and causes failures in concentration." Sarah Schenker, a dietician for the British Nutrition Foundation, said there was nothing wrong with people drinking three or four cups of coffee a day - provided that they also drank water or other decaffeinated drinks to compensate. She said: "If you only drink caffeinated drinks then you will become mildly dehydrated. It has been shown that just 2% dehydration does affect concentration, and also makes you irritable." The study found 93% of workers surveyed drank at least one caffeinated beverage a day.“

"However, our findings need to be replicated and possible adverse effects on other health aspects should be considered in the choice to consume coffee."
