There is no evidence that links moderate coffee drinking with dehydration, British researchers say.
Instead, for regular coffee drinkers, multiple cups of java contribute to daily fluid requirements.
"Despite a lack of scientific evidence, it is a common belief that coffee consumption can lead to dehydration and should be avoided, or reduced, in order to maintain a healthy fluid balance," lead author of the study Sophie Killer said in a press release.
"We found that consumption of a moderate intake of coffee, four cups per day, in regular coffee drinking males, caused no significant differences across a wide range of hydration indicators compared to the consumption of equal amounts of water."
The study was published in the journal PLOS ONE.
