Does Coffee Really Dehydrate You?
Over the years, I have always heard that coffee dehydrates you and that it is bad for you. However, with new research, more and more studies are finding that coffee is very beneficial to one's health.
Contrary to popular belief, coffee does not dehydrate you at all, instead it does the opposite according to a new study released on January 9, 2014.
Researchers from Birmingham University School of Sport and Exercise Sciences took 50 healthy men and had half of them drink 4 mugs of black coffee for three consecutive days while the other half drank the same amount of water, and then they switched.
"Caffeine really had absolutely no influence on hydration status," concludes Douglas Case of the University of Connecticut, a researcher that reviewed the paper.
"It's well understood that if you drink coffee habitually you can develop a tolerance to the potential diuretic effects of coffee," says study author Sophie Killer, a doctoral researcher at Birmingham.
Prior research has already chipped away at the dehydrating myth. For instance, one study found that caffeine didn't hinder hydration among athletes who consumed caffeinated beverages to rehydrate throughout practices in the heat.
Additionally, during exercise, caffeine is beneficial for endurance performance. Moderate coffee consumption actually contributes to our daily fluid requirements and does not lead to dehydration.
The mild, short-term diuretic effect of caffeine is not strong enough to counter-balance the benefits of fluid intake from coffee drinking.
After all, coffee is made up of 95% water.
