I talked about "10 Things You Might Not Know About Caffeine" a week ago, and now lets discover that any ground is behind the myth of "drinking coffee causes dehydration."
Researchers at the University of Birmingham, U.K., has recently published a study on the fluid levels of 50 men who are habitually consuming 3 to 6 cups of coffee every day, which considered as moderate coffee drinker.
In the study, the 50 participants completed two phases of experiment.
Phase 1: They drank coffee as their main source of hydration for 3-day.
Phase 2: They drank equal amounts of water for another 3-day.
The result suggested that coffee, when consumed in moderation, provides similar hydrating qualities to water. Hence, the myth about "coffee causes dehydration" is actually NOT TRUE.
Another study also found that caffeine didn't hinder hydration among athletes who consumed caffeinated beverages after exercising.
Please keep in mind that these findings DON'T suggest that coffee is = to water!
Too much coffee can lead to jitters. And most experts agree that water or sports drinks are best for re-hydrating after fluids have been depleted.
Just like everything, it's best to limit caffeine to moderate levels in order to steer clear of jitters and interruptions to sleep.
