Everyone who drinks coffee knows that it makes you have to pee, right?
You may also be aware that scientists are heavy coffee drinkers.
Thus, when I am in meetings that run longer than an hour and a half, starting around the 50min mark, people start taking ‘bio breaks.’
This anecdata would support the idea that coffee/caffeine dehydrates you by acting as a diuretic.
Well, this is why anecdata is dangerous to rely on.
I heard it on NPR (who did good by linking to the original PLoS study in their article!) that, caffeine, “when consumed in moderation by caffeine habituated males provides similar hydrating qualities to water.” (Source: Killer, Blannin, and Jeukendrup PLoS 2014 since PLoS stands for Public Library of Science, the article is freely available for all to read!).
It’s practically a health drink! It’s like Gatorade for parents and scientists!*

*Disclaimer: DO NOT dump an urn of hot coffee over the head of anyone as a celebratory gesture as is frequently done with Gatorade. Coffee is hot and can result in severe burns.
