Surprise: Caffeinated Tea Does Not Dehydrate You
Fire up the kettle! Siobhan tweeted this study the other day, and I’m just tickled by it. It turns out that good old black tea—something I quite enjoy (for all you vegan challengers, I recommend trying it with some coconut milk for creamy deliciousness)—is just as hydrating as water.
Conventional wisdom says that caffeinated beverages are diuretics, i.e. that they cause water loss. But in research conducted on 21 male subjects—females weren’t used because of how menstrual cycles influence water retention (tell me about it, right?)—and controlled for all kinds of variables, it appears that tea is just as good as water when it comes to keeping us hydrated. The outcome according to the study abstract:
It was concluded that black tea, in the amounts studied, offered similar hydrating properties to water.
You might be thinking (as I was): How can that be? Drinking tea and coffee makes me pee all morning long! But then I realized something: Drinking anything makes me pee. Deep thoughts, I know.
So, have you avoided caffeinated tea because you’re worried about dehydration? Pass the cucumber sandwiches.
