Just listening to NPR (I’ll link in the story later once it is in the archive), where they were discussing people not drinking enough and getting dehydrated. Towards the end of the piece it said that while drinking caffinated drinks isn’t as good as water, it isn’t as bad as you might have thought, based on some new research. If you drink a litter of water, you may retain about 800 mils. If you drink a litter of tea, you may retain more like 700 mils. I’m curious where this research actually comes from, but it is interesting. Water is still better, but even coffee seems ok to keep you from getting dehydrated.
