Why does coffee make you dehydrated when the base ingredient is water, yet drinking water on its own afterwards does the opposite?
In: Chemistry
Caffeine dehydrates you and coffee has more caffeine than water so coffee isn’t the best hydrator however if it’s all you had available to you it’s much better than nothing. People will say not to drink coffee how to combat alcohol poisoning because coffee dehydrates you but in reality since it is mostly water it’s still better than nothing. Water is the best bet in most situations but if coffee is what you have, drink it.
