What is Dehydration?

Updated: Jun 30, 2021

Every living creature needs water to survive. Yet sweating, peeing, vomiting, or having diarrhea can cause a loss of water, further increasing your liquid needs, in a complex physiological process making you feel thirsty.


If you’re thirsty, that’s the clearest sign you’re dehydrated, which means your body doesn’t have enough water to function properly.

Being dehydrated doesn’t just mean your body is losing water it also means you're losing salt and potassium, which help your body breathe, move, and do all the other things it needs to do to stay up and running.
