Why is my skin leaking out water?

when I was running one day I relized that my skin was leaking out water like I am a water ballon. Is this weird? Will I die soon of dehydration. Should I stop drinking water so none comes out anymore? Is there some medication that I can take to stop this? For some reason it only happens when I run so I think that I should stop running and excercizing and that would solve this problem.
