I've heard that if you shower right after you workout, its bad for your heart. Is that true, or is it a myth. It doesn't really make sense to me because swimming is a workout, and youre always in the water.

It's a myth... and a very dumb one if that lol.  Whoever told you that must be on them crazy pills :)

Wow......I've never heard that one before.  That must have been started by the same people who claim when you stop lifting all that muscle turns to fat :-)    Absolutely not true.  What is true is you'll be one stinky bacteria laden person if you don't shower after you lift :-)

mmmm yeah i agree. The reason people say its bad for you heart because they say your heart is still pumping really fast and cold water is bad for it. But I always cooldown at the end of my workouts so it's never a problem. I was just curious. 

It's a real trend today to say that something is bad for you. Almost everything has something 'bad' on it according to the 'experts'. I wouldn't pay too much attention to it if I were you.

That is a myth! I wouldnt believe anything that guy says lol that is nonsense!

Yeah this has to be a myth... sounds very bizzare

This must be a myth.  The only way it can be bad for your heart is if you hop into a freezing cold shower which shocks the body.  In this case, I would have to then say it's bad for your heart whether you just finished a workout or just woke up from a nap.

Complete myth, in fact, studies have shown that a cool shower post-workout can help reduce DOMS the next day. I usually take a warm/hot shower after to help relax my muscles...it's all personal preference. I NEVER heard of someone dying in the shower right after a workout, not that it doesn't happen, but you think it'd happen more often if this were true.

AHHAHAHAHa... First time to heard that! I usually take a hot shower for 5 minutes after intense workout...and still nothing happens to me at all.
