Can you do cardio & shower with a Submariner?

[jsm5784]

Kind of a silly question, I know. But can you wear your Submariner while doing cardio/sweating (jogging, elliptical, etc.)? Can you also wear it in the shower? Any rules on maintaining it afterwards (pat dry, etc.)? I don't want it to smell moldy either. I'm assuming you can since it's a diving watch. However, I heard that the steam isn't good for it. These are just a couple reasons that persuaded me towards this specific Rolex model. Thanks.
