Does being submerged in water stop bleeding?

I can't find information, as in, if you cut yourself and put your hand into a full sink of water, will it make it bleed more, or make it stop bleeding??

Please include your sources!! Thanks!! :)

I know how to treat cuts. I was just having a discussion with someone and I wasn't positive because I had remembered something about suicide in bathtubs.
I've never cut myself and run to fill the sink up with water to dunk my hand in, I was just WONDERING.

The answer is: It depends.

Depends on your platelet level (hemophilia, etc) and size of the cut. Major bleeding cuts need pressure, which water doesn't generally exert enough of. However, if you put your hand in a tank of pressurized water... or in several meters deep of water, the water will exert pressure on the cut keeping it from bleeding. It will continue bleeding once your body becomes accustom to the pressure.

It's a ridiculous answer, I know.

Fact of the matter is, platelets become activated when they're exposed to one of several stimuli. They -can- clot underwater, but the process is greatly impeded.
