Your answer is quite misleading and difficult to understand. As someone who doesn't have knowledge concerning anatomy and nutrition, I'm completely lost in your attempt to address the fact-check. If you provided some clarification about the terms you use (e.g., hyponatremia, water poisoning), then readers might be able to grasp your answer more thoroughly. Currently, I'd have to read all of the sources you link in your answer to understand the point you're attempting to make. So, perhaps, including summaries of the sources you link could be helpful to readers.
