I drink a lot of water. I keep a 2 liter bottle on my desk and refill it 2-3 times over the course of a work day. Sometimes more, sometimes less. I also drink tea and coffee, and sometimes beer in the evening.&lt;p&gt;I drink water because I want to? It’s not exactly being thirsty (I sometimes get thirsty when I’m out and about for extended periods; that feels different). It’s just wanting to drink water, and water being there. Should I be worried? Should I be limiting myself to only drinking water when I feel truly thirty?&lt;p&gt;I’m also an amateur marathon runner, and I reckon I probably drink much less liquid while running a marathon than in a comparable 3.5 hour block working (although I drink a lot of water and sports drink after finishing).&lt;p&gt;Edit: In case it matters, I don’t drink water because I’ve bought into “stay hydrated” hype. I’m well aware that I drink more than enough water to meet my body’s needs. I just like it.</text><parent_chain><item><author>8372049</author><text>If you can back that up with a source, please do so. In any case, my point isn&amp;#x27;t about margins.

<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>beeeeerp</author><text>Maybe it’s confirmation bias, but I have heard of very few over-hydration cases whereas medical dehydration seems pretty common.&lt;p&gt;Granted the pressures for dehydration are a lot more common (hiking with too little water, running competitions, maybe little access to water in a hot climate, etc). Once one has ample access to water, I doubt there is much pressure to keep drinking to over-hydration.</text><parent_chain><item><author>8372049</author><text>If you can back that up with a source, please do so.
