Respectfully, what on Earth are you talking about? OP has only indicated that they're trying to be health-conscious by maintaining proper hydration - the weird "societal pressure" angle is being superimposed by you. As I alluded to in my previous comment, it's easy to ignore mild dehydration and sometimes a conscious effort is needed to maintain optimal intake. "Drink when you're thirsty" is fine in a vacuum, but to distill (no pun intended) hydration advice down to just that is to ignore how people work in real life.

I don't know why you're bringing up hyponatremia. Water toxicity is exceedingly rare and one would need to consume an inordinate amount of water in short time before it becomes "unsafe." You're unnecessarily fearmongering and pushing misinformation when you don't know what you're talking about.

Also, there's no "water-pushing" conspiracy at play here. It's just a reality that most people don't consume as much water as they ideally should, and as a result people sometimes draw attention to that reality as a means of improving the general health of society.
