Could you point me to any peer reviewed articles in medical journals that serve as the basis for the modern mania with hydration?
And yes, it is as simple as feel thirsty, drink - hardware and software 3.5 million years in the making and fully debugged.
Evolution never gets anything that is (even metaphorically) "fully debugged". In fact we can die of thousands of issues related to a non-fully debugged body -- especially when you take into account the changes in living conditions in the past 5-10.000 years with agriculture and then city life. Evolution "worked" for million years with the assumption of nomadic primates in an natural environment.
This comment simply disqualifies you from having an opinion on the matter -- as does the "if you feel thirsty, drink".
Not only because the feeling of first comes AFTER you actually need to drink (which is not important for the general population, but very important when you're an athlete in the MIDDLE of an effort), but also because there are people who don't get proper thirst signals (not just some with rare conditions either, the elderly are known as one such category).
As for "peer reviewed articles in medical journals" you can search for yourself -- there are hundeds on the subject of hydration and dehydration and water consumption regulation--, but the phrase "serve as the basis for the modern mania" means you have a confirmation bias so I don't think reading them will do you any good.

I specifically asked for peer reviewed papers that serve as a basis for the recommendations on the amount of water a person needs to drink. You failed to deliver and so are not qualified to have an opinion on the matter. I'll give you hint - there aren't any papers that say an adult needs to drink 2.5L a day. New Scientist had an article where they questioned the hydration mania mantra and stated there was no basis for it.
It's not 'too late' if you feel thirsty. What - you think, that people will keel over and die or fall to the ground with uncontrollable muscle spasms and foaming at the mouth if they feel thirsty? What a load of tripe. If you drink water, it will start to hit your bloodstream in 5 minutes. Half the amount will have found it's way into your bloodstream in 11-13 minutes. The 'too late' nonsense applies to athletes in the process of lengthy competition who don't want their performance to deteriorate and impact their performance. Such people do not need a silly gadget to tell them they need to take a drink, nor are they going to carry one. Neither do people not engaged in extended competitive athletic activity.
What next, a USB connected lunchbox to remind you to eat? You might need one and a cup to remind you to drink till it's coming out of you gills but I have managed to get by without either, including 30 years or so living in Australia where it is both very dry and often quite warm.

There are no "recommendations on the amount of water a person needs to drink" (aside from BS pop articles mentioning "8 glasses per day" etc). The water a person needs to drink differs depending on age, weight, diet, activity/exercise level and even the environment.
And even if what you NOW ask made sense, you sure didn't ask for "peer reviewed papers that serve as a basis for the recommendations on the amount of water a person needs to drink" in your previous comment.
You asked for, and I quote: "peer reviewed articles in medical journals that serve as the basis for the modern mania with hydration".
Which the studies detailing insufficient hydration in large parts of the population and the effects on dehydration, like I linked to, cover fine.

Depending on the activity (and presence of other conditions) they can do just that. In fact people DO just that a lot of times when dehydrated -- faint, feel sick, get headaches, etc. And in another common case, people not hydrated properly will perform worse in their activity (e.g. long distance runners, cyclists, etc).
In any case, you are obviously constrained by a lack of imagination of other people's needs (and possible medical conditions). You're also on the false impression that natural signals like "thirst", "satiation" etc work perfectly to regulate drinking and eating, which has been proven time and again that it is not the case.
I've said enough, and I'm not interested in further trying to convince you. Whatever works for you.

Seriously, this is too much. We must need an app to remind us to drink?!?!
Obviously you don't. It's for people with either thirst regulation issues, or more exciting lives (athletes, etc).

Next time I have a hair that needs splitting, I'll look you up.
What I was born with works for me just fine, thanks.
