There's no mention of the fact that the food we eat is also a significant source of water.

This is a common misunderstanding around those "you need X glasses of water per day" recommendations -- much (sometimes, most) of your needed water comes in your food and doesn't need to be consumed as a separate thing.

And even though there are other health considerations to them, water you take in the form of coffee, tea, soda, etc., also counts.

https://xkcd.com/1708/ I often heard really exaggerated advice about how much water to guzzle every day. It got crazy. One day several years ago, a nurse was taking vitals on me and told me to drink, I don't know, 48 cups per day or something? It was huge. And I regarded her with incredulity. So upon being taken in to see the doctor, and this was a physician that I really trusted and had a good long tenure, I repeate…

I wonder if that nurse was confusing "cups" with "ounces".

Or maybe “four to eight” cups. The idea of drinking almost 12 liters of water each day is pretty amusing.

Given how critical this is I suspect your body is better at it then you are... I'd say "Drink when you are thirsty".

And when your pee is yellow / yellowish ...

And double check intake if you get a headache (typical symptom of dehydration).

Drink when you're thirsty. Most anything above that is probably fine.

As we age our "thirst response" becomes less reliable. I really don't get thirsty until I am starting to become dehydrated. It's good to have a guideline to inform my self-imposed daily drinking regimen.(which I have a hard time keeping)

Also, I've found, temperature can have a huge influence. I like to do winter camping in the middle of nowhere in the mountains. I was surprised to discover that when I'm in freezing conditions like that, I simply won't feel thirsty -- apparently ever -- so I set a timer to remind me to drink.

I learned this the hard way on the third day of my first such trip, when my urine had become brown due to dehydration.

It is probably best to follow real information then.

Note that while your thirst response may be declining as you age, mine hasn't.

Annicdodes aren't data, mine or yours.

IMHO the 8x8 myth may or may not be optimal guidelines for you as they aren't based on anything but rumors.
