Drinking water is important, and many people do not drink the recommended 2L per day. Why, then, do we have to constantly remind ourselves to drink enough to meet those requirements?

Question

In other words, why is the body’s “red flag” so different than that for hunger? Why is the body’s mechanism to remind us to eat more conspicuous?

Answer 1

I think that any recommendation put out to drink a certain amount is nonsense. You should drink enough so that you aren’t thirsty and that’s all you need to drink. Your body is a well honed mechanism set up over tens of thousands of years, and it knows what it needs.

So when you are thirsty, drink some water. When you aren’t thirsty, don’t. That’s my recommendation.
