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

The mechanism to remind us that we’re hungry isn’t perfect.

It’s often thirst that we misinterpret as hunger.

Also that’s a recommendation not a requirement.

Drink when you’re thirsty, drink when you’re hungry (half the time you’re not hungry, just thirsty again).
