I think hydration is one of the most underestimated and most important pillars of health, and it might be pretty neglected:

(1) Dehydration is highly tolerable (like apoB), so people can get used and live with it, up to 15% loss of body weight in water, where 2% loss have an impact.
(2) Dehydration decreases cognition, mood, decreases athletic performance, worse kidneys, etc, in humans.
(3) Dehydration increase aging rate and decrease lifespan in mice.
(4) Dehydration increase with aging.
(5) Thirst and similar differ among people and subject to distraction.

Max upper limit of water excretion is 0.7 L/h with normal kidney function.

The continuous hydration monitors in development and use seems very important especially (5) and similar.

It’s available and used widely – Non-invasive Hb trackers can also indicate hydration levels (there are many).

Suboptimal hydration remodels metabolism, promotes degenerative diseases, and...

Tip for large containers (as 0.5 L might not be enough).
