In my experience it takes some time for my body to become accustomed to dealing with high levels of fluid intake and loss. The effect is that if I did no prior preparation, I would almost certainly be dehydrated at some level during the first few days of a flying session, comp or whatever. Despite the level of fluid intake being high enough, it simply passes through my system and exits the pee-tube, without being absorbed. Imagine pouring water on a totally dry pot plant... it all runs out the bottom until the soil becomes moist, then it is much more readily absorbed.

If I were to begin my preparation on the morning of a flight, it is already too late. My usual plan is to begin a well-above-average intake of water a few days before I leave for a comp, then my system is ready to handle the volume when the time comes. I might add that my work is quite physically active, and I still find gliding another big step up in fluid requirements. If you have a sedentary-style work then it probably means an even greater change.

Any medical comment on this idea?

That is indeed my experience. When working in ceilings and in circumstances that are very hot, I find I cannot drink enough cold water. I like to drink
cool water but will drink warm water in preference to icy cold.  Even then
sometimes I cannot keep up and I judge my hydration by the amount of times I
wee.
