What does drinking water when you wake up bring?
No fluid is taken in through the night while the loss continues. The first glass of the morning is a simple habit that starts the daily total early.
No fluid at all is taken in during sleep, but loss continues through breathing and sweating; by the time you wake up, the whole night has passed without fluid. The first glass of the morning is a practical start for that reason: it begins the day's total early and leaves no gap to be made up later.
