Hydrating the body after overnight water loss (approximately 300 to 400 ml) is an excellent practice well supported by health professionals, as noted by the Cleveland Clinic (expert opinion). As for the proposed volume, the U.S. National Academy of Medicine (consensus report) suggests a daily fluid intake of 2.7 to 3.7 liters, but this includes all beverages and water contained in food. Drinking 2.4 liters of pure water in just 10 hours is therefore a very high target, sometimes disproportionate for smaller or sedentary individuals, as ideal hydration remains highly individual. Furthermore, no clinical study (RCT) validates the benefit of restricting or concentrating nearly all fluid intake within this 10-hour time window to optimize health. However, the emphasis on water quality is sound: the World Health Organization (consensus report) and several observational studies confirm that the calcium and magnesium in hard water are highly bioavailable and support our overall vitality.
