Step-by-step explanation:
In 1976, the anthropologist Claude Paque published a paper on the water consumption of Saharan nomads. This paper, Water consumption in Saharan nomads. A remarkably reduced and constant consumption, considered the reasons why these tribes drank so little water in one of the world's hottest regions. The adaptability of these nomads is reflective in the water allocation reported by Paque, with it being half the consumption of the Europeans living in the same environment.1 Given that even in a harsh environment, the consumption of water can be minimal, why do we insist on drinking such large volumes of water every day?
Australian health and dietary authorities currently encourage Australians to consume eight glasses, or two litres, of fluid daily for optimal health.2 This has been misinterpreted to mean two litres of water specifically and it has driven a steady growth in the use of bottled water over the years. Drinking water is healthy; it can contribute to weight loss, reduce the consumption of sugary beverages3 and − when consumed out of a bottle − can be healthier still, at least according to the water bottle industry.4 Thirty years ago you didn't see a water bottle anywhere, now they appear as fashion accessories. It supports the emergence of a new status;5 as May called it, “the new cultural class”.6 As tokens of instant gratification and symbolism, the very bottle itself is seen as cool and hip.7 Glamour has played a pivotal role. The use of water in weight‐loss programs has given added impetus to the notion that drinking large volumes of water a day will help lose weight. This is partly true, but it requires a low‐calorie diet in the same way as any other weight‐loss program. Research revealed that the inclusion of high volumes of water does nothing more than reduce the appetite.3 Further, Dr Victoria Potter noted that consuming water in food eaten had a greater benefit in weight reduction than avoiding foods altogether.8
Heinz Valtin posed the question, “Why do we need to drink eight glasses of water a day?”9 In a recent article by Dr Margaret McCartney in the British Medical Journal, the notion of needing to drink large volumes of water for health had been reinforced by the National Health Service (NHS) in Britain, without any substantial evidence to support it.10 There are institutional recommendations in Australia as well, for instance, the National Health and Medical Research Council (NHMRC) recommends a similar quantity of fluid to that discussed by Valtin. McCartney further showed that despite the claims of bottled water producers that more water is required, evidence suggests the over‐consumption of water, particularly in children, could be detrimental. Both Valtin and McCartney consider the recommendation of eight glasses or two litres of water a day to be driven by vested interests, rather than a need for better health. Even so, from where did this recommendation originally stem?
A bit of history
The recommendation to consume large quantities of water can be traced back to the 19th Century, to the ‘hydropathists’, those alternative practitioners who considered that water had the power to cure any ailment.11 Hydropathy was a discipline developed and promoted by Vincent Priessnitz (1799–1851), who learned of the apparent curative effects of water as a child. Over the years he experimented with his ‘water cure’ on farm animals and his own family and through further work and experimentation he began dispensing his water cure through an institution he founded in Graefenburg in Austria in 1829. The popularity of his treatment quickly spread around the globe and water sanatoriums sprang up in Europe, the US and Australia.
The hydropathy method involved the use of quite heroic water therapies, but in addition the patient was required to drink copious amounts of water over the course of the day along with treatments of cascading waterfalls or sitz baths. Priessnitz considered the consumption of water an essential part of the process and the ingestion of large volumes “brings bad stuff out of the system”.11
One of hydropathy's strongest supporters, the Australian hygienist John Hern, considered it “one of the most valuable curative agents of the time”.12 His method required his patients to drink “the only real drink – water” the equivalent of 1.1 to 1.7 litres a day.12
Science steps in
Scientific endorsement of a minimal water requirement first appeared as a brief footnote in 1945, when the Food and Nutrition Board of the National Academy of Sciences in the US published its Dietary Guidelines. It recommended that, as the average male diet would consume 2,500 kilocalories (10,467 kilojoules), this diet would require 1 mL of water for each kilocalorie; consequently 2,500 mL of fluid should be ingested on a daily basis.13 This recommendation was repeated in the 1948 revision14 with no reference or authority cited in the calculation.
