Aim: To decide whether drinking water is either effective in providing health benefits to human beings or increases the likelihood of injury and death among consumers. Design: A systematic review of randomised controlled trials was conducted according to standard ised criteria. Data sources: Medline, Embase, and the Cochrane Library Database. Study selection: Studies containing “water” and “health” in the abstract, thereby indicating their dealings with health associated benefits and risks of water consumption. Main outcome measure: Major changes in the status of health, as measured with various scores available on the internet (pick any of interest). Results: Studies on the effects of drinking water on health that meet the generally accepted criteria of evidence based medicine could not be identified. Conclusions: As with many interventions intended to prevent ill health, the effectiveness of drinking water has not been subjected to rigorous evaluation by using randomised controlled trials. This matter of fact is discussed using concepts from such diverse backgrounds as epidemiology (cohort effect), public health (need for large scale studies), medical economics (need to save money), medical ethics (bias effects) and social science (the dangers of medicalisation of drinking water). Within this complex framework it turns out that evidence based medicine is not without risks and sideeffects. It should therefore always be applied with reason.
