It&#8217;s a recommendation that&#8217;s rarely challenged and championed by many health advocates. But where exactly do the numbers come from and why? Dr. Margaret McCartney, a general practitioner from Scotland, is challenging the 8-glasses-a-day rule and recently published her thoughts in an article entitled <a href=\"http:\/\/www.bmj.com\/content\/343\/bmj.d4280.full?keytype=ref&amp;ijkey=ZD92BtTrOIdw3Rv\" target=\"_blank\">&#8220;Waterlogged?&#8221;<\/a> in the <em>British Medical Journal<\/em>.<\/p>\n<p style=\"text-align: justify;\">Dr. McCartney describes the notion that &#8220;we don&#8217;t drink enough water&#8221; as &#8220;thoroughly debunked nonsense,&#8221; and that having too much water could be unhealthy. She notes that the recommendation to drink six to eight glasses of water a day is supported by many health officials and organizations, including the NHS (National Health Service). The <a href=\"http:\/\/www.nhs.uk\/Livewell\/Goodfood\/Pages\/eight-tips-healthy-eating.aspx\" target=\"_blank\">NHS Choices website<\/a> even states on its website that we should &#8220;try to drink about six to eight glasses of water (or other fluids) a day to prevent dehydration. When the weather is warm or when we get active, we may need more.&#8221;<\/p>\n<p style=\"text-align: justify;\">McCartney&#8217;s claim is bold, no doubt, but she cites two major sources as evidence. First, Heinz Valtin wrote in the <em>American Journal of Physiology<\/em> in 2002 that that there is &#8220;no scientific evidence that we need to drink that much [water]&#8221; and that the &#8220;recommendation could be harmful.&#8221; Also, a 2008 editiorial in the Journal of the <em>American Society of Nephrology<\/em> stated that &#8220;there is no clear evidence of benefit from drinking increased amounts of water&#8230;there is simply a lack of evidence in general.&#8221;<\/p>\n<p style=\"text-align: justify;\">Others are rushing to support Dr. McCartney&#8217;s assertions and are relieved that she&#8217;s contributing to this ongoing conversation. <em><a href=\"http:\/\/www.guardian.co.uk\/lifeandstyle\/2011\/jul\/13\/myth-eight-glasses-water-day\" target=\"_blank\">The Guardian<\/a><\/em> notes that &#8220;we humans are pretty good at regulating our own water intake. When we need to replace fluid there&#8217;s this highly accurate mechanism called thirst that prompts us to have a drink.&#8221;<\/p>\n<p style=\"text-align: justify;\">A unique idea&#8230;drink only when you&#8217;re thirsty.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>At some point in our lives we&#8217;ve heard that we should drink around six to eight glasses of water a day.
