Drinking eight glasses of water a day is a theory that doesn't hold, well, water, says an article in the British Medical Journal.

Margaret McCartney, a family doctor based in Glasgow, Scotland, says that recommendation is "not only nonsense, but thoroughly debunked nonsense." She added that the benefits of water are often exaggerated by "organisations with vested interests" such as bottled water brands.

In her article, which appeared in the publication Tuesday, McCartney points out that research shows drinking when not thirsty can impair concentration, rather than boost it, and separate evidence suggests that chemicals used for disinfection found in bottled water could be bad for your health.

McCartney also warns that drinking too much water can lead to a rare but potentially fatal condition called hyponatraemia, which sees the body’s salt levels drop and can lead to swelling of the brain.
