    Exercise-associated hyponatraemia and medication

    I had been a sufferer of exercise-associated hyponatraemia for at least a year, when I was living on a farm, as a direct result of drinking bore water. Unlike most bores which are overmineralized and dirty, these ones tapped into deep aquifers, that sourced ultra purified water. Because the water is trapped under deep layers of dolomites and Saprolites, the only way it can travel deeper into the earth is by passing through the micro pores of rocks, which results in micro filtration and ultra purification.

    But humans are adaptable to drinking pure water and pure water alone isn't going to make a normal person hyponatraemic, I had at one stage performing a labour intensive job as a tree surgeon. Also, because I have ADHD, I am medicated with adder-all.

    My situation was quite rare because I was living on a farm, drinking bore water and had a job pruning trees in residential areas, in the city. There, one would sweat heavily and would be drinking city water, which is one recipe for water that has a good mineral trace element content to it, but going home later that evening meant a diet of pure drinking water or cooking foods in pure water. This messed me up and affected my clear state of mind, often its a state of delirium that you start to feel as one of the typical symptoms.

    But then I also go back to the adder-all, which may have some role in making me vulnerable, because its an amphetamine and similar to the way ecstasy makes people become wate...

    Re: An Erroneous Conclusion

    We are pleased that Dr. Shephard agrees with our views. In contrast to his retrospective assertions, dispassionate analysis of what he has written in the past shows that his conversion to our drinking guidelines has occurred only with the publication of his most recent letter.

    Professor Shephard continues to be dismissive of most of the work of our Cape Town research unit [1, 2]. To our knowledge we have lar...

    Textbooks and drinking policies

    Dear Sir

    There is one recent textbook which explains the problem and promotes 'sensible' drinking policies.

    This was published in Dec 2006 and is planned to be readable for competitive and social athletes, coaches, physios and doctors b...

    An Erroneous Conclusion

    Beltrami and colleagues are correct to castigate the continued over-ingestion of fluids by marathon runners [1]. This may be a relatively new insight for investigators in Cape Town, where reports of over-hydration first surfaced. However, if the authors of the present report [1] will reread my textbook (wrongly described as published in 1974!), they will discover that it contains advice on fluid intake for distance runner...
