Well, you have to keep in mind that there is much more danger of dehydration than there is of hyponatremia, especially among the new riders. Hyponatremia isn't really much of a factor until exercisers (cyclists, runners, etc.) are into the advanced levels of their sport (marathons, ultracycling, etc.) and when we get to that level, we should know enough to make ourselves aware of the articles and information out there about those things (like the articles I posted).

The average recreational cyclist or commuter isn't likely to encounter a problem with hyponatremia.
