John,
Hyponatremia is a concern for any prolong heat exposure, but also worrisome
is Hypernatremia (too high of a salt level).
I'm stunned by the dangerous quantity of salt you are suggesting people
consume for a 2 hour long Ultimate game in the evening.
Your recipe includes 2 Tablespoons of table salt and 2 Tablespoons of
Morton's Lite (50% Na+). The end result is 40-45 grams of sodium. That is
roughly 15 times what is needed and dangerous. In addition to the
possiblility of hypernatremia, most who drink such a high concentration of a
sodium drink will likely suffer GI distress.
Most people would be fine with plain water for the short duration of the
game. Encouraging people to use Gatorade or other sports drinks is
reasonable. Suggesting a recipe with a teaspoon of Morton's Lite is
reasonable, but your recipe will not serve people well.
Respectfully concerned,
David Kaminski
