Though I do wonder if this will cause Camelback to rethink their ridiculous "hydrate or die" ad campaign and their reccomendation to consume one liter of fluid per hour during exercise.
Sheesh Keith, I expect more from you than this.
Did you sleep thru that class? but 0.6% of the population studied is not terribly significant.
Exactly. I bet a lot more people die from car accidents or smoking (or maybe even lightning strikes or shark attacks
- I'm being facetious).
As CB mentions, if you simply "drink when you are thirstly", you are already somewhat dehydrated, and even a relatively small loss of fluids can negatively impact performance. And last I checked, these people were doing a race.
As long as you are getting some sodium from food, fluids, or supplements (or perhaps all of the above) , then this shouldn't be a concern. People who get to around 120 are force-feeding water.
Exactly. Somebody like me who sweats a lot (shut up CB
) can blow thru 3 liters in 2 hours on a hot or humid day, and still lose weight due to dehydration.
I've done hikes where my wife and I are both in tanks and shorts, and sweating our asses off - and then we run into other hikers wearing jeans and long-sleeve shirts who aren't sweating at all. If somebody like that took in 3L of just water, they'd have a problem. Some folks just sweat a lot (shut up CB
), and also, some folks just aren't going very hard, and therefore don't sweat much, and therefore don't need to replace fluids they aren't losing.
From the study: Hyponatremia occurs in a substantial fraction of nonelite marathon runners and can be severe. Considerable weight gain while running, a long racing time, and body-mass-index extremes were associated with hyponatremia
If you are "running" a thon in over 4 hrs, then that explains why you might have this problem.
