Prevent Hyponatremia By Drinking Only When Thirsty
Athletes should avoid forced hydration and drink water only when thirsty.
(HealthDay News) — Athletes should listen to their body and drink water only when thirsty to prevent exercise-associated hyponatremia or "water intoxication."
The new guidelines were developed at the International Exercise-Associated Hyponatremia Consensus Development Conference in Carlsbad, California, and published in the Clinical Journal of Sport Medicine.
The development of the new guidelines was prompted by the deaths of two high school football players from exercise-associated hyponatremia last summer, the researchers said.
"The release of these recommendations is particularly timely, just before sports training camps and marathon training begins within the United States — where the majority of [exercise-associated hyponatremia] deaths have occurred," the lead author of the consensus statement, Tamara Hew-Butler, DPM, PhD, associate professor of exercise science at Oakland University in Rochester, Michigan, said in a journal news release.
"Our major goal was to re-educate the public on the hazards of drinking beyond thirst during exercise."
Athletes and coaches must also be aware of the risks associated with "forced hydration" practices.
"Every single [exercise-associated hyponatremia] death is tragic and preventable, if we just listen to our bodies and let go of the pervasive advice that if a little is good, more must be better," Hew-Butler said.
The consensus statement also advises physicians that exercise-associated hyponatremia treatment should be based on the severity of patients' symptoms — not just their sodium levels.
