Writing in the Clinical Journal of Sport Medicine, the specialists said that "aggressive drinking to prevent dehydration is unnecessary and carries with it greater risk."
饮水过量的危害是严重的,范围为头晕,神志不清或恶心脑水肿,使大脑膨胀,由于多余的水分。至少有14名运动员 - 包括一个女人谁完成了海军陆战队马拉松赛于2002年后两天死了 - 被认为已经从运动中被称为运动性低钠血症或EAH条件时饮水过多死亡。
当过量液体积聚在体内钠的浓度急剧下降和肾脏将会超负荷,无法排泄的水负荷。细胞开始吸收水分。这可能会导致肿胀遍全身 - 最严重的大脑 - 这可能会导致癫痫发作,昏迷甚至死亡。
The dangers of overdrinking can be serious and range from lightheadedness, confusion or nausea to cerebral edema in which the brain swells due to excess water. At least 14 athletes — including a woman who died two days after completing the Marine Corps Marathon in 2002 — are believed to have died from drinking too much during exercise in a condition known as exercise-associated hyponatremia or EAH.
When excess fluids build up up in the body the concentration of sodium can drop precipitously and the kidney become overloaded and are unable to excrete the water load. Cells begin to absorb the water. This can lead to swelling all over the body — most seriously in the brain — which can lead to seizures, coma or even death.
