喝水的那些事：你做得对吗？

Is it true that drinking too much water is dangerous?
喝太多水真的有危害吗？

Fact. “Water intoxication” is common among marathon runners, but it can also happen to anyone who’s exerting themselves for an extended period and guzzling lots of H2O. Physical stress like exercise reduces the kidneys’ ability to send urine to the bladder for excretion. Drink too much, and fluid levels could build in your body and brain, making brain cells swell and leading to headaches, nausea, vomiting, disorientation, and in some cases, death. To avoid it, drink enough to quench your thirst, not gallons. And if you need to drink large amounts of fluid, use Gatorade, Propel, Powerade, or other similar drinks that have vitamins and electrolytes besides just water.
这是事实。“水中毒”在马拉松参赛者身上是很常见的，但是它在一些长期不断暴饮大量水的人身上也会发生。如运动这种身体压力降低肾将尿液输送到膀胱进行排泄的功能。喝太多水，身体和大脑中的液面就会上升，促使脑细胞膨胀一起头痛、恶心、呕吐、定向障碍、有时候甚至导致死亡。为了避免这种情况，喝足以解渴的水，而不是大量地喝。如果你需要喝许多水，那么就喝佳得乐，Propel，动乐或其他类似的除了含水外还含有维生素和电解质的饮料。
