Honestly, it's pretty shocking how ingrained it is. You hearit on TV, you see it in articles. But like I said, it's nonsense.For the most part, your body will tell you when you need todrink water, because you've got these wonderful, amazing,undervalued things--kidneys.
实话说，这谣言真的流传甚广。电视里有人讲， 文章里有人写。但像我刚刚说的，这完全是瞎扯。绝大部分情况下， 你的身体会提醒你该喝水了，因为你有一件奇妙的、神奇的、被大大低估的东西——你的肾。
Kidney s are the bean-shaped organs located to either side ofyour spine, right below your ribs. They're often thought ofas a filter or a waste-removal system, but that doesn't do thekidney s justice. Your body is an environment whereeverything, fluid and chemicals, needs to be in a delicatebalance. The kidneys do a lot of the heavy lifting when itcomes to this balance. Every day, blood in your body passesthrough the kidneys. What you eat, drink, the temperaturearound you, how much you exercise -- all of this affectswhat's going on with your body. Your kidneys, along withyour nervous system and various hormones, are constantlywatching many gauges and making adjustments about fluid,salt and levels of other substances in real time.
肾脏长得像豌豆， 位于你脊柱的两侧，肋骨下面一点点。它们经常被认为是过滤器或者垃圾清除系统，但这还不能完全描述肾脏的作用。你的身体是一个需要保持精妙平衡的环境，无论是体液还是化学物质。而肾脏在维持这种平衡的过程中发挥了重要作用。每天你身体里的血液都要经过肾脏。你每天吃的、喝的、你所处的环境温度、你的运动量，所有这些都会影响你的身体。你的肾脏， 连同你的神经系统和多种荷尔蒙一起， 时刻监测并调整你的体液、盐分和其他物质的水平， 都是实时的。
