How Long Does Alcohol Stay in Your System? 酒精会在体内停留多久? We’ve all known not to drink and drive. But how long does alcohol stay in your system? Should you worry about driving, say, the morning after a night out with friends? We asked an expert to explain just how long it takes your body to rid itself of alcohol. 喝酒不开车，这个道理我们都懂。但酒精会在体内停留多久呢？如果前一晚和朋友出去喝酒，第二天能不能开车呢？专家给我们答疑——酒精在人体内多长时间可以排干净。 For starters, we’ll give you a refresher on what happens to your body when you drink. You’ve probably heard that alcohol use—depending on how much you drink—can harm your liver. But you may not have been warned about just how much stress you put on this vital blood-filtering organ after even just a few hours of partying. 首先，我们先聊一聊喝酒时身体发生的变化。你也许听说过，喝酒伤肝——取决于喝多少。但也许并没有人告诉你，仅狂欢几小时就会对这一重要的血液过滤器官施加极大压力。 “When you get alcohol in your blood, it passes through the liver, and the liver breaks it down,” explains George Koob, PhD, director of the National Institute on Alcohol Abuse and Alcoholism, a division of the NIH. “人体血液含酒精时，酒精会流过肝脏，被肝脏分解，”美国国家酒精滥用和酒精中毒研究（美国国立卫生研究院的下属部门）的所长乔治·科布（George Koob）博士解释道。 |
