A little booze before bedtime might help you fall asleep faster. But various studies show that alcohol is anathema for restorative sleep. A new review paper describes just how detrimental a few drinks can be.
睡前一杯小酒能帮你更快地进入梦乡 。但各类研究表明酒精是对恢复性睡眠的“诅咒” 。一份新的综述论文阐述了睡前饮酒的种种不利 。
The researchers pored over 20 studies conducted in controlled lab settings. They found a clear trend that just about any amount of alcohol alters sleep. And the effects are usually bigger with more drinks.

Perhaps the most potent finding is that just a single dose of alcohol in the late evening can zap the efficacy of your z's. The paper is in the journal Alcoholism: Clinical and Experimental Research.
