A cup of freshly ground coffee is what it takes to get some people moving in the morning.
清晨起来，一杯新鲜的研磨咖啡可以让人精力充沛。
But, according to a study, it may be the aroma rather than the coffee itself that does the trick.
但一项最新的研究表明，这种功效可能是咖啡的香气而不是咖啡本身产生的。
Researchers believe that the aroma of roasted coffee beans can soothe frayed nerves - and that just the whiff could be enough to reverse the effects of a poor night's sleep on the brain.
研究人员相信，烘培咖啡豆的香气可以安抚紧张的神经-而且只是一点点香气就可以缓解整夜失眠对大脑造成的影响。
Aroma: Just smelling coffee can help cure tiredness better than drinking a cup
香气: 仅仅闻咖啡比喝一杯咖啡更能帮助缓解疲劳。
