It's known to make you feel more awake, and now it seems that coffee may also improve your maths skills. And the best news is that you don't even need to drink it to see the improvements - you just need to smell it. Coffee is actually very healthy. It is loaded with antioxidants and beneficial nutrients¹ that can improve your health. The studies show that coffee drinkers have a much lower risk of several serious diseases.

众所周知，咖啡会让你感觉更清醒。现在看来，咖啡或能提高你的数学能力。最棒的是：你甚至无需喝咖啡就能看到效果--只要闻一闻就行。咖啡实则非常有利身体健康。它含有多种抗氧化剂和有益营养成分，促进人体健康。研究表明：咖啡饮用者患各种严重疾病的风险更低。

A new study by researchers from Stevens Institute of Technology has revealed that the scent² of coffee may help your maths skills. Professor Adriana Madzharov, who led the study, said: "It's not just that the coffee-like scent helped people perform better on analytical³ tasks, which was already interesting. But they also thought they would do better, and we demonstrated that this expectation was at least partly responsible for their improved performance."

史蒂文斯理工学院的研究人员开展的一项新研究揭示：咖啡的香味或有助于提高数学能力。Adriana Madzharov教授牵头这项研究，她说："咖啡般的香味不仅能提高人们的分析能力，这本身就很有意思。而且人们还觉得咖啡香能带来更多益处，我们已证明，表现力提高至少部分是因为咖啡香所致。"

In the study, 100 business students took a 10-question algebra⁴ test. Half the group took the test in the presence of a coffee-like scent, while the other half took the test in an unscented room. The results revealed that the group in the coffee-smelling room scored significantly higher on the test than those in the unscented room.

在这项研究中，100位商学院学生做了10道代数题。一半的人是在咖啡香味的环境中做的测试题，另一半是在没有咖啡香味的房间中做的题。结果表明：在咖啡香味环境中做题的学生的得分明显高于在没有咖啡香味环境中做题的学生。

In a follow-up study, the researchers quizzed 200 new participants on their beliefs about various scents⁵ and their effects on human performance. Their answers revealed that they believed they would feel more alert in the presence of a coffee scent. This suggests that their expectations about performance may have influenced their improved skills.

在后续研究中，研究员对200名其他受试者做了测试，询问在他们心中各种气味及这些气味对人们表现力的影响是何想法。他们的答案表明：闻到咖啡香，他们就会更清醒。这表明他们对表现力的期望或影响他们能力的提升。

The researchers believe that the findings could have major implications in the real world. Professor Madzharov added: "Olfaction is one of our most powerful senses. Employers, architects, building developers, retail⁶ space managers and others, can use subtle scents to help shape employees' or occupants' experience with their environment. It's an area of great interest and potential."

研究员认为这些研究结果或对现实世界产生重大影响，Madzharov教授补充说："嗅觉是我们最强大的感官之一。雇主、建筑师、建筑开发商、零售空间经理和其他人能利用微妙的气味来塑造员工或居住者对环境的体验。这是个非常有意思、有潜力的领域。"
