导读:喝咖啡不一定能提神还不利健康，研究发现爬楼梯更利于提神。
Forget your morning coffee - spend 10 minutes walking up and down some stairs instead.
早上别喝咖啡提神了，花十分钟时间上下走楼梯吧。
It sounds like a nightmare. But according to new research, that little bout of exercise will do far more for your energy levels than if you were to take the elevator while slurping on a soda or a cappuccino - and saves you some money.
这个建议听起来似乎很糟糕，但是据最新的一个调查所示，这样少量的锻炼比喝着苏打水或卡布奇诺坐电梯更有助于身体能量的提升，而且还省钱。
The study aimed to simulate the hurdles faced in a typical office setting, where workers spend hours sitting and staring at computer screens and don’t have time for a longer bout of exercise during the day.
这项研究的目的是模仿典型的办公室环境中的障碍，在这里员工们长时间坐着盯着电脑屏幕，一天下来没有时间做长时间的锻炼。
For the study, participants on separate days either ingested capsules containing caffeine or a placebo, or spent 10 minutes walking up and down stairs - about 30 floors total - at a low-intensity pace.
在调查中，参与者每天分别服用含咖啡因或是安慰剂的胶囊，或者以较低的速度爬10分钟楼梯-总计大约30层。
To test the effects of caffeine versus the exercise, each group took some verbal and computer-based tests to gauge how well they performed certain cognitive tasks.
为了检测咖啡因和锻炼带来的影响有什么区别，每组参与者会做一些口头测试和电脑测试来估测他们在一些特定的认知测试中的表现。
Neither caffeine nor exercise caused large improvements in attention or memory, but stair walking was associated with a small increase in motivation for work.
咖啡因和锻炼都不会带来很大的注意力和记忆上的提高，但是走楼梯会带来一点工作积极性的提高。
There is still much research to be done on the specific benefits of exercising on the stairs, especially for just 10 minutes. But even a brief bout of stair walking can enhance feelings of energy without reducing cognitive function.
要研究走楼梯，尤其是走十分钟楼梯带来的具体好处还需要做更多的调查，但是即便是短时间的走楼梯也能在不降认知能力的前提下提升你的精力。
You may not have time to go for a swim, but you might have 10 minutes to walk up and down the stairs.
你可能没时间去游泳，但是可能会有十分钟的时间去爬楼梯。
