Fruit
Fruit is an excellent food for an energy-lift that won’t make you crash later.
水果
吃水果既能补充能量，又不会因为吃的太饱而产生困意。

Water
Dehydration is a big cause of tiredness and if your eyes are showing signs of lethargy splash some cool water on your face.
水
脱水是疲倦的一大起因。如果你的眼皮开始打架，给脸上泼点冷水吧。

Air conditioning
Cold air keeps your body’s heat-regulating system ticking over, which might use up energy in hindsight, but at least you’ll shiver yourself awake.
空调
冷空气让身体的温度调节系统加快运行，这样虽然会耗费能量，但至少你会因为发抖而清醒。

Light exercise
Walking or running up the stairs will get your heart rate up. It gets your blood pumping to your head more quickly.
少量运动
散散步，爬爬楼梯会让你的心脏加快跳动。这让血液更快到达大脑。

Fresh air
Sitting in a warm office in front of a roaring computer screen surrounded by the gentle prattle of idiotic workmates is enough to send anyone to sleep. Go outside and breathe in some of the fresh air for a few minutes; just try not to give up and go home whilst you’re out there.
新鲜空气
在温暖的办公室里对着呼呼作响的电脑屏幕，听着周围同事的窃窃私语，谁都会睡着。出去呼吸一下新鲜空气，只要别改道溜回家就行。
