喝咖啡应该避开几个时间段
Many of us wake up with one thing on our minds- coffee! Or at least, some form of drink that contains caffeine to begin our study. But what if I told you that you may drink your coffee incorrectly this entire of time?
我们许多人醒来时脑子里就想着一件事：喝咖啡！或者至少某种含有咖啡因的饮料来开始工作和学习。但是，如果我告诉你，一直以来，你喝咖啡的方式是错的，会怎么样呢？
We all have an internal biological clock called (Circadian rhythm), which regulates many processes inside our bodies, including how we are to sleep during the day. Also this part control the release of a hormone called (cortisol), which often refers to the stress hormone because it is secreted at high levels through the body in response to the so-called theory of "hit-and-run".Cortisol secretion is also associated with the level of your waking during the day. And the highest peak cortisol levels get between 8 and 9:00 am. This means that your body has a natural mechanism to wake you up.
我们都有一个内在的生物钟，叫做昼夜节律，调控我们身体内部许多进程，包括一天之内何时想要睡觉或醒来。这个过程也控制着一种叫做皮质醇的荷尔蒙的释放。这种荷尔蒙通常被叫做压力荷尔蒙，因为面临很大的压力时，体内的皮质醇就会积累到很高的水平。皮质醇的分泌还和你清醒的水平有关。早上8:00至9:00，皮质醇达到最高水平。这意味着身体有一个自然机制让你醒来。
And while you might think that caffeine can complete this mechanism, scientists have already found that consumption of coffee or energy drinks during peak cortisol production greatly reduces the caffeine effect and increases the strength to resist the caffeine in the long run. Overall, this means that you get less of bangs, and you need larger amounts in the future. We have analyzed addiction and resistance of caffeine in one of the last episodes, you can watch them from here.
你或许认为咖啡因能够打破这一机制，科学家发现，在皮质醇高峰期喝咖啡或能量饮料会大大降低咖啡因的效果，增强身体对咖啡因的耐性。总的来说，这意味着清醒作用效果降低，你需要喝更多的咖啡才能保持清醒。我们在最新的视频中分析了咖啡因上瘾和耐性，你也可以观看一下。
For this reason, drinking coffee after 9:00 am cortisol is probably the best. Scientists found a few other times when cortisol is also at its peak: between noon and one o'clock noon, and 5:30 and 6:30 pm. And that means that the best time to drink your coffee be outside of these times.
由于这个原因，早上9:00点以后喝咖啡的效果可能更好。科学家发现皮质醇水平达到高峰的其他几个时间：中午和下午1:00之间，下午5:30和6:30之间。这说明喝咖啡的最佳时间应该避开这些时段。
These cortisol - and bio-hour rhythm generally - it is more stongly organized by sunlight, that is not to your sleep schedule a significant impact.
皮质醇和生物钟总体来说通过阳光得到调整，这对你的睡眠安排来说有着非常重大的影响。
So what if I wake up extreamly early, or really late? Should you drink coffee in the case?
那么，如果我醒来得太早，或者太晚呢？这种情况下建议喝咖啡吗？
Well, scientists have acctually found that cortisol levels increase immediately after sleep by 50%, regardless of the time. Scientists says, wait at least an hour before you pick up your coffee, until it becomes your body maybe optimally ready to go.
科学家实际上发现，醒来后皮质醇的水平立即上升50%，无论是什么时间。科学家说，等待一小时再喝咖啡，让你的身体根据光线做好调整。
