For many of us, it is the rocket fuel that gets us going first thing in the morning.
对我们许多人来说,早起第一件事就喝咖啡则如同火箭燃料一般,能让我们清醒起来动起来。
But one expert has argued that to get the maximum effect of caffeine, it's better to hold on a few hours - because coffee is most effective if consumed between 9.30am and 11.30am.
但是有专家认为,要想获得咖啡因的最佳效果还得再等上些许时间。因为在上午9:30-11:30这个时间段喝咖啡才是最有效的。
Steven Miller, a neuroscientist from the Uniformed Services University of the Health Sciences in Maryland, says it is best to drink coffee when the body’s levels of the hormone cortisol are low because caffeine interacts with the hormone.
马里兰州国防医科大学的神经学家史蒂芬·米勒认为,最好在身体中的荷尔蒙皮质醇水平偏低时喝咖啡,因为这时咖啡因和荷尔蒙相互作用。
He explained that people who drink coffee when their cortisol levels are high – namely, between 8am and 9am – develop a tolerance to caffeine, meaning it becomes less effective.
他解释道,当人们在上午8-9点中皮质醇水平较高时喝咖啡,身体对咖啡因有耐受性,并不是很有效。
Cortisol controls the body clock and causes people to feel wide awake, The Telegraph reports. The body’s levels of the hormone are usually high just after a person wakes up but start to fall about an hour afterwards.
