最佳喝咖啡时间：上午10:30

科学家研究发现，一天中喝咖啡的最佳时间大概是在上午9:30到11:30之间。这是由咖啡因和皮质醇相互作用的方式决定的。“皮质醇”帮助调节身体内部的生物钟，并且让人更加警觉。

皮质醇的水平在刚起床时是很高的，并且一直持续一个小时之久，在上午8点到9点达到最高。在皮质醇水平高的时候喝咖啡，会让人们对其中的咖啡因产生耐受性，意味着人们需要在早上再喝一杯咖啡才能达到相同的效果。

其他科学家们发现，在下午喝咖啡能帮助消化午餐吃得过多的食物。最近的调查表明，科学家是所有职业中喝咖啡最多的人，其次是市场营销和公关人士。

The best time to drink a cup of coffee to get your daily hit of caffeine is between 9.30am and 11.30am, according to neuroscientists.

It may seem that a cup of strong coffee first thing in the morning is the best way to get yourself going, but it in fact waiting until later may be better.

Scientists have worked out that the best time to get a daily hit of caffeine is on average between 9.30am and 11.30am.

This is due to the way caffeine interacts with a key hormone – called cortisol – which helps to regulate the body’s own internal clock and promotes alertness.

Cortisol levels are naturally high shortly after waking up and can remain high for up to an hour afterwards – with the average peak being between 8am and 9am.
