春眠不觉晓，然而许多现代人却饱受失眠的困扰，夜夜辗转反侧。睡眠专家指出，其实人们可以“训练”自己的大脑来入睡。

1. Make a schedule, and stick to it

每天在固定时间起床和上床

Melatonin is a hormone1 produced by the body to regulate when you get sleepy and when you wake up. As night approaches, levels of melatonin rise, becoming a signal to the body that it's time for bed. Production of melatonin is stopped by light -- so levels naturally fall as daylight approaches, getting you ready to greet the day.

褪黑素是身体分泌的一种激素，你什么时候感到困，什么时候醒来，都靠这种激素来调节。随着黑夜降临，褪黑素的水平就会升高，暗示身体该睡觉了。光线会阻止身体分泌褪黑素，所以白天来临时褪黑素水平就会下降，让你准备好迎接新的一天。

To work properly, the release of this hormone needs to occur at regular times, said clinical psychologist and sleep expert Michael Grandner. So if your bedtime and wake up time change from day to day or on weekends, he said, your sleep rhythms aren't predictable and the body doesn't know how to respond.

临床心理学家、睡眠专家迈克尔·格兰德纳指出，为了让身体正常分泌褪黑素，你必须规律作息。如果你的上床和起床时间每天都不一样或者一到周末就改变，身体就无法预测你的睡眠节奏，也就不知道如何作出反应。
