早起的绝招

Calculate Your Ideal Bedtime

计算出你的理想睡觉时间

The easiest way to wake up earlier in the morning is to get enough sleep.

早起最简单的方法就是有充足的睡眠。

But that number can be drastically different for everyone.

但是这个数字对于每个人来说可能会大不相同。

Here's how to figure out your sleep needs: For a week, track the number of hours you sleep, including weekends.

以下是如何找出你的睡眠需求：统计好一周（包括周末）之内的睡眠总时间。

Divide that number by seven to calculate

your nightly need. Think about a time you've been on vacation or of a night you felt particularly rested — how much sleep did you get?

将这个数字除以七，计算出你每晚的需要。想想你曾经在度假时的晚上，或者你感到特别的休息时，你睡了多久？

Once you have that number, count backwards from the time you want to get up and plan to go to bed at that new hour.

一旦你计算出这个数字，从你想起床的时间开始倒数，并在新计划好的时间上床睡觉。
