exhalation time

基本解释

Exhalation % takes twice as long as inhalation. The absolute time you spend on each phase is not important; the ratio of 4-7-8 is important.
呼气的时间要是吸气的两倍。每次吸呼过程的时间并不重要，重点是要保持4-7-8的比例系数。。
Stay for 30 seconds to 1 minute, then release with an exhalation, return to the starting position, and repeat to the left for the same length of time.
保持30秒到1分钟，然后呼气放松，回到开始的姿势，转向左重复同样时间。

The Complete Relaxation can be done in a broad range of time frames. To learn to do this as slow as the length of time for one exhalation down, and one inhalation up, is very useful.
完全呼吸可以在很广泛的时间范围内进行，学着做这个象一轮呼气、吸气的时间长度一样缓慢，是非常有益的。
