Breathing Exercise 呼吸练习
Breathing for Middle-of-Night Waking 夜间觉醒呼吸练习
Waking at 2–4 am often signals cortisol rising prematurely. The 4-7-8 technique used in darkness, without checking the clock, counteracts this arousal and helps most people return to sleep in under 20 minutes.
凌晨2–4点醒来通常是皮质醇过早升高的信号。在黑暗中不看时钟地使用4-7-8技法，能对抗这种唤醒，帮助大多数人在20分钟内重新入睡。
