Breathing Exercise 呼吸练习
Breathing for the Afternoon Energy Slump 下午精力低谷呼吸练习
The post-lunch dip is a circadian inevitability, but inhale-dominant breathing (6-0-2) can restore alertness within 3 minutes — without coffee or sugar. A natural, effective desk-side reset.
午后精力低谷是昼夜节律的必然现象，但以吸气为主的呼吸（6-0-2）可在3分钟内恢复警觉性——无需咖啡或糖分。一种自然有效的桌边重置方法。

How to Practice
- At the first sign of afternoon fatigue, step away from your screen and sit up straight in your chair.
- Open a window or step outside briefly to get fresh air if possible.
- Inhale deeply through your nose for 6 seconds, filling from the bottom of your lungs upward.
- Exhale sharply through your mouth in 2 seconds, pushing air out forcefully.
- Repeat 10 times, keeping your posture upright. Notice alertness returning by the fifth cycle.
