Apnea Test
How does this work?
- Sit with your back straight
- Watch your breathing for 1 minute without trying to change it
- Then, after exhalation without forcing or contracting your abs, hold your breath by necessarily pinching your nose
- At the same time start the stopwatch below to measure and record your apnea time
- Stop at the first sign of lack of oxygen (which corresponds precisely to the first spasm of the diaphragm, the muscle of your breathing)
- Take the next test (you will then find out your current stress level)
