The CO2 Tolerance Test is a simple yet effective way to assess your stress tolerance and gain insights into your breathing mechanics. In this post, we will guide you through the process of performing the CO2 Tolerance Test and interpreting the results.


What is the CO2 Tolerance Test?


The CO2 Tolerance Test is a measure of your ability to handle elevated levels of carbon dioxide in your body. By evaluating how long you can comfortably hold your breath, the test provides valuable information about your breathing efficiency and stress resilience.



How to Perform the CO2 Tolerance Test:

Follow these steps to perform the CO2 Tolerance Test accurately:

  1. Find a quiet and comfortable space: Choose a peaceful environment where you can sit or lie down without any distractions. Have a timer ready nearby.

  2. Take three normal breaths: Breathe naturally for a few moments to establish a baseline.

  3. Inhale deeply on the fourth breath: Inhale deeply through your nose, filling your lungs with air as much as possible.

  4. Start a timer and exhale as slowly as you can: Exhale as slowly as you can. This can be through your nose or mouth. I find through pursed lips is most effective. Aim for a controlled and steady flow of breath.

  5. Time your exhale: Start a timer as soon as you begin exhaling.

  6. Record the time: Note the duration of your exhale in seconds.

  7. Repeat the test: Repeat steps 2 to 6 two more times to obtain an average breath exhale time.


How to Interpret your Results:

Once you have completed the CO2 Tolerance Test, you can interpret the results as follows:


Exhale Time 60+ seconds:

  • If you can comfortably exhale for 60 seconds or more, it indicates excellent stress management skills and a high level of CO2 tolerance.

Exhale Time 45 seconds:

  • A exhale time of around 45 seconds suggests a moderate level of stress management ability. While you can handle everyday stress well, additional pressures might pose a challenge.

Exhale Time 30 seconds:

  • A exhale time of approximately 30 seconds indicates that higher stress days could be more challenging for you. It may be beneficial to explore stress management techniques and breathing exercises to improve your resilience.

Exhale Time 20 seconds or less:

  • If you struggle to exhale for 20 seconds or less, it may indicate that your breathing mechanics and CO2 tolerance need attention. Focus on enhancing your breath control and seeking guidance from a breathing specialist if needed.


The CO2 Tolerance Test provides valuable insights into your stress tolerance and breathing mechanics.


By performing this simple test, you can gauge your ability to handle elevated carbon dioxide levels and gain a better understanding of your stress management skills. Use the results as a starting point to explore breathing techniques, stress reduction strategies, and seek professional guidance if necessary. Remember, practicing breath awareness and enhancing your CO2 tolerance can contribute to improved overall well-being and resilience.
