Don’t Dump Carbon Dioxide Too Fast!

CO2 is your friend (if not something much more intimate 😉)

FROM THE DAY YOU’RE BORN to the day you die, you’re a fountain of CO2…

When you get the itch to breathe, it’s your brain saying: “There’s too much CO2 on board, breathe so we can get it out.”

You’re brain is NOT saying: “We need more O2 in here!”

Although this “3 way relationship” may get a little awkward (i.e., practices to boost CO2 tolerance), you will be more resilient (physically & mentally) the more CO2 you can keep around…

“Performance on the CO2TT [CO2 Tolerance Test] was found negatively correlated with state anxiety. In other words, people with higher CO2TT results had lower in-the-moment anxiety, while those with lower CO2TT had higher in-the-moment anxiety.” — Findings from research done by the HHP Foundation

Breathing more than your metabolic need, dumps a TON of CO2 causing:

-Oxygen to stay bound to red blood cells — instead of being released into your brain, organs, and muscles)

-Blood flow to decrease (CO2 is a vasodilator)

-Blood PH and alkalinity to increase.
