Many people unknowingly over-breathe, especially when they feel anxious or stressed. We’re often told to “take a big breath” to calm down, but for many nervous systems, that advice can actually do the opposite.
One of the most important things I work on with my Functional Breathing clients is how they breathe, moment to moment, day and night.
That means looking at things like how fast they’re breathing, whether they’re breathing through their nose or mouth during the day and during sleep, and whether their breathing is light & diaphragmatic, or shallow & chest-based.
Chronic over-breathing lowers carbon dioxide levels in the body. CO₂ isn’t just a waste gas, it’s essential for releasing oxygen from the blood into the brain and tissues. When CO₂ drops too low, blood vessels constrict, oxygen delivery is reduced, and the brain can become overstimulated. This can show up as a racing mind, heightened anxiety, and constant mental chatter.
This is why a core focus of my work is restoring slow, quiet, nasal breathing. When breathing becomes gentler and more efficient, CO₂ levels normalize, oxygen delivery improves, and the nervous system receives a powerful signal of safety.
Calm doesn’t come from breathing more.
Very often, it comes from breathing less, but better.
