Your breath changes with your emotions. Stress, frustration and anxiety can make breathing faster, more irregular and more effortful. But the relationship also works in the opposite direction: changing how you breathe can influence the physiological state in which those emotions are experienced.
In this episode of The Breath Science Podcast, I break down how breathing interacts with the nervous system, carbon dioxide, heart rhythm, interoception, attention and physiological arousal.
Importantly, breathing is not a magic switch for turning stress or anxiety off. Different techniques affect different people in different ways, and sometimes focusing on the breath can actually make things worse.
We explore:
• Why stress and anxiety change the way you breathe
• How over-breathing and falling CO₂ can amplify uncomfortable sensations
• Why “take a deep breath” isn't always good advice
• How breathing influences heart rhythm and blood pressure regulation
• The role of interoception and how the brain interprets respiratory sensations
• Why breathing techniques can help organise attention during stressful moments
• When focusing on the breath may increase anxiety rather than reduce it
I also walk through three practical breathing techniques:
1. Extended exhalation breathing
A gentle way of reducing breathing pace and supporting a calmer physiological state.
2. Resonant or coherent breathing
Around six breaths per minute to create a smooth rhythm between breathing, heart rate and blood pressure regulation.
3. Box breathing
A structured breathing pattern that can be useful for focus and composure under pressure.
We also cover some of the most common mistakes people make, including breathing too deeply, slowing the breath too aggressively, forcing long exhalations and using breath control to avoid difficult emotions.
The goal isn't to find the “best” breathing technique.
It's to understand your current state, understand what different techniques actually do, and learn to select the right tool for the right moment.
