The way you breathe offers clear clues about which state your nervous system is in:

Dorsal Vagal (Collapse/Shutdown): In a state of extreme overwhelm, your body may enter a collapse response. Here, your breath becomes very slow and shallow, but still lacks the depth and rhythm of a ventral state. Your body minimizes movement, and diaphragmatic breathing is still restricted as your system remains in a protective, albeit immobilized, stance.

Ventral Vagal (Rest & Digest): In this state of safety and connection, your breath is typically slow, rhythmic, and diaphragmatic. You’ll notice your belly gently rising and falling, indicating that your core muscles are relaxed and not engaged in protection. This allows for full, uninhibited breathing.

Sympathetic (Fight or Flight): When your system perceives a threat, muscles tense to protect vital organs. Consequently, your breath becomes shallower and faster, primarily occurring in your chest. Access to deep, rhythmic diaphragmatic breathing is limited as your body prepares for action.

Understanding the physiological impact of inhalation and exhalation provides a powerful insight into how breathwork can regulate your nervous system:

• Inhale: Each inhale causes your heart rate and blood pressure to rise. This is because as your lungs expand, blood needs extra force to travel further and reach your brain and extremities. This sympathetic activation is essential for energizing the body.
• Exhale: Conversely, each exhale causes your heart rate and blood pressure to drop. This is a parasympathetic response, signaling your body to relax and conserve energy.

This dynamic explains why:

• Relaxation-focused breath practices (aimed at the ventral state) often emphasize longer exhales than inhales. By extending the exhale, you actively engage the parasympathetic nervous system, promoting calm. Think of the common advice to “relax” with a long, drawn-out sigh – we intuitively know this calms us.
• Energizing breath practices (aimed at sympathetic activation) tend to feature stronger inhales with less emphasis on the exhale.

While specific counting might be involved in certain practices, the core principle remains: extending your exhales is a primary way to activate the parasympathetic nervous system and foster relaxation.

Learning to recognize your breath patterns is a crucial step in nervous system regulation. It serves as a highly reliable early indicator of your nervous system’s state. For instance, if you walk into a room and suddenly notice your breath becoming faster and shallower, it’s a strong signal that your system is interpreting something in that environment as potentially unsafe.

This awareness allows for curiosity: “What is my system reacting to here?” Instead of being caught in an unconscious stress response, you gain a data point. For example, a basketball player stepping up for a free throw might notice their breath becoming shallow due to performance tension. By consciously extending their exhales, they can actively signal their body to calm down, improving focus and performance.

By becoming attuned to your breath and learning various breath practices, you transition from being a passive recipient of your nervous system’s reactions to an active operator of your internal state. This is the ultimate goal of nervous system regulation.

It’s common for individuals who have experienced prolonged periods in defensive states to develop dysfunctional breathing patterns, often struggling with diaphragmatic breathing. Trying to breathe deeply and fully, especially into your belly, can feel challenging, even distressing, at first. Your system might resist, interpreting this intentional shift out of a defensive posture as unsafe, creating a sense of dissonance.

This initial discomfort can be frustrating, especially when a practice seems superficially simple. It’s vital to recognize that despite appearances, breathwork is truly hard work that can yield profound benefits. Be gentle with yourself. Every clunky, awkward breath is a step towards rewiring deeply ingrained physiological patterns. The journey may not always be smooth, but the ability to actively influence your nervous system through your breath is an incredibly empowering reward.
