## Breathing Deep: How Breathwork’s CO2 Drop May Unlock Altered States of Consciousness
Breathwork, the practice of consciously controlling one’s breathing, has gained immense popularity for its purported ability to reduce stress, improve focus, and even induce altered states of consciousness. While anecdotal evidence abounds, scientific understanding of the mechanisms behind these effects is still developing. A new study published in *Nature*, highlighted in a recent discussion, sheds light on a potential key player: decreased carbon dioxide (CO2) levels in the body.
The *Nature* article, titled “Decreased CO2 during breathwork: emergence of altered states of consciousness,” examines the link between specific breathwork techniques and the resulting physiological changes, particularly focusing on the drop in CO2. It postulates that this decrease, induced by practices like hyperventilation often found in certain breathwork modalities, is a significant factor in triggering altered states of awareness.
So, how does lowered CO2 contribute to these transformative experiences? The answer likely involves a complex interplay of physiological processes. Lowered CO2 levels can lead to cerebral vasoconstriction, meaning blood vessels in the brain constrict. This reduced blood flow can affect brain activity and potentially contribute to feelings of lightheadedness, euphoria, and detachment from reality – hallmarks of altered states.
Furthermore, the study suggests that the decrease in CO2 may impact the body’s pH balance, leading to respiratory alkalosis. This shift can influence neuronal excitability, making the brain more susceptible to unusual patterns of activity. This increased excitability might explain why breathwork practitioners sometimes report vivid hallucinations, intense emotional releases, and profound shifts in perspective.
While the *Nature* study focuses specifically on the role of CO2, it’s crucial to understand that breathwork’s effects are likely multifactorial. Other elements, such as activation of the parasympathetic nervous system (the “rest and digest” response), increased oxygen intake, and focused attention, undoubtedly contribute to the overall experience.
The findings of this research are significant because they offer a more concrete, physiological explanation for the often-subjective claims surrounding breathwork. It provides a starting point for further investigation into the specific breathwork techniques that are most effective for inducing desired states and, more importantly, for understanding the safety parameters associated with these practices.
Ultimately, the *Nature* study strengthens the scientific foundation for breathwork, moving it beyond the realm of purely anecdotal evidence. By highlighting the crucial role of decreased CO2 levels, it opens the door for more targeted research and a deeper understanding of the powerful connection between our breath and our consciousness. As research continues, we can expect a more nuanced and scientifically informed approach to utilizing breathwork for therapeutic and personal growth purposes.
