Breathwork is gaining increasing popularity in France. Presented as a powerful method for releasing emotions, reducing stress and influencing the mind, it is attracting more and more practitioners... often without a framework, without knowledge of the nervous system, and without appropriate guidance.
However, breathing is a direct control over human physiology. When used incorrectly, it can cause undesirable effects that are sometimes poorly understood or even worrisome for the person practicing it.
The objective of this article is to clarify an essential point: Breathing exercises are not just a relaxation technique; they are a tool that directly affects the autonomic nervous system.
Breathing is not an insignificant act. Breathing directly influences:
the heart rate
Blood pressure
the CO₂ and O₂ levels in the blood
the activation of the sympathetic (stress) or parasympathetic (calming) system
Some forms of breathwork deliberately use breathing rhythms that profoundly alter this balance. This can lead to:
vertigo sensations
tremors
muscle tension
intense emotional surge
altered states of consciousness
These reactions are physiological. They are neither mystical nor psychological. They are directly related to the impact of breathing on the chemistry of the blood and the nervous system.
Without understanding these mechanisms, some sessions can become uncomfortable, or even anxiety-inducing for the practitioner.
The most frequent risks observed during unsupervised sessions are:
Breathing too quickly and for too long can greatly lower the CO₂ level, causing:
significant dizziness
muscle spasms
sense of loss of control
Breathing exercises can bring up memories or emotional burdens. Without a safe framework, this can destabilize the person.
Many practitioners interpret normal bodily reactions as unusual phenomena, which can generate fear or misunderstanding.
A professional session is not just about “breathing hard for 30 minutes”.
It includes:
a clear explanation of the expected effects
a progression in breathing intensity
phases of recovery and integration
a reassuring verbal framework
constant monitoring of the body's reactions
The facilitator’s role is to allow the practitioner to understand what they are experiencing, so that the experience is safe and beneficial.
Breathing exercises are an extremely powerful tool when practiced in the right context. They can promote:
stress regulation
emotional liberation
calming the mind
a better bodily connection
But this requires precise pedagogy and knowledge of the functioning of the nervous system.
As with any practice that directly affects physiology, The quality of the supervision makes all the difference.
Before participating in a session, it is useful to check:
if the facilitator explains the physiological effects of breathing
if it provides for recovery periods
if the session is progressive and structured
if a reassuring framework is established from the outset
Breathing exercises are not a dangerous practice.
But, like any powerful tool, it requires understanding, structure, and support.
