Counterintuitive Responses: Paradoxical Reactivity

Introduction

Biofeedback is a psychophysiological technique that allows individuals to gain awareness and control over their involuntary body functions, such as breathing, heart rate, muscle tension and galvanic skin response. One of the most intriguing and complex phenomena observed during biofeedback is paradoxical reactivity, i.e. an unexpected or counterintuitive response during training. For example, in the presence of optimal respiratory coherence, an increase in physiological arousal can be observed, which runs counter to the intended goal of relaxation or emotional regulation.

Respiratory coherence and biofeedback

Respiratory coherence is an optimal state in which breathing rate is synchronised with heart rate variability (HRV). It is commonly associated with benefits such as:

• Reduced stress.

• Improved emotional regulation.

• Increased psychological and physiological resilience.

Respiratory biofeedback aims to achieve respiratory coherence and induce a state of parasympathetic relaxation. In some cases, however, a paradoxical response occurs: while objective markers indicate respiratory coherence, other physiological parameters—such as skin conductance (arousal)—increase, indicating activation rather than relaxation.

Causes of paradoxical reactivity

Paradoxical reactivity can be attributed to a combination of psychophysiological, psychological and methodological factors. Below, we will explore the main causes.

1. Cognitive overload

• Description: During biofeedback, the user may focus excessively on regulating their breathing or following visual or auditory cues, creating cognitive overload.

• Result: This hyperfocus can activate the sympathetic nervous system and increase arousal even when respiratory coherence is evident.

2. Residual emotional dysregulation

• Description: If the subject enters training with an unregulated emotional state (e.g. anxiety or accumulated stress), breathing coherence may not be enough to induce complete relaxation.

• Result: The increase in arousal may reflect an internal conflict between physiological relaxation and unprocessed emotional states.

3. Individual sensitisation responses

• Description: Some individuals show greater sensitivity to internal stimuli (e.g. perception of heartbeat or breathing). This hypersensitivity can generate an alarm response or an increase in arousal.

• Result: Biofeedback can amplify these sensations, creating discomfort and activation instead of calm.

4. Role of neurobiology

• Description: The autonomic nervous system (ANS) varies considerably between individuals in its ability to adapt. Some people may have persistent sympathetic dominance or difficulty “switching off” the alarm system.

• Result: Even under conditions of respiratory coherence, sympathetic dominance can cause an increase in arousal.

5. Methodological errors

• Description: The equipment used for biofeedback may not be fully synchronised or accurate, leading to discrepancies in the data collected.

• Result: Respiratory-coherence parameters may not fully reflect the person’s psychophysiological state.

Psychophysiological dynamics of paradoxical reactivity

Paradoxical reactivity involves a complex interaction between physiological and psychological systems. Some of the underlying mechanisms include:

1. Positive feedback and arousal

Excessive attention to physiological indicators can create a positive feedback loop in which the person feels under pressure to achieve a particular result, paradoxically increasing arousal.

2. Activation of the sympathetic system

An attempt to regulate involuntary functions such as breathing may be perceived as a threat or a demanding task, activating the sympathetic nervous system.

3. Cognitive-emotional conflicts

If the person experiences an internal conflict (e.g. a desire to relax versus performance anxiety), this may create psychological dissonance and increase arousal.

Strategies to mitigate paradoxical reactivity

To address and reduce paradoxical reactivity, it is essential to take an integrated approach. Here are some strategies:

1. Preparation of the subject

• Educate the subject about possible paradoxical phenomena.

• Encourage an attitude of acceptance and non-judgement towards their physiological responses.

2. Gradual regulation

• Introduce biofeedback progressively, with short and simple sessions to avoid overload.

• Monitor arousal and adjust the difficulty of the task.

3. Complementary techniques

• Integrate biofeedback with other emotional-regulation techniques, such as mindfulness or progressive muscle relaxation.

• Promote stress management through grounding techniques.

4. Adaptation of equipment

• Use highly sensitive and synchronized biofeedback tools to ensure data accuracy.

• Use a multimodal approach that measures several parameters (breathing, HRV and skin conductance) to provide a holistic view.

5. Expert supervision

• Make sure that the biofeedback training is supervised by an expert, who can intervene promptly in case of paradoxical responses.

Conclusions

Paradoxical reactivity is a challenge in the context of biofeedback, but also offers an opportunity to deepen the understanding of psychophysiological dynamics. This phenomenon emphasizes the importance of a personalised and flexible approach to biofeedback, that takes into account individual differences and the complexity of mind-body systems.

A focus on the preparation of the subject, the use of appropriate tools and the integration of complementary techniques can significantly reduce the frequency and impact of these counterintuitive responses, making biofeedback an even more effective and accessible intervention.
