Breathing is one of the most important pathways of interaction between the psychological and physiological processes of the body, and in psycho-oncology, it can be considered as one of the accessible mechanisms for modulating anxiety and autonomic arousal. Patients with cancer at different stages of diagnosis and treatment may experience anxiety, fear of the future, worry about the treatment process, pain, and physical complications, which can affect the activity of the autonomic nervous system.
Breathing regulation does not mean excessive control or forcing the body to breathe deeply, but rather involves creating a calm, orderly, and appropriate pattern of the person's situation. When the patient consciously slows and stabilizes his breathing rhythm, his attention shifts from threatening thoughts to the physical experience in the present moment. This process can reduce the intensity of rumination and anticipate negative consequences, and pave the way for a reduction in mental arousal. Therefore, breathing in the mind-body approach is not merely a physiological process, but rather serves as a bridge between physical experience and emotional regulation.
Autonomic nervous system arousal is an important component in the anxiety experience of cancer patients. Being in disease-related situations, such as waiting for test results, entering a treatment setting, receiving chemotherapy, or experiencing physical symptoms, can increase the body's autoimmune responses. In such a situation, a person may experience heart palpitations, sweating, muscle tension, altered breathing rhythms, or a feeling of physical pressure, and then interpret these symptoms as a sign of danger. Such an interpretation can increase anxiety and in turn increase automatic arousal, creating a reciprocal cycle between body and mind.
Regulating breathing can give a person time to reset their response to anxiety symptoms by interrupting this cycle. Focusing on inhalation and exhalation, observing the respiratory rhythm, and gradually slowing down the breathing rate can shift the patient's attention from a continuous assessment of the threat to a direct experience of the body. This shift in attention is important from a psychological perspective, as cancer anxiety is often associated with mental preoccupation with the future and trying to anticipate uncertain events. Restoring attention to the breathing process can help reduce cognitive engagement with these thoughts.
From a psycho-oncology perspective, the relationship between breathing and anxiety should be examined in the patient's individual and clinical setting. The type of cancer, the stage of the disease, the type of treatment, pain, fatigue, breathing problems, medications consumed, and psychological status can affect the experience of breathing and automatic arousal. Therefore, it is not possible to recommend a single breathing pattern for all patients. In patients with breathing problems or physical limitations, breathing exercises should be performed with caution and in harmony with the individual's medical conditions.
From the perspective of emotion regulation, mindful breathing can help increase the distance between the stimulus and the reaction. Instead of being immediately affected by fear or anxiety, the patient learns to observe their physical condition first and then develop a calmer response. This process can foster a sense of control and self-efficacy, which is very important in psychological adjustment to cancer. In fact, the goal of respiratory interventions is not to eliminate anxiety completely, but to increase the patient's ability to tolerate and regulate the arousal caused by the experience of illness.
The mind-body approach also emphasizes the principle that the experience of illness cannot be explained only at the level of the body or mind. Pain, fatigue, anxiety, sleep, breathing, and emotion are intertwined, and a change in one of these components can affect the other components. From this perspective, breathing regulation training can be used as a complementary tool alongside mindfulness, relaxation, cognitive-behavioral therapy, and other psychological interventions.
In clinical practice, breathing exercises are best short, simple, and repeatable so that the patient can apply them before treatment, while waiting at the treatment center, or when anxiety increases at home. Proper training is also important, as breathing too deeply or too quickly may cause some people to feel dizzy or uncomfortable. Therefore, the main emphasis should be on breathing comfortably, regularly, and without compulsion.
The relationship between regulating breathing, spontaneous arousal, and anxiety in cancer patients represents one of the important pathways of mind-body communication in psycho-oncology. Breathing can be considered as a visible indicator of the state of arousal and simultaneously as a tool for modulating it. Integrating breathing training with psychological and medical care can help the patient better understand their physical and emotional reactions, feel more in control over the experience of anxiety, and face the treatment process more adaptively. However, breathing regulation should be considered as a complementary and person-centered intervention, and if there are new physical symptoms or breathing problems, medical evaluation should precede the use of relaxation techniques.
