Diaphragmatic Breathing exercises helps manage PTSD (Post traumatic stress disorder). PTSD is a type of anxiety disorder that develops in some people after exposure to extremely traumatic events, such as combat, crime, domestic violence, an accident, or a natural disaster.
People with PTSD suffer from intrusive memories, social and interpersonal problems, heightened anxiety and difficulty with emotional regulation.
Conventional treatment for PTSD includes medications (anti-depressants) and psychotherapy. However, many people don’t do well with the standard treatment and might experience residual effects of the disorder.
Respiration and emotions are tightly coupled processes with bidirectional influences. Breathing interventions have been seen to boost emotional regulatory processes in persons with PTSD.
Breathing interventions can reduce traumatic emotions
According to emotional processing theory, the relationship between a stimulus and its fear response can be disrupted by habituation caused by exposure. Breathing interventions can decouple the stimulus (intrusive memories) and the fear response and thus reduce the traumatic feelings.
Breathing exercises shows improvement in hyper arousal symptoms
The growing body of data demonstrates the positive effect of breathing interventions on hyperarousal and re-experiencing symptoms. These findings are promising as Hyperarousal state yields the strongest influence on individual’s health than other symptoms of PTSD.
Breathing interventions normalises the imbalance in autonomic nervous system
Studies have shown that PTSD symptoms are induced by imbalances in the ANS. Voluntary slow deep breathing functionally resets the autonomic nervous system through many mechanisms:
First, slow deep breathing increases O2 delivery to tissues and also increases relative concentration of CO2 in the blood. This repeated exposure of higher levels of CO2 to central chemoreceptor by multiple deep breaths, decreases its sensitivity and reduces SNS activity.
Secondly increased tissue oxygenation decreases stress on tissues and further decreases SNS activity.
Thirdly, during relaxed diaphragmatic breathing exercises stretching of lungs causes increase in both signal intensity and duration of slowly adapting pulmonary stretch receptors (SARs). These signals are generally inhibitory and travelled along vagus nerve to the brain stem.
Inhibitory signals in the brainstem improve synchronization between hypothalamus and brainstem and enhance overall PNS activity.
Breathing correctly reduces allostatic load
Allostatic load is the excessive damage of the body due to continuous exposure to stress. Stress hormones, in short run are important for adaptation and homeostasis. But over a long period of time, they can accelerate the disease process.
Breathing interventions by reducing the levels of circulating stress hormones decrease the allostatic load of the body and protects from many systemic disorders.
Right Breathing corrects under-activity of GABA system
PTSD symptoms (hyper arousal, heightened anxiety) are mainly induced by under-activity of GABA system- the inhibitory neurotransmitter system.
Studies have shown the continuous practice of breathing exercises by increasing level of GABA can lead to a calming effect on the mind and a sense of control of the body.
