The modern concept of Yoga is explained in terms of integration, harmony and balance. This can be the effective methods in alternative and/or complementary medicine for the management of chronic functional disorders. It contributes to the holistic health through promotive, preventive and curative method .
Different yogic techniques bring control effect, which means the minor changes of the internal environment of the system towards a state of normal and optimal balance. This homoeostasis is maintained by the balance of sympathetic and Para-sympathetic component of autonomic nervous system as well as by the endocrinal system.
How to practice breath holding techniques?
Breath holding techniques will be introduced slowly and with proper guidance and experience. The patients should advise to practice the technique in the absence known cardiac problem. These techniques appear to pose no threat when done properly and introduced gradually for normal subjects.
Cardiovascular effects of breath holding
The heart rate decreases if the breath is held after maximum inhalation and increases after maximum exhalation due to pressure against the closed airway. Strong exhalation pressure, positive intrapulmonary pressure can increase heart rate above the baseline . The reduced peripheral blood flow is accentuated by exhalation pressure during breath holding.
Breathe holding and Sympatho-Vagal balance
Breath holding and the dive response can initiate both parasympathetic and sympathetic cardiovascular responses. Heart rate slowing is apparently mediated by the parasympathetic system whereas the reduced peripheral blood flow results from increased peripheral sympathetic activity. Finally, breath holding helps to restore the Sympatho-Vagal Balance is analyzed by a simple, noninvasive method known as Herat rate variability (HRV) .
Impact of psychological factor on breath holding
Psychological factors can override or enhance the autonomic responses to breathe holding . Mental distraction or preoccupation during breath holding or the dive response can increase and decrease the cardiovascular responses to breathe holding.
Precautions for practicing breath holding in cardiac patients
Breath holding and the dive response can induce a variety of cardiac arrhythmias in patients with significant pre-existing heart abnormalities. The strong parasympathetic cardiac stimulation from the dive response has been successfully and safely used as a means of halting paroxysmal atrial tachycardia, but requires extreme caution in patients susceptible to ventricular abnormalities because dangerous arrhythmias can be induced .
Yoga can be a practical tool to Body-Mind integration for the holistic healing and positive health. A systematic attempt to implement Yoga into formal healthcare system may bring great benefits to general public. For this, healthcare professionals may have general knowledge of Yoga and the right perspective of its application.
Effect of advanced breath holding practices on various physiological parameters can be investigated for future research study.
