This is what it says on wikipedia:
However, the practice of pranayama techniques is not trivial and Kason mentions circumstances where pranayama techniques might disrupt the balance of a person's life.
[11] These cautions are also made in traditional hindu literature, as illustrated by the following excerpt from the Yoga Sutras of Patanjali:
The real achievement of Pranayama is directly linked with the physical and mental activity of our, daily routine. Only when a perfect order is achieved in the routine of mundane life can we expect perfect mastery over breath and vital pulsations. It is always dangerous to attempt it - by beginning with the control of breath. Trying to control the breath without a control of our daily movements and reactions to others will produce dangerous turmoil in the constitution. Any experiment with the breath results in a stimulation of the energy centres on the etheric plane. When the physical and emotional stuff is not sufficiently purified beforehand then the turmoil causes stormy activity of the emotions. This results in great strain to the nerves and the vascular system. A total or partial wreck of the physical vehicle by paralysis, insanity or senility of mind may be the result of attempting Pranayama beginning with the control of breath before achieving the control of other activities.
A practical way of practising Pranayama should always be rightly discriminated, by the increase of ease and absence of discomfort at every step. For the various methods of Puraka, Kumbhaka and Rechaka described by various teachers and prescribed in the name of 'esoteric breaths' the present author is no way responsible.
