Abstract Changes in breathing during pranayama (yoga breathwork) are usually inferred from practice guidelines in traditional texts or contemporary writings.

Evaluating relationships sheds light on the perceptual and cognitive changes induced by yoga and related methods, and the locus of the effects. In the present study, the degree of optical...
