Vyana Vayu Mudra is a yoga hand gesture to improve the flow of Vyana Vayu – the circulating current of the breath. Performing the gesture improves blood circulation and the biological functions related to the organs and glands in the chest region.

Vyana Vayu is one of the five parts of prana – the vital breath. Our breath is divided into five sub currents called Pancha Prana (five types of prana). These currents are categorized as Prana, Udana, Vyana, Samana, and Apana Vayu.

Each current of the breath is associated with a particular region of the body. They play a crucial role in regulating the biological functions of the organs and glands in that region. This theory of the five prana winds is an important aspect of traditional medicine in the Indian sub-continent.
