Are there different styles of Pranayama?

Is there a “right” breathing technique?

We designed an approach based on Visamavrtti Pranayama; the object being to train people to prolong and regulate their breathing in simple way. In this way we obtain both physiological benefits as well as clarity of thought.

Our purpose is to train people in a method that is intuitively designed, easy to understand, and suitable for both beginners and advanced practitioners of yoga. Our application is designed to be used easily during your busy day. The app's intuitive exercises can be approached without a lot of training or effort, thus lowering the barriers to getting you started on improving your health.

For Inhalation- Breathing in through the nose is natural and beneficial, the nose filters, warms and moistens the air, thus protecting your lungs.

For Exhalation- As we are trying to build up lung capacity to take deeper and prolonged breaths, we want to be able exhale fully with minimal effort and strain, and this is most easily accomplished exhaling through the mouth, as there is no resistance to airflow in the mouth as there is in the nose. Therefore exhaling through the mouth is the most widely suitable method and adapts well to everyday life.

Different forms of Yoga have different purposes and different breathing techniques. Therefore in some forms you do exhale through the nose during the yoga training, but not through out the normal day. Our purpose was to train people in a method that would be suitable for most people, easy to understand and structured; which would teach behavior and techniques most suited for everyday life.
