Research shows that 90% of modern people over-breathe. Like over-eating, over-breathing or hyperventilation is detrimental to our health. Chronic over-breathing contributes to a number of chronic diseases, such as asthma, high blood pressure, heart disease, allergies, mental disorders, diabetes, cancer, etc.

Then what is normal breathing? The key is the breathing volume in one minute or Minute Ventilation. The physiological norm is 6 liters for a 70 Kg adult at rest. As a typical example of over-breathing, asthmatics tend to breathe at twice the normal volume. In the 1950s of the last century, Dr. Buteyko discovered the link between hyperventilation and asthma, and the Buteyko Method developed after that has cured hundreds of thousands of asthmatics since.

The critical factor to achieve normal breathing is the CO2 level in our body, which most of us have a lower-than-normal level.

The goal of reduced breathing is to train the brain to adapt to higher CO2 concentrations during a sustained period of air hunger by reducing the amount of air to breathe so that over time as a result, the CO2 level in our body will be increased towards a normal level.

Nowadays, more and more people become aware of the benefits of Buteyko Reduced Breathing and practice the Method in an ever-increasing trend, among them from asthmatics to mental disorders, and even elite athletes, just to name a few.

However, there are a number of challenges to learning and practicing Buteyko Breathing. One is that there are limited qualified Buteyko Method practitioners, and the other is lacking an effective tool to assist the practice.

One of the difficulties to practice reduced breathing is how to control air hunger properly: doing too little or too much will not give good results.

For example, light air hunger is defined as 5 – 10% less than the normal breathing volume, however, human is not born to have the ability to sense it properly, and this is what AYO breathing trainer can do best: measuring breathing volumes such as Minute ventilation and Tidal Volume along with a large number of breathing data.

By setting your target minute ventilation based on your desired air hunger, you can easily follow the App of the AYO breathing trainer to see your Tidal Volume cycle by cycle and Minute Ventilation every minute, thus making you know exactly how much air you actually reduce on each cycle and on average of the entire training session without guessing.

Training reduced breathing in this quantified way will guide your reduced breathing more effectively.
