Is there or has there been any research about the cognitive benefits of using the breather device?
This area of investigation has only emerged recently but is followed with great attention. A study using very weak respiratory exercise (incentive spirometry) in elderly people has shown that respiratory exercise provides cognitive benefits such as improved semantic memory, mental flexibility and attention when compared to physical exercise or social contact alone. Other indications on the benefit of RMT on cognitive functions come from training at high altitudes, where RMT improves processing speed and working memory. Currently, a clinical trial is recruiting that will investigate the cognitive benefits of RMT in patients with heart failure.
While the cognitive benefits of the Breather have not been documented yet, benefits observed with similar (and less effective, in the case of incentive spirometry) methods imply that the Breather should yield similar or even stronger effects on cognitive functions in elderly people, patients and at altitude.
