Studies of resistance breathing and steam breathing

In addition to being developed by experts in health care, wellness, and technology, WellO2 Oy has a highly qualified medical advisory board that develops scientific research activities related to its effects as well as monitoring international research and development in respiratory rehabilitation and commenting on related international publications.

No clinical studies has yet been executed with WellO2 device. Several studies of WellO2 are currently ongoing, and two of them will be presented at the European Respiratory Society (ERG) international congress on September 6, 2022.

A pilot study related to WellO2's effects on voice production has been published. After using the WellO2 device for 10 minutes a day for a month, the participants reported that their voice problems were alleviated. Read the pilot study here: https://pubmed.ncbi.nlm.nih.gov/31416750/. 

Resistance breathing and steam breathing have been studied separately for a variety of breathing problems. Here are a few references:
