Nitric Oxide. Why nasal breathing may not be enough ?
The benefits of nasal breathing and Nitric Oxide is well documented. Nasal breathing helps with the production of Nitric Oxide. However, the production of Nitric Oxide is dependent on the Carbon Dioxide level in the body. Low Carbon Dioxide means less Nitric Oxide production even with nasal breathing.
Electromyograph (EMG) helps to detect subtle chest breathing resulting in lower carbon dioxide level.
