With Azazar Mouth Strips, you will breathe properly once again. We were all born obligate nose breathers. It was not until the muscles in our respiratory airway started developing that we began mouth breathing. And for years, most of us mouth breathe in response to a range of stimuli from stress to physical exertion. We mistakenly use our mouths to take deep breaths expecting that will maximize oxygen intake, calm us, or help us regain our energy. But mouth breathing does just the opposite. Mouth breathing causes increased anxiety by activating the sympathetic nervous system and lowers our oxygen saturation due to hyperventilation. Put simply, we should always use our noses for breathing.
