SEFUDUN 120 Pcs Mouth Tapes - Advanced Anti Snoring Devices Gentle Mouth Tape for Sleeping, Sleep Strips for Better Nose Breathing, Less Mouth Breathing: With SEFUDUN 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. SEFUDUN Mouth Strips are the simple, gentle way to improve your sleep quality, non-invasively controlling your physiology to increase airflow and reduce mouth breathing and mouth snoring. After all, good sleep is the key to enhanced health, fitness, and cognitive function. With Mouth Strips, we make good sleep as simple as using your nose.
