With CPAP therapy, ideally, you should breathe in and out through your nose only. Despite best efforts to do this, sometimes;
- You wake up with a dry mouth.
- Mouth leaks occur due to high CPAP pressures.
- Swallowing air makes you feel bloated.
These are symptoms that your mouth may have been open during sleep.
Chin Straps apply upward pressure to the chin to help keep your mouth closed during sleep. It will also allow you to take advantage of a wider range of masks including Nasal and Nasal Pillow Masks.
