Sleep Disordered Breathing (SDB) is a condition that describes the entire spectrum of abnormalities that occur during sleep. These range from mild breathing difficulties caused by problems such as a chronically congested nose to more severe conditions like snoring and sleep apnea. SDB is very common among mouth-breathers. As mouth-breathers struggle to get enough oxygen into their body while they sleep, the brain often causes the body to wake up enough to either change positions and open the airway or to gasp and take a breath. This results in fragmented sleep patterns which can lead to inflammatory processes in the body that are associated with conditions such as high blood pressure, stroke, cancer, heart disease, Alzheimer’s disease, diabetes, and depression. Fragmented sleep can also lead to symptoms that mimic ADHD and learning disabilities, as well as anxiety, poor coping skills, and peer problems. Children need to be able to breathe well while asleep for their rest to be restorative and for the brain to develop normally, and while asleep they should be silent and still.
