Breathing problems people experience during sleep are been called one of the most damaging, but least diagnosed conditions in modern medicine. We spend nearly 1/3 of our lives sleeping, but more than 20% of people are not getting effective rest and in many cases are having severe medical conditions because of OSA. Most common is cardiac stress where the heart rate can exceed 200 beats/minute before you are awakened. OSA is clearly linked to high blood pressure, stroke, arrhythmia, and heart failure. New research is also attributing increased incidence of memory problems and Alzheimer disease; possible because there is insufficient "cleansing" of the brain when sleep is interrupted.
Left untreated, the incidence of heart attacks is 30% higher in OSA patients.
Of course, we have all heard of couples where snoring has caused significant stress to one's bed partner.
