Early Sirens is the first book ever to offer critical health warning signs long before sleep apnea so you can take proactive steps to head of CPAP mask and sleep apnea's many complications: heart attack, Alzheimer's brain, acid reflux, chronic pain, fatigue, stroke, high blood pressure, and more.In this sequel to his ground-breaking Six-Foot Tiger, Three-Foot Cage, Dr. Felix Liao has connected the dots of snoring, teeth grinding, jaw clicking, neck-shoulder-back pain, chronic fatigue, root-canals, and one medical and/or dental trouble after another, into a coherent WholeHealth explanation for sleep apnea - by linking poor sleep to choked airway to impaired mouth structures. Treating these leading oral-facial indicators as "canary in the coal mine" warnings early on can help head off CPAP masks and sleep apnea's other very costly medical and dental complications. Rich with real-life cases and scientific evidence, Early Sirens also offers a proactive Holistic Mouth as a natural solution to stop and reverse Impaired Mouth's dominos from falling toward sleep apnea. You will learn an Impaired Mouth is the anatomical cause of poor sleep, airway obstruction, and oxygen deficiency, and learn to recognize an Impaired Mouth with OneLook YouKnow(TM). Optional based on word count requirement- You will also see Holistic Mouth CSI(TM) (chair side investigation) putting the WholeHealth paradigm to work to solve Impaired Mouth Syndrome. "Is this body getting what it needs to stay healthy? If not, what's in the way?" Through this kind of Chair Side Investigation, Dr. Liao traces symptoms back to their root causes, just like Sherlock Holmes astutely picking up clues overlooked by others at the crime scene. The earlier you attend to Dr. Liao's early sirens, the sooner you will sleep well soon, feel great naturally, and keep your teeth, build natural health, stay young and age with much greater ease in the long run.
