We all know the importance of getting a full eight hours of sleep each night. Tossing and turning, waking up continuously through the night and snoring can disrupt the crucial REM (rapid eye movement) sleep we desperately need for our bodies to heal and regenerate each night. If sleep is disrupted on a regular basis, an underlying condition called sleep apnea may be the culprit. Sleep apnea is a sleeping disorder in which breathing repeatedly stops and starts. It's a potentially serious disorder, but also manageable with proper therapy or treatment. As if stopping breathing isn't scary enough, studies show the common sleep disorder can increase the risk of developing Alzheimer's disease, result in an earlier onset or worsen symptoms.
