Mechanics of Sleep Apnea Show Why It's Perilous
Posted by Admin on September 14, 2010
Sleep apnea – in which a sleeping person repeatedly ceases breathing for intervals – restricts the brain’s blood flow and raises its blood pressure, eventually disrupting the brain’s ability to control these dynamics and shield itself from damage, a recent study showed. The study, published by the American Physiological Society in the Journal of Applied Physiology , was performed by researchers at the Yale University School of Medicine in New Haven, Conn. The results revealed why America’s 18 million sleep apnea sufferers are at much greater risk than others for stroke and for dying in their sleep.
