Are you feeling sleepy all the time? Do you snore? Is your doctor having a difficult time treating your high blood pressure? If you answered yes to any of these questions, then you might have Sleep Apnea (also called Obstructive Sleep Apnea or OSA).
Sleep Apnea is a condition involving pauses or decreases in breathing during sleep. It is usually due to airway collapse. This collapse occurs in the nose and/or the throat anywhere from where air enters the nostrils to the back of the tongue. Imagine a straw collapsing when trying to suck on a thick milkshake. Frequently, this airway collapsibility problem is inherited and starts in childhood. In the daytime, it is not a problem because there is good muscle-tone in the airway and the brain monitors breathing. But at night, the throat muscles become relaxed and the brain is not as attentive to the airway. So on inhalation, the airway walls can either completely collapse or significantly narrow. This is a problem because 1) the body must struggle to breathe and 2) the brain has to wake up to reopen the airway.
These frequent awakenings lead to fragmentation of nighttime sleep. You may not remember them...
