for most people this collapse does not occur because activation of the muscles surrounding the airway during sleep is still strong enough to prevent any blockage. when sufficient air doesn’t get into a person’s lungs, the level of oxygen in the blood falls and the level of carbon dioxide (a waste product of metabolism) rises. fortunately, with osa, after a period of not breathing, the brain wakes up, and breathing resumes. in other words, snoring is a sign of an obstructed airway, but it does mean that a person is breathing; silence might indicate that the airway is completely blocked. this reduces the duration and quality of sleep. in people with osa, repeated episodes of falling oxygen levels lead to a variety of physiological changes that affect the heart and blood vessels. during these episodes, the heart is stressed, which increases blood pressure and heart rate.
obstructive sleep apnea is the most common sleep-related breathing disorder. it causes you to repeatedly stop and start breathing while you sleep apnea causes breathing to be interrupted constantly during sleep. treatments include lifestyle changes and breathing assistance sluggishness or sleepiness (often seen as laziness); snoring; teeth grinding; restlessness in bed; breathing that pauses or stops; unusual, sleep apnea, sleep apnea, what are the warning signs of sleep apnea, untreated sleep apnea life expectancy, types of sleep apnea.
