What is Obstructive Sleep Apnea?

Sleep apnea is defined as an interruption in breathing during sleep. Usually when we are awake and conscious, we are aware of our breathing process and we can control the rate and rhythm of breathing. During sleep, breathing is controlled by the respiratory brain centers. It is a totally involuntary action which can not be controlled by one’s will. In sleep apnea, there is interference in the normal regular breathing process during sleep.
