What is obstructive sleep apnea?
Obstructive sleep apnea occurs when, during sleeping, your throat walls relax and/or your tongue flops back to block the upper section of the airway. This can lead to a temporary stopping of breathing, known as apnea. This can cause an interruption in sleep, as your breathing can stop for a period of a few seconds to about a minute. When your brain registers that you have stopped breathing, a wake-up signal is sent and you begin to breathe again. Apneas can occur many times through the night, often without you noticing, but causing you to feel tired the next day.
