What is it?
Sleep apnoea is when the walls of the throat constrict during sleep, blocking your airways.
When your throat is closed, you don’t get enough oxygen. As your brain registers this, it kicks in and wakes you slightly, causing your airway to open. During this process, the person often snorts and gasps and this can happen hundreds of times per night, depending upon the severity. The result is restless, poor sleep.
