What happens every time we get a bit of shut eye? Sleep occurs in a recurring cycle of 90 to 110 minutes and is divided into two categories: non-REM (which is further split into four stages) and REM sleep. Non-REM sleep. Stage one: Light Sleep. During the first stage of sleep, we're half awake and half asleep. Our muscle activity slows down and slight twitching may occur. This is a period of light sleep, meaning we can be awakened easily at this stage.
Obstructive sleep apnea occurs when the muscles in the back of your throat relax. These muscles support the soft palate, the triangular piece of tissue hanging from the soft palate (uvula), the tonsils, the side walls of the throat and the tongue.entral sleep apnea is a less common form of sleep apnea that occurs when your brain fails to transmit signals to your breathing muscles. This means you make no effort to breathe for a short period of time. You may awaken with shortness of breath or have a difficult time getting to sleep or staying asleep.
