a. Usually when you sleep, the muscles in your throat hold your airway open. This allows air to flow freely from your nose and mouth to and from your lungs.

b. In some cases, these muscles relax too much during sleep, blocking (or obstructing) the airway. This means that air can’t get to or from the lungs. The body then realizes it isn’t getting enough oxygen and wakes you up. This may happen hundreds of times during sleep, even though you may not be aware of it. This breaks up your sleep and can make you feel very tired and affect your overall health.
