The sleep apnea chin strap is a pretty simple contraption. Being little more than a fabric band that is worn like a harness over the skull and under the chin, this type of chin strap for apnea is gaining a lot of popularity, partly because it is cheap and readily available, but mainly because it offers a non invasive solution to sleep disorders for many owners.
The chin strap cradles the chin during the night, and prevents the sleeper from breathing through the mouth, ensuring that a natural nose breathing pattern occurs, The adjustable models allow you to extend the lower jaw a little to aid the preservation of a clear airway. This jaw repositioning is a very useful feature, and works in the same way that the head position that is maintained whilst in the first aid recovery position does.
