The Sleep-Wake CycleInstinctively, we seek comfort & balance.Scroll to learn more.When we sleep,         we naturally try to find the most comfortable position

    - this includes using our headrests to support and balance our heads.
To achieve balance, our            neck
extensor

     muscles

         instinctively


compress


     the exterior


            neck padding to reposition our heads




onto the headrest, requiring continuous physical exertion by our necks.
As we begin to drift into sleep, our
    neck muscles

            begin to

                relax.


When this happens, our


            neck and head are pushed forward



              by the pillow, resulting in our heads falling forward once again.
We wake.       And we          start           the process once
       again.
