When your body is in a static position for 49 minutes or less, it takes 20 minutes of movement therapy (yoga, bodywork, exercise, etc.) to release that pattern.  If it is in a static position for 50 minutes or more, it takes 3-4 hours of opposite action or movement therapy to release that pattern.  

The way you sleep effects your patterns, your posture, and your pain.  If you could sleep in a way that would allow your body to rest and let go of the stresses of your day in a therapeutic way, would you do it?
