“One common problem caused by postural faults is forward head position, in which the head is sitting forward of the spine. In this posture, for every inch the head moves forward, the weight of the head on the spine increases by an additional 10 pounds. People whose head is sitting 3 inches forward of their shoulders are now supporting 42 pounds of weight, compared to what is typically 12 pounds in aligned posture. This can occur in both sitting and standing postures. It can pull the spine out of alignment, reduce lung capacity inhibiting complete lung aeration, contribute to a sluggish gastrointestinal system, cause tension headaches, and decrease balance. Most devastating is if forward head posture leads to cervical spine instability, as a result of constant strain on the ligaments which stabilize the neck. A stable cervical spine protects the spinal cord and brainstem. The laxer the ligaments, the stronger the muscles must be support the head and neck.” — Diana Jovin
