For every inch that the head moves forward in posture, it increases the weight of the head on the neck by 10 pounds!
Poor neck posture leads to a Forward Head Position which is one of the most common causes of neck, head & shoulder tension – and pain. This can be a result of injuries – such as sprains & strains of the neck, leading to weak neck muscles; poor sleeping positions and driving stress; plus computer neck, couch neck & readers neck – all of which also lead to reduced breathing capacity.
The extra pressure on the neck from this altered posture flattens the normal curve of the cervical spine resulting in abnormal strain of muscles, ligaments, bones and joints of the neck – causing the joints to deteriorate faster than normal, resulting in degenerative joint disease or neck arthritis.
