As we continue to stress our necks in the ways I described in Headaches Part 1, our body does what it is designed to do...adapt. With forward head posture you will gradually lose the normal curve in your cervical spine (neck). This curve is important for decreasing the shock of impacts while you are standing or sitting upright. If this curve is straightened out it will lead to damage to the discs in the cervical spine and arthritis. (I will write a section about discs at a later date that will explain the causes and prevention.) If left untreated this curve can even reverse!
As you examine these pictures I want you to try and picture the muscles that surround your neck. While your head is forward the muscles in the front will shorten and the ones in the back will lengthen. This is exactly the opposite of what they were meant to be. When the muscles in the back are stretched they also become over worked because as your head moves forward the stress on the muscles increases dramatically. Your head weighs in at about 10-15 lbs. So imagine holding a bowling ball out away from your body all day.
