To avoid compressing the intervertebral discs, it is essential to maintain the natural S-curve of the spine.

 The intervertebral discs are among the most burdened tissues in the body, yet they have almost no blood circulation. As a result, they receive limited nutrients and are one of the first parts of the body to begin aging, often as early as the late teenage years. With aging, the discs lose their hydration and can no longer function effectively as cushions, causing them to compress. 

This places strain on the surrounding joints, ligaments, and muscles, making the neck and lower back more prone to pain. As the condition progresses, the spine may shift or deform, leading to nerve compression within the spinal canal and resulting in symptoms such as numbness or paralysis.
