Text Neck and Blood Flow to the Brain.

Decreased Vertebral Artery Hemodynamics in Patients with Loss of Cervical Lordosis

Med. Sci Monit, 2016; 22:495-500

The authors wanted to determine the relationship between vertebral artery (blood vessels in the neck) and cervical lordosis (neck curve).
Loss of cervical lordosis (neck curve) causes disrupted biomechanics, triggering a degenerative process in the cervical spine.
The loss of cervical lordosis (neck curve) is associated with neck, upper thoracic, and shoulder pain, tension and cervicogenic headaches, and POORER HEALTH-RELATED QUALITY of the life outcomes.
The evaluation parameters included lumen diameter (LD: size of blood vessel), peak systolic velocity (PS: blood going into vessel), and end-diastolic velocity (ED: blood going out of vessels), and flow volume (FV).
The results of the study revealed that vertebral artery parameters, including LD, FV and PS, were significantly different between groups, with patients with LOSS OF CRVICAL LORDOSIS SHOWING LOWER VALUES in comparison to controls.
Axial load (weight of head) is shifted from posterior to anterior (back to forward) is lost, and the increased compressive forces triggers and accelerates the degenerative process.

Spine is a very delicate structure especially at the neck region because of nerves and blood vessels.
When you put your head forward to read phone or tablet, you are slowly changing the curvature of your neck.
“Text Neck”, is no longer a catchphrase but an actual medical diagnosis.
You are changing the function and health of your body when you change the position of your head, such as this article stated, reduced blood flow to the brain.
Posture is extremely important to the health; good posture can lead to better health.
