Neck is a critical part to maintain good health
Improper posture of neck can cause headaches, rhinitis, cerebrovascular diseases and dementia. Since nerves and blood vessels pass through the neck, maintaining good neck condition is important. For instance, if the neck is seriously bent, the brain might not function normally due to the lack of blood flow.
