Indeed, alongside the invasion of wind-cold-dampness described in the Donguibogam—or perhaps even more commonly today—slouched posture and stress torment our necks and shoulders. Often termed forward head posture or straight neck syndrome, this condition occurs when the cervical spine loses its natural C-shaped curve and the head pokes forward like a turtle. This is far from just an aesthetic concern. The head is heavier than many realize; did you know that for every centimeter it tilts forward, the load placed on the neck increases by 2 to 3 kg? Consequently, supporting muscles such as the suboccipital muscles, trapezius muscle, and splenius cervicis muscle become abnormally tense and overworked, triggering muscle pain and inflammation. Chronic tension alters muscle fiber structure and forms trigger points, generating persistent pain.
Furthermore, these postural abnormalities can affect blood circulation toward the brain. Crucial blood vessels and nerve fascicles bound for the brain pass near the neck, and when rigid muscles compress them, symptoms such as headaches, dizziness, and even blurred vision can develop. Specifically, compression of the occipital nerve at the back of the neck may provoke occipital headache, causing a shooting, tingling pain in the rear of the head. It also impacts the autonomic nervous system: leading to sympathetic hyperactivity, it can provoke systemic symptoms including increased heart rate, anxiety, and sleep disorders. The liver qi stagnation discussed in the Donguibogam can be interpreted in modern medicine as a chronic increase in stress hormone secretion (such as cortisol) and sympathetic nervous system activation. Ongoing stress prompts muscle tension, accelerates vasoconstriction, and lowers the pain threshold, causing a person to feel greater pain from even minor stimuli.
In clinical practice, magnetic resonance imaging and x-ray examinations often reveal not only misalignments of the cervical vertebrae, but also degenerative cervical disc changes and abnormal thickening of surrounding ligaments and muscles. This can evolve into a complex issue that simple posture correction alone cannot resolve. Because a compromised spinal structure does not easily recover once damaged, attentive management from the earliest stage is vital. While smartphone and computer use has become an unavoidable reality of modern life, active efforts are needed to protect the neck, one of our body's most critical pillars. Fundamental improvement can be expected when modern medical treatments such as physical therapy, manual therapy, and nerve blocks are combined with maintaining proper posture and managing stress.
