The term straight neck syndrome has become common today. Our cervical vertebrae naturally maintain a C-curve, known as cervical lordosis. It is a vital structure that absorbs shock like a spring and efficiently disperses the weight of the head. However, when you crane your neck forward or slouch repeatedly while looking at smartphones and computers, this C-curve gradually straightens. In severe cases, it bends backward into cervical kyphosis. This condition is called straight neck syndrome or forward head posture syndrome.
Straight neck syndrome does not simply cause neck pain. When the cervical vertebrae become straight, they fail to disperse the head's weight, which reaches up to 7 kg, placing an immense burden on the neck and shoulder muscles. If narrow neck muscles have to hold up the equivalent of a bowling ball every day, strain quickly accumulates. As a result, the trapezius muscle, sternocleidomastoid, and levator scapulae around the neck become chronically tense and rigid, impairing blood circulation and accumulating metabolic waste. This excessive muscle tension can cause neck pain, shoulder stiffness, back pain, and even hand numbness due to nerve compression.
From the perspective of neurology, vital blood vessels and nerve fascicles heading toward the brain pass around the cervical vertebrae. When straight neck syndrome compresses these structures, blood flow to the brain becomes compromised, leading to chronic headache, dizziness, impaired concentration, and even tinnitus or eye fatigue. The concept of liver wind in the Donguibogam closely aligns with autonomic nervous system imbalance caused by stress and overwork. Stress induces muscle tension, which leads to circulatory disorder and accelerates inflammatory reactions around the neck in a continuous cycle.
If this state persists, the risk increases that the discs between the cervical vertebrae will fail to endure the pressure, protruding to cause cervical disc herniation. Rather than ignoring these changes, it is important to pay attention to these subtle signals from your body before the natural curve is lost.
