With the appearance of cervical spine, especially with the development of different stages of age, cervical spine and intervertebral disc can undergo different changes, leading to cervical hyperosteogeny and intervertebral disc degeneration, thus causing cervical spondylosis.

Then it is related to trauma factors, especially trauma leads to the rupture of intervertebral disc annulus, leading to disc herniation or bone destruction in cervical vertebra, which is easy to lead to cervical spondylosis in the later stage.

It is related to bad living posture, especially after bending over for a long time or sitting for a long time. Improper sitting posture can easily lead to changes in the curvature of the cervical spine, and the degeneration of the cervical spine can cause cervical spondylosis.

Being in a cold or humid environment for a long time can also easily lead to unexpected situations in the muscle ligaments of the neck, thus increasing the pressure on the intervertebral disc and causing cervical spondylosis.

Chronic strain and the patient's congenital neck dysplasia can also easily lead to the onset of cervical spondylosis.

Harm of long-term bad sitting posture to health;

First, it will cause damage to the spine. It is easy to become stiff when sitting on the spine for a long time. Many people like to walk forward, but they don't like to sit up straight or recline. This will put more pressure on the lumbar spine, which will easily cause lumbar muscle strain and even lumbar disc herniation.

Second, people who often sit for a long time will suffer from cardiovascular and cerebrovascular diseases. If you keep it for more than three hours every day, the risk of deep vein thrombosis in lower limbs will also increase.

Third, the gastrointestinal digestive function of sedentary body is weak. Food stored in the body for too long will cause indigestion, loss of appetite, diarrhea, abdominal distension and constipation.

Fourth, sedentary, the body's salt metabolism slows down, and the calories consumed by the body are far less than the calories consumed, which is easy to cause fat accumulation in the body and lead to obesity. Sedentary will also reduce the utilization rate of insulin to the human body, lead to insulin resistance, and greatly increase the risk of type 2 diabetes.

Reducing the harm of sedentary means correct posture, getting up and walking every 40 minutes, which can reduce the harm to the body.
