Cervical spondylosis is a strain degenerative disease of the cervical spine, related to long-term head-down and neck-flexing movements, common in the middle-aged and elderly, but in recent years, with the accelerated pace of life, the age of onset of cervical spondylosis also tends to be younger. In the lighter cases, it only shows the discomfort of soreness and swelling of the neck, but in the heavier cases, it can compress the nerves leading to the upper limbs or the vertebral artery leading to the brain and cause soreness, numbness and pain of the arms and fingers or vertigo, or even compress the spinal cord and cause weakness or paralysis of the limbs. Therefore, we should pay attention to the hazards of cervical spondylosis in life. Although the process of cervical degeneration cannot be reversed, the process of cervical disc degeneration can be avoided or slowed down by some of the following preventive measures, or to help patients relieve their symptoms. Patients with cervical spondylosis should do more functional neck exercises, especially neck extension movements, which on the one hand can keep the cervical joints in a certain range of motion to avoid degeneration and stiffness of soft tissues such as joint capsules and ligaments; on the other hand, it can make the neck muscles developed, increase support and enhance the stability of the cervical spine to avoid strain and atrophy of the neck muscles. In the morning when the mouthwash by the way to move the neck, is a two-fold thing. Bad posture in life such as high pillow, sedentary low head and improper twisting of the head and neck, will accelerate the degeneration of the cervical spine, the back of the neck paravertebral muscles due to continuous tension and easy fatigue, resulting in chronic strain on the soft tissues of the neck, cervical joints will also be strained. So it is best to take a break in an hour or two in the busy work, or change the position or movement. Sleeping with a high pillow at night makes the cervical spine flexion, and over the years, will increase the cervical strain, life should avoid the bad habit of lying on a high pillow, choose a pillow with a height of about 10cm and a moderately hard and soft concave pillow to help alleviate the symptoms of cervical spondylosis and prevent the onset of cervical spondylosis. When reading a book naturally to lower the head to the book, if the book with a bracket placed diagonally, the head can be slightly raised, do not have to flex the neck for a long time. Supporting the chin with the hand when using the brain is undoubtedly a good habit for cervical spondylosis patients. At the same time, pay attention to the prevention of wind and cold and humidity in life, avoid midnight and early morning bathing or wind and cold blowing, prevent trauma in life can also prevent the onset of cervical spondylosis Once trauma occurs, in addition to the treatment of soft tissue injuries, but also timely treatment of small joint dislocation of the cervical spine, in order to prevent the development of cervical spondylosis. Cervical spondylosis can cause cerebral ischemia and dizziness if the vertebral artery is compressed, and the pressure increases when the head is tilted back or when the head is turned. The cervical degeneration of the bone flab or protruding disc compression to the nerve will cause numbness and pain from the upper limbs to the fingertips and weakness, cervical traction can expand the intervertebral foramen, reduce the compression of the nerve root, the symptoms will naturally ease, but the angle, weight and time of traction is very delicate, if traction at home, it is best to consult the physical therapy or orthopedic surgeon’s opinion.
