1, the cervical vertebra structure is normal: the neck is composed of seven cervical vertebrae, and the cervical vertebrae maintain normal physiological radian, gap and uniform stress distribution to avoid diseases such as cervical spondylosis.
2, muscle strength: the neck muscles are an important part of supporting the neck, and appropriate exercise should be carried out frequently to maintain muscle strength and flexibility and avoid problems such as muscle atrophy.
3. Vascular patency: The neck is an important part close to the brain. The health of blood vessels in the neck will affect the blood supply to the brain. Neck blood vessels need to be kept unobstructed to avoid problems such as hypertension and vascular stenosis.
4. The nerves are normal: there are many nerves passing through the neck. Nerve injury or compression can lead to various discomforts or pains in wrists, hands and shoulders. Nerves should be kept in a normal state to avoid nerve damage and other problems.
