Cervical traction belt is a medical device used to treat cervical related diseases or symptoms, such as cervical spondylosis, cervical disc herniation, cervical degenerative diseases, etc. Its function is to relieve neck pressure, alleviate pain, and improve neck posture and function by applying traction. The following are the general functions of cervical traction belts:

1. Reduce neck pressure: The traction belt can apply gentle traction, stretching the soft tissues and ligaments of the neck, helping to reduce pressure and tension in the neck.
2. Relieve neck pain: For neck pain caused by cervical spondylosis, cervical disc herniation, etc., traction straps can help alleviate pain by stretching the neck structure to relax tense muscles and nerves.
3. Improving neck posture: The use of traction straps can help adjust the posture of the neck, especially for those who experience neck flexion due to prolonged work or poor posture.
4. Promote cervical spine rehabilitation: After neck injury or surgery, traction straps can serve as rehabilitation tools to help accelerate the recovery process of the cervical spine and promote the healing of the injured area.
5. Increase neck range of motion: The use of traction straps can increase neck range of motion, helping to restore neck flexibility and motor function.
6. Improving blood circulation: Traction straps can improve blood circulation in the neck, aid in nutrient delivery and elimination of metabolites, and promote the health of neck tissues.
7. Provide comfort and safety: well-designed traction straps typically have soft and comfortable materials that provide a comfortable feeling when worn and ensure safety.

Overall, cervical traction straps play an important role in treating neck diseases and symptoms, relieving pain, improving posture and function, and promoting neck recovery. However, it is best to consult a doctor or professional healthcare professional before use to ensure proper selection and use, and to avoid potential risks.
