[Recommendations for use] When using a cervical collar for the first time, you should first adjust it to a lower traction level to find a comfortable traction strength to reduce cervical pain After using it for a period of time, gradually increase the traction height to focus on comfort and protect your cervical spine. We recommend that you start using it for 5 minutes each time and gradually increase it to 15 minutes, so that the cervical spine can slowly and effectively traction. [Adjustable neck stretcher device] The cervical neck traction device is adjustable in both traction height and circumference, allowing it to fit more snugly around the neck. This close fit enables effective stretching of the neck, which helps relax your neck. Neck traction devices for home use represent one of the best drug-free methods to relax the neck, eliminating the need for endless physical therapy treatments or surgery. A cervical traction device can instantly relax your neck, allowing maximum mobility. Instead of being confined to a specific location, this device can be used anywhere - at home while watching TV, doing household chores, or even during work. [Neck Decompression Devices] There are a pair of knobs on the left and right sides of the cervical neck traction device, which can adjust the cervical traction height up and down to achieve neck decompression. Each time you turn the knobs on both sides of the cervical collar 180 degrees counterclockwise, the cervical collar will rise simultaneously and push the cervical spine, maintaining the same traction force on both sides of the cervical spine. In the initial stages of using a cervical neck traction device, simply start with minimal traction intensity. [Cervical Care] We spend most of our day at work and education, and even during leisure activities, our necks are under considerable stress. The cervical neck traction device provides a simple and effective solution, allowing you to spend only about 15 minutes a day using this cervical neck traction device to complete neck decompression and take care of your cervical spine.
