Many people can't stand the discomfort such as sore neck, pain, stiffness and limited activities, especially those who sit at their desks for a long time or often bow their heads to work.

The main reason is that the neck is in a posture or improper posture for a long time, which can easily cause excessive tension in some muscles of the neck, thus causing the above discomfort symptoms.

In addition, the slender but not rich neck muscles are also one of the reasons why the neck muscles are prone to excessive tension and strain.

Among the neck muscles, trapezius muscle is the most fragile. The trapezius muscle starts from occipital protuberance, nuchal ligament and spinous process of the seventh cervical vertebra, and gradually extends to the L/3 posterior edge of the lateral clavicle.

The trapezius muscle mainly controls the flexion and extension of the neck. If the head and neck droop excessively or the cervical spine bends forward, the trapezius muscle will be in a state of tension. In work and daily life, trapezius muscles are more likely to be injured, such as staring at the computer screen for a long time in the office, and this posture is maintained for too long; Or when women wear high heels, due to biomechanical changes, the chest, neck and head lean forward, which will make the trapezius muscle in an excessive state of tension.

Another fragile neck muscle is the sternocleidomastoid muscle.

This muscle is easy to find, as long as you twist your head to one side, you can clearly feel this prominent muscle. The main function of sternocleidomastoid muscle is to make the head and neck rotate to both sides. Carrying a backpack on one shoulder, carrying a box in one hand, or answering the phone with a microphone on your head, etc. , can easily contract one side of the sternocleidomastoid muscle, making it too tense and damaged.

In addition, psychological stress will also be reflected in the neck, resulting in neck pain symptoms.
