After a hard day's work, I finally come home from work. Of course, I have to "wow" into the arms of the sofa! However, experts warn that potatoes who love to make sofas do not pay attention to sitting posture, which not only fails to achieve the purpose of relaxation, but also may cause annoying trigeminal neuralgia, dizziness and temporomandibular joint pain under the long-term improper oppression of cervical vertebrae. Therefore, in order to prevent the above symptoms, it is very important to know what is improper sitting posture on the sofa and avoid making mistakes again.
Is sofa a physical and health killer? This is the problem!
Some people will ask, just lying on the sofa. Is it that serious? Zhang, a doctor of spinal neurology in the United States, said that from the perspective of spinal neuroscience, sitting on the sofa for a long time and sitting improperly will not only easily hurt the lumbar spine, cause backache, but also endanger the health of cervical spine.
In particular, there are quite a few sofa styles on the market. Some sofas are deep in design and soft in material, so it is easy for people to get stuck when they sit down. This type of sofa is easy to make people sit in the wrong position when using.
In addition, the depth of the sofa is too deep, which will cause the distance between the back of the human body and the back of the sofa to be too far, leading to people lying on their back/sitting back, and showing a semi-lying (hunchback, bow down) ng posture due to the lack of sufficient support of the cervical and lumbar vertebrae. Improper use for a long time will naturally become a killer of posture and health.
Love to lie on the sofa and sleep on the sofa? Beware of five health problems.
In addition, many people like to sleep on the sofa, that is, lying flat/sideways on the sofa directly, and using the sofa armrest (grip) as a pillow is a great punishment. Dr. Zhang mentioned that this posture may damage the nerve tissue around the cervical vertebra, which plays an important role in transmitting nerve and brain information, and increase the risk of the following health problems:
Problem 1/ Shoulder and neck pain &; Temporomandibular joint pain:
Because the temporomandibular joint is too close to the back of cervical vertebra and muscle groups (especially cervical vertebra 1 and 2), and its structure, function and nervous system are closely combined. Therefore, if the human body is often in bad posture such as hunchback, it is prone to temporomandibular joint pain, causing pain in the back neck; Or, temporomandibular joint pain caused by back neck pain, even accompanied by tinnitus and ear swelling.

Question 2/ Foreign body sensation in throat:
Long-term improper neck compression is more likely to cause abnormal contraction of peripheral nerves and muscle tissues, causing people to feel stuck in the throat, foreign body sensation and neck discomfort. Dr. Zhang said that he had encountered such a case in clinic. Because of the compression of cervical vertebra, he felt suffocated, as if someone had pinched his neck, and even thought he was "stuck in the shade". Fortunately, tossing and turning to find out the reason, after appropriate adjustment, there is no serious problem.
Question 3/ Neck-related headache:
Bad neck posture is easy to make the arytenoid muscle in the back of the brain in a state of excessive tension, which in turn compresses the nerves and induces neck-related headaches. Common symptoms include unilateral pain and dizziness in the back of the head, eye socket, orbit, temple and forehead.
Question 4/ Autonomic nerve disorder:
Because of the existence of vagus nerve, the largest parasympathetic nerve in cervical spine. Therefore, abnormal cervical spine problems caused by poor posture, such as spinal dislocation and hunchback, are one of the key factors to induce autonomic nerve disorder, leading to palpitation, chest tightness, headache, dizziness and other symptoms.
Question 5/ Trigeminal neuralgia:
The main symptom of trigeminal neuralgia is facial pain, usually unilateral pain. The most common pain site is the cheek, and patients are easily accompanied by intermittent severe neuralgia, electric shock pain, or knife cutting pain.
Therefore, Dr. Zhang stressed that once a person has one of the above symptoms, he should rule out potential disease factors such as tumor and thyroid abnormality after seeking medical treatment. It needs to be considered moderately, which may be caused by improper compression of the peripheral nerve of the neck. It is suggested to actively seek the help and conditioning of a chiropractor with a professional license.

Correct incorrect sofa posture 3 90 degrees+make good use of pillows and cushions to help improve.
In addition to seeking expert assistance, Dr. Zhang also mentioned that the most important thing to prevent the above discomfort is to learn to use the sofa correctly and avoid the oppression of cervical vertebrae and lumbar vertebrae caused by improper posture!
The following is a special demonstration to teach you how to correct the common improper posture of sitting on the sofa:
Three 90 degrees
1. Ankle on the ground, 90 degrees perpendicular to the ground.
2. Knees close to the edge of the sofa chair, 90 degrees close.
3.*** (lumbar vertebrae) should be 90 degrees perpendicular to the sofa chair surface.
If it is below three 90 degrees, the distance between the back of the sofa is quite far, indicating that the depth of the sofa is too deep. It is suggested that the pillows and cushions at home can be moderately supported, and the lumbar and cervical vertebrae have slightly convex curves, which is a good sitting posture. However, even if sitting correctly, people are advised not to sit for a long time. It is best to get up and exercise every 20 to 30 minutes, up to 50 minutes.
