Cell phone, is the “ideal partner” of modern people, it set communication chat, leisure and entertainment, shopping and consumption and other functions in one, so that many modern people’s eyes and thoughts are always intertwined with it, difficult to part with, willingly for it to lower the noble head, often as “low head “Like, so the “low head” was born. When “head down” has gradually become the main theme of life, the lack of communication between people, perhaps we are in the reduction of face-to-face contact may cause embarrassment and distress, but our body is protesting, our health in protest, and “head down” The most direct victim of “head down” – cervical spine, is in their own way strongly protest! And the performance of the protest is “cervical spondylosis”. Definition of cervical spine and cervical spondylosis Cervical spine: The cervical spine is an important anatomical structure that connects the head to the torso (thoracic spine) and consists of seven vertebrae and five intervertebral discs, as well as joint capsules and ligamentous structures to provide mechanical stability. It not only supports the head to connect to the body, but also supports the blood vessels and nerves that connect the head to the body. It can be simply understood that if this bone in your neck breaks down, your body is likely to have a major problem. Cervical spondylosis: also known as cervical spine syndrome, is a general term for cervical osteoarthritis, hyperplastic cervical spondylitis, cervical nerve root syndrome, cervical disc prolapse, is a degenerative pathology based on the disorder. As early as the beginning of the 21st century, the World Health Organization released the “Global Top Ten”, cervical spondylosis is second only to cardiovascular disease, ranking second, and in recent years there is a vague claim that cervical spine problems have surpassed cardiovascular disease, “honored” at the top of the list. So, what is the relationship between “head down” and cervical spondylosis? ”Head down” – the unbearable weight of cervical spine life “Head down” can bring how much burden to the cervical spine? Is it easy to get cervical spondylosis because of “head down”? These questions we can conclude through the following two data: Data one: January 2017, the European Spine Association (EUROSPINE) in its published a statement mentioned: “A person’s head weighs about 5kg, when looking at electronic devices such as cell phones, usually at an angle of 60 °, then due to the role of physical leverage and gravity, a person’s neck muscles will have to bear 25 kg. A person’s neck muscles have to bear the weight of more than 25kg.” Data 2: In April 2020, the China Internet Information Center released the “Statistical Report on the Development Status of China’s Internet”, which reported that as of March 2020, the size of China’s Internet users reached 904 million, the size of cell phone users reached 897 million, and the per capita weekly Internet time was 30.8 hours, an increase of 3.2 hours compared to the end of 2018. If the two figures of 25KG and 30.8 hours are used to estimate, then the cervical spine of nearly 900 million cell phone users in China may bear a burden of up to 770KG every week due to the use of cell phones, which is equivalent to two hundred pounds of “unbearable weight of life” on each person’s neck every day, so the cervical spine problems of Chinese people are becoming more and more prominent and It is not surprising that the trend is towards a younger population with a higher incidence. Symptoms and hazards of cervical spondylosis Neck and back pain, upper limb weakness, finger numbness, lower limb weakness, walking difficulties, dizziness, nausea, vomiting, blurred vision, swallowing difficulties, etc. In serious cases, it may cause stiffness and spasm of the limbs, poor fine motor of both upper limbs, unstable walking of both lower limbs, easy to fall down or even paralysis. Common causes of cervical spondylosis 1, ageing: due to ageing there are different degrees of osteophytes, local ligaments, infrastructure and other soft tissue hypertrophy, calcification; 2, head and neck trauma: cervical spine injuries caused by violence; 3, poor work and living habits: for example, prolonged low-headed ambulatory work, using cell phones, lying down to watch TV; pillow too high, poor sleeping posture, etc. make the cervical joints overworked for a long time, recovery is difficult; 4. Inappropriate sports: such as inversion and somersault with the head and neck as weight-bearing support points can increase the burden on the cervical spine; 5. Disease triggers: such as cervical inflammation, cervical spinal canal congenital stenosis, congenital malformation, etc. can contribute to the appearance of symptoms. Daily cervical spine care 1, correct, improve the work and life of the poor standing, sitting posture, less head down, work 1-2 hours at least once to rest, rest head back, or lying down, so that the cervical spine rest; 2, adjust to improve the sleeping posture: sleeping posture to supine, side lying is appropriate, and prone (lying down) when the head is usually extremely distorted to one side, so that the cervical spine presents a state of tension, easy to damage over time; 3, the appropriate pillow : choose a softer pillow, the height of the pillow can be higher than their fist about 15cm after lying down is appropriate; pillow should be placed on the back of the neck to give the neck to rely on, rather than raising the head to make the neck muscles more fatigue; 4, pay attention to cervical spine warmth, do not get cold. Prevention is better than treatment! The cervical spine as a hub connecting the head and body, is the only channel of nerves and blood vessels, the importance of the human body is self-evident, I hope we can treat it well, develop good habits, prevention, do not wait for the development of “cervical spondylosis” before you start to pay attention.
