Today’s ubiquitous and omnipotent computer has gone through more than 50 springs and autumns. Since the first generation of computers was introduced, it has had an extremely important impact on human production activities and social activities, and has developed rapidly with a strong vitality. With the progress of science and technology, the development of computers has entered a rapid and new era, has developed from a single function and large size to a complex function, tiny size, fashionable and convenient, more intelligent. The application of computers has penetrated into every aspect of our lives and work. While computers bring us convenience, they also pose a potential threat to our health. Now the white-collar work is generally “a computer on and off, a day has passed”, now young white-collar work on the computer at work, after work and busy playing games online, chatting and relaxing, in order to work and study life, a long time to stretch the neck, head down and look at the screen, which caused damage to the neck muscles. If the operating posture is not standardized, but also to accelerate the onset of spinal disorders, many people therefore unknowingly produced cervical and lumbar injuries and other diseases. For urban white-collar workers, due to busy work, often overtime, even if the cervical spine is not comfortable, it is often difficult to get more protection, which requires us to protect the cervical spine in our daily work subconsciously. The human cervical spine mainly supports the head, and its range of motion is large. Studies have shown that when people lift their chests and heads normally, the neck can perfectly support the weight of the head, and for every 1-2 cm of head forward, the neck has to support the weight of one more head. When the head is lowered for a long time, the cervical spine is in a flexed position for a long time, the neck muscles are under tension, the muscles and ligaments at the back of the neck are strained and damaged for a long time, and the front edge of the vertebral body is worn and proliferated due to the narrowing of the gap, which will produce a series of symptoms of cervical spondylosis. The danger of cervical spondylosis is self-evident, so we absolutely can not ignore it, must not sit still, do not cause big problems because of laziness. Here are a few simple and easy-to-use prevention and treatment methods to defend our cervical spine health. 1, use the book to cushion the computer and elevate the monitor. Research has found that when the eyes are looking straight ahead, the human cervical spine pressure is the smallest, with a laptop computer work of white-collar family is best to pad a few books under the computer to raise the monitor, so as to adjust from the previous low work to work with the head up, to reduce the probability of cervical spondylosis at the source. We can master the thickness of the book ourselves, master a principle, as long as we sit straight, to achieve the basic flush with the upper edge of the monitor can be. After raising the display, it is best to use an external traditional keyboard, so as to reduce the strain on the wrist after the laptop is raised, the effect is better. 2, in making up for the ergonomic deficiencies of the laptop, after working for a period of time or to stand up and rest for a moment, it is best to do the activities of the neck and shoulders every two hours or so, looking out of the window, through the neck muscles stretching, stimulating the arteries of the neck, so that the neck and shoulders blood flow smoothly, to speed up the absorption of local sterile inflammation, lifting the neck and shoulders caused by the use of laptop It also helps to relieve the tension and discomfort of the neck and shoulder muscles caused by the use of laptops and restores the softness and elasticity of the muscle ligaments. Take about ten minutes to do more neck and shoulder health care gymnastics, the specific operation method can refer to my other popular science articles, I believe it will help you. 3, the summer is coming, the widespread use of air conditioning is making people suffer from cold and wet opportunities to increase. Chinese medicine believes that long-term blowing air conditioning is prone to wind and cold invasion of the body, resulting in the human qi and blood, the so-called “not pass is pain”, neck and shoulder muscle pain and soreness, and eventually lead to cervical strain injury. Therefore, we remind everyone that the summer do not adjust the air conditioning temperature is too low, generally about 26 ℃ is appropriate. In the air-conditioned room with low temperature, you should find a scarf to put around the neck, so as to avoid the cold neck and eliminate the triggering factors of cervical spondylosis, so as not to cause or aggravate cervical spondylosis by cold neck. Keeping the neck warm not only avoids neck fatigue, but also prevents the blood vessels in the head and neck from contracting due to the cold, which slows down the blood circulation in the brain. 4, the last point, or to recommend that we participate in more outdoor physical exercise, if there are conditions can also choose certain sports, to enhance muscle strength and strengthen the body exercise, such as swimming, playing badminton, etc.. ”Details determine health”, on weekdays, pay attention to cervical spine health care, to develop good work and life habits, to better enjoy a healthy life.
