Usually the dizziness of patients playing 3D games is mainly due to the relatively weak function of the vestibular system that regulates body balance, brain fatigue, cervical spondylosis, etc. can also cause similar symptoms, but it is relatively rare. The body balance and orientation function of human body is accomplished by vision, deep sense and vestibular system together, through vision to determine the orientation of surrounding objects, the relationship between the body and surrounding objects, and then further through deep sense to obtain their own position and motion sensation, at this time the vestibular system can perceive the spatial position of the body, and finally achieve the maintenance of body balance. Playing 3D games is a dynamic process, in which patients also need to rely on vision, deep sensation and vestibular sensation to maintain their posture. Patients with relatively weak vestibular system can have contradictory information in their vision, which is manifested as misorientation of space. On the basis of this contradictory information and the vestibular system of the vestibular endings, pontocerebellum, cerebellum, cortex and other neurological nuclei areas do not match the original pattern and produce conflicts, which can cause patients to vertigo. At the same time, patients who play 3D games have a high concentration of attention for a long time and their brains cannot get enough rest, which can cause their bodies to enter a state of fatigue and thus cause dizziness. In addition, patients who play 3D games for a long time to maintain the same posture, may cause cervical spondylosis attack, when serious can compress the cerebral blood vessels cause cerebral blood supply deficiency, that is, patients can be manifested as dizziness. Therefore, play 3D games dizzy patients should stop the game in time, and keep the room air circulation, moderate breathing fresh air and pay attention to the eyes, brain rest, if the cervical spondylosis patients can be treated by traction, physical therapy and other means.
