Why is it that people who frequently lie with their heads down are prone to cervical spondylosis? Each segment of the normal spine has a certain curvature due to the physiological needs of the body, called the physiological curvature. The existence of the physiological curvature of the cervical spine can increase the elasticity of the cervical spine, reduce and cushion the shock of gravity, and prevent damage to the spinal cord and brain. Frequent head-down ambulation can straighten the normal physiological flexion of the cervical spine and cause many other changes in the cervical spine (such as loosening, hyperplasia, muscle tension, etc.), which can stimulate the surrounding nerves or blood vessels and lead to cervical spine pain. How to rehabilitate the cervical spine during sleep? Each person has 1/3 of his life spent in sleep; a pillow closely suited to the physiological curvature of the cervical spine, can make work, study, life after a day of you, in the sleep to lift the cervical muscles, ligament fatigue. According to ergonomics, the shape of the pillow, with the middle low, both ends of the high yuan Bao shape is most suitable for the cervical physiological curvature. This pillow can be used to maintain the physiological curvature of the cervical spine by using the front projection. How does a laptop hurt your cervical spine? Laptops are seriously flawed in ergonomics, the distance between the screen and the keyboard is too close, stiffening the neck and looking down at the screen may cause neck muscle damage; lifting the machine to a position suitable for the eyes may in turn cause shoulder and arm muscle strain. At present, a variety of related pathologies have gradually emerged in the early users of laptops. The correct way to prevent this is to pad the laptop while using an external traditional keyboard. At the same time, it is important to get up and move around frequently, especially to do cervical flexion and extension rotation activities. What to save your cervical spine, cervical spondylosis is important to prevent! There is no effective treatment for cervical spondylosis in the medical community, and in general cervical spondylosis focuses on prevention. Although cervical spondylosis occurs mostly in middle-aged and old age, the pathological process often begins in adolescence. Especially in the current workforce, the age of onset of cervical spondylosis has been greatly advanced. For the causative factors of cervical spondylosis – strain, pillow, poor sleeping posture, improper pillow, wind and cold, head and neck trauma, etc. – if we can take effective preventive measures as early as possible, we can reduce the incidence of cervical spondylosis or delay its onset.
