Many office workers are accustomed to lying on the table after lunch or lying on the sofa morning sleep, think this can best relieve the fatigue brought about by a busy morning, sleep can better start the afternoon work. But in fact, you think you can relax the spirit of sleep are not suitable, these sleeping methods not only can not completely relief, but will bring a lot of harm to the body, including the spine. For example, take their arms as a pillow to sleep, left and right crooked head to sleep, or the forehead on the arm to sleep, these positions will make the cervical and lumbar spine hyperflexion, greatly exceeded their normal physiological curvature, if you keep these bad posture for a long time, will make the cervical and lumbar spine muscle tension, resulting in neck, back and lumbar pain, serious will also lead to cervical disc or lumbar disc protrusion, triggering disc herniation. In addition, often sleep on the table for a long time with the arms on the pillow, but also easy to cause the brain blood supply, oxygen supply is insufficient, and even promote brain infarction. Because the blood to go up to the brain, must pass through the cervical spine blood vessels, when the cervical vertebrae are squeezed because of excessive bending, the intervertebral foramen narrowed, so it causes the blood flow of the blood vessels in the intervertebral foramen is not smooth, can not supply the brain with enough blood. This will lead to the brain due to ischemia and lack of oxygen and make people appear dizzy and weak, especially those who are cardiovascular and cerebrovascular is not healthy, it is easy to have a sudden brain infarction. There are some office workers like to lie in the sofa morning sleep, such a posture seems comfortable, in fact, the damage to the spine is not small. Sofa is usually softer, people lying on it, the cervical spine, thoracic spine and lumbar spine normal physiological curvature will change, especially the head pillow on the armrest of the sofa to sleep, cervical spine for a long time to maintain an overly forward-flexed posture, not only easy to pillow, but also cause cervical spine strain, obstructing the cervical artery blood supply, easy to appear headache, nausea and other symptoms. In addition, we know that under normal circumstances, people always turn over when sleeping to change positions. From the point of view of health care spine, this unconscious turning action, help to correct mild misalignment of the small joints of the spine, and reduce the pressure caused by long hours of sitting on the lumbar discs. But the sofa is too soft, and space is small, people sleep on it is like “trapped” in the same, it is difficult to turn over at will, so that the back and legs and feet are fixed in a rigid state, not only is not conducive to the correction of those mildly misaligned small joints of the spine, but will make these small joints misaligned degree of aggravation, over time it is easy to cause spinal lesions. This shows that office workers lying on the table and lying on the sofa morning nap practice, are not desirable. In fact, nap is not the only way to relieve fatigue, if you are not particularly sleepy, it is best to get out of the office to walk around, both to breathe fresh air, but also to effectively reduce the degree of fatigue of the spine. If overworked, especially want to take a nap, then it is best to lean on a chair with a backrest, pillow a small cushion in the neck as a pillow, a nap can be. But sleep time should not be too long, sleep 30 minutes is enough, because the sleep time is too long more easily fatigued, but affect the efficiency of the afternoon.
