Sitting position, the lumbar spine to withstand the load is twice as long as when standing, whether it is usually a long time to drive or long-distance driving, drivers will be sitting for a longer period of time, which will inevitably bring a greater burden on the lumbar spine, which may lead to or aggravate the following problems. Lumbar muscle strain: lumbar muscle is an important tissue structure to support the human body, long-distance driving for a long time in a tense sitting position, less activity, the local muscle tissue is prone to ischemic changes, which leads to muscle spasms, lumbago, long time not to change the sitting position will bring muscle strain. Lumbar disc herniation: The intervertebral disc is located between the vertebrae of the human body, and its role is similar to a shock absorber for the spine shock. Lumbar disc herniation refers to the lumbar intervertebral disc degeneration, under the action of external forces, the fibrous annulus ruptured partially or completely, together with the nucleus pulposus and outward expansion, irritation or compression of nerve roots, blood vessels or spinal cord and other tissues, resulting in low back pain. Bad sitting posture is the main reason why drivers suffer from this disease human lumbar spine in the normal state has a natural curvature, it is because of the existence of this physiological curvature, the lumbar spine can move freely, lumbar spine gap before the wide after the narrowing of the intervertebral discs are not easy to dislocation. Driving for a long time, the driver’s lumbar spine will be in a long time in the flexion position, lumbar spine clearance for a long time before the narrow back wide, the disc is easy to backward protrusion, resulting in lumbar disc herniation. Lumbar disc herniation is also related to the bumps in the driving process If the car is not well damped, or the road is not level, it will exacerbate the degree of vehicle bumps. Bumps will make the intervertebral discs are subject to increased stress, so that the lumbar spine to withstand a certain amount of pressure, increased pressure will make the intervertebral discs due to deformation and lesions, the driver is very susceptible to lumbar intervertebral disc herniation, lumbar spinal stenosis and other diseases. Waist to put cushion In view of the above problems may occur, it is recommended that people try to avoid driving long-distance travel, if you really need to drive, first of all, should pay attention to the posture of the lumbar region, it is best to make the angle of the backrest and the seat was 90 degrees, the back of the waist pad a cushion of about 10 centimeters high, so that the lumbar vertebrae are in the natural state of the front convex. Secondly, do not drive continuously for more than two hours, midway rest period appropriate activities of the limbs, lumbar stretching, lateral flexion activities, repeated many times. Finally, when the road conditions are not good, slow down and drive smoothly to avoid violent bumps. If sudden back and leg pain occurs during driving, it is recommended to stop nearby or go to the nearest service area to stop and change the driver. Because lumbar disc herniation attack will lead to lower limb numbness, weakness, may make the driver can not effectively control the gas pedal, brakes, causing accidents. Driving a long-distance car is most afraid of fatigue Drivers long-distance driving in the face of monotonous highway, the lack of visual stimulation, if sleep deprivation, very easy to fatigue, drowsiness, and the general lack of drivers on their own fatigue awareness, even if you know that they are already very fatigued, but also overestimated their own ability to resist fatigue, very likely to lead to traffic accidents. Long-distance driving the night before to ensure that at least 8 hours of sleep long-distance driving on the way, continuous driving for about 1 hour, it is best to stop and rest for 5 minutes; it is best not to drive alone long-distance, language exchange is also one of the measures to avoid fatigue. If you already feel tired, you can drink refreshing drinks, can also be used in the wind oil, cool oil applied to the temples, you can also listen to some of their own familiar songs, try to avoid listening to unfamiliar songs and open the sound is very large, which will reduce the driver’s ability to respond.
