The team of car people is getting bigger and bigger, and it is becoming more and more common to use the car as a substitute, especially for the younger generation. Long-distance travel, self-driving figure is convenient, free, in the past Mid-Autumn Festival holiday, driving vehicles and family members together to enjoy the joy of the journey, is how happy. The convenience of the vehicle can not be denied, but there are many hidden dangers of long-distance driving, the lighter may induce disease, the more serious lead to car accidents, life-threatening. The lumbar spine is the most easily damaged part of long-distance driving The load on the lumbar spine when sitting is two times that of standing, and long-distance driving requires drivers to sit and stand for a long time, which is bound to put a greater burden on the lumbar spine. Possible problems with the lumbar spine include: lumbar muscle strain: lumbar muscles are important tissue structures that support the human body, long-distance driving people, due to a tense sitting posture, less activity, local muscle tissue is prone to ischemic changes, and then muscle spasms, lumbago, long periods of time without improvement will lead to muscle strain. Intervertebral disc herniation: the intervertebral disc is located between the vertebrae of our body, is connected to the adjacent two pushes the body of the fibrocartilage disc, external for the fiber ring, composed of numerous layers of fibrocartilage ring, tough and elastic: internal for the nucleus pulposus, white and elastic gel, tough and elastic, with “elastic cushion-like” cushioning role. It assists our spine in all directions of movement. In layman’s terms, the role of our intervertebral disc is similar to that of a shock absorber, providing a shock-absorbing effect on the spine. A lumbar disc herniation is a degenerative change in the lumbar intervertebral disc. Under the action of external forces. The fibrous ring is partially or completely ruptured, together with the nucleus pulposus, and expands outward. It causes back pain caused by irritation or compression of nerve roots, blood vessels or spinal cord and other tissues. And accompanied by sciatic nerve radiating pain and other symptoms characterized by a kind of vertebral disc tissue lesions. Poor sitting posture is the main cause of this disease in drivers. Our lumbar spine in a normal state has a natural bend, it is because of the existence of this physiological curvature, the lumbar spine can move freely, the lumbar gap is wide in front and narrow in the back, the intervertebral disc is not easy to displace. Long hours of driving, the driver’s lumbar spine will be in flexion for a long time, the lumbar spine gap is narrow and wide for a long time, the disc will easily protrude backwards, resulting in disc herniation. In addition, the lumbar vertebrae ask for disc herniation also has a relationship with the bumps in the driving process. If the car damping is not good, or the road is seriously uneven, it will intensify the degree of vehicle bumps, the resulting bumps will increase the stress on the intervertebral discs, while the lumbar spine has to withstand a certain pressure, the increase in pressure will make the intervertebral discs due to deformation and lesions, it is easy to suffer from “lumbar disc herniation, lumbar spinal stenosis” and other diseases. Suggestions: try to avoid driving, long-distance travel, choose trains, airplanes and other public transport. And if you really need to drive, first of all, pay attention to the posture of the waist, it is best to make the angle between the backrest and the seat is 90 degrees, the back of the waist has a cushion of about 10 cm high, so that the lumbar spine is in a natural physiological convex state; secondly, continuous driving does not exceed 2 hours, during the midway break appropriate activities of the limbs, lumbar extension, lateral flexion activities, repeated several times; finally, when the road conditions are not good, slow down and drive smoothly. Avoid violent bumps. If sudden pain in the back and legs occurs during driving, it is recommended to stop nearby or in the service area and change the driver rather than continue driving. The numbness and weakness of the lower limbs caused by lumbar disc herniation may make the driver unable to effectively control the gas pedal and brake, resulting in an accident. Fatigue driving is another important safety hazard of long-distance driving Fatigue driving refers to the decline in response level after a period of driving, which is manifested in distraction and, in severe cases, drowsiness, resulting in driving operation errors or loss of driving ability. The cause: long-distance driving in the face of monotonous highway, lack of visual stimulation, if sleep deprivation, very easy to fatigue, drowsiness, and the general driver lack of awareness of their own fatigue, even if they know they are fatigued, but they overestimate their ability to resist fatigue, often wait until they feel really can not stop, and at this time they have They often wait until they feel they can’t stop, and by then they have already had a brief drowsiness, and a serious traffic accident may happen in this instant. Some people under the age of 30 with brief apnea are most likely to be involved in a serious traffic accident after a night shift, and the most likely time for an accident is the early morning and afternoon. Prevention or intervention of fatigue driving is an effective measure to reduce traffic accidents. Suggestions: first of all, ensure sufficient sleep, before deciding to drive long distance, at least 8 hours of sleep the night before; long-distance driving, about 1 hour of continuous driving, it is best to stop and rest for 5 minutes; best not to drive long distance alone, language communication is also one of the measures to avoid fatigue. If there is already a state of fatigue, consider supplementing refreshing drinks, such as Red Bull; also available wind oil, cool oil applied to the temple area; listen to some of their familiar songs, try to avoid listening to unfamiliar songs and turn up the sound, which will reduce the driver’s responsiveness; in fact, whether it is spinal protection or prevention of driving fatigue, good physical condition is a prerequisite. In addition to driving, should strengthen exercise, such as running, swimming, brisk walking and weight exercise, etc., to improve physical strength, endurance and muscle strength of the lower back, the same can prevent the hidden dangers caused by long-distance driving.
