The driving habits that old drivers should pay attention to
4hw.com.cn: professional drivers, taxi drivers and long-distance bus drivers have the most say in driving occupational diseases. Apart from eating and sleeping, they spend other time in the driver's seat every day. In addition, their driving habits are not good, so they come to us with lumbocrural diseases. Today, Xiaobian checked the occupational diseases caused by some of the drivers' worst driving habits.
I. wrong driving and sitting position
Some drivers like to adjust their seats forward or backward as much as possible. In fact, they are not in the right driving posture. If the seat is too far forward, the muscles of the limbs and waist are in a state of continuous tension. If the seat is in this position for a long time, it is easy to cause the ache of the muscles of the limbs and waist back; if the seat is too far back, it is easy to cause the herniation of the intervertebral disc, and the muscles of the waist back are in a state of stretching for a long time, which is easy to cause the fatigue injury of the muscles.
In fact, it is not difficult to master the correct driving and sitting posture. The seat surface should be slightly tilted back, and the seat back should be adjusted to form an angle of 100-110 degrees with the seat surface (the simple method is to adjust the headrest of the seat back to the distance of 2-3 punches from the occipital bone in the case of vertical sitting posture), while the fore-and-aft adjustment of the seat should be related to the height and body shape of the driver, generally holding the steering wheel with both upper limbs, and bending the elbow joint at 50-60 degrees; It is better to put the lower limbs on the pedals naturally and the knee joint flexes naturally at about 60 degrees. The buttocks should be as far back as possible, and a 2-3 inch thick lumbar pad can be placed at the waist, which not only keeps the normal physiological curvature of lumbar lordosis, but also has a certain supporting effect on the waist.
II. Air conditioner temperature is too low
The low temperature makes the local blood vessels and muscles in the state of contraction, the local blood flow becomes less and the flow velocity slows down, all kinds of inflammatory factors are locally accumulated among the tissues, which are not easy to be removed, leading to aseptic inflammation of soft tissues such as synovitis, ligament inflammation and fasciitis, resulting in pain symptoms, especially at the time of seasonal replacement, the symptoms of low back pain are more likely to occur; at the same time, the low temperature makes the pores of the skin shrink and sweat The decrease of liquid elimination is not conducive to the discharge of harmful substances in the body.
Therefore, when driving, do not covet the coolness for a while and adjust the air conditioning temperature too low. It is more conducive to health to properly open windows for ventilation or control the temperature inside and outside the vehicle within 5 ℃. If you have symptoms of low back pain, you can carry out physical therapy of low back hot compress. At the same time, you can wear the waist circumference when driving to protect the lumbar support, and have the effect of local warmth preservation.
III. frequent emergency braking
In case of sudden braking during driving, inertia and forward impulse force will make the driver's body rush forward, and then the cervical and lumbar vertebrae will buckle forward and then spring back to their original position. In the long run, it is easy to form 'swing injury'. At this time, the stable structure of the stable lumbar vertebrae plays a role in limiting the relative movement of the lumbar vertebrae. However, if the frequent and repeated emergency braking, the stable structure will eventually be fatigued, Cause lumbar muscle strain, fasciitis, even lumbar disc herniation and lumbar spondylolisthesis.
Therefore, forming good driving habits and driving steadily can not only improve driving safety, but also effectively reduce the load on the waist. Of course, in view of the relatively narrow internal space of the general private car, as well as the high tension of the body and mind when driving, it is recommended that the continuous driving should not exceed two hours, and the rest should be 10 minutes every other hour.
IV. automobile diseases and causes
1. Due to the long-term closure of the car, the air is not circulating, and harmful gases cannot be discharged in time. Even if the benzene content does not meet the carcinogenic standard, it will increase respiratory diseases such as asthma and chronic bronchitis.
2. People who drive for a long time will affect blood circulation due to sitting for a long time, resulting in congestion of anus, and constipation due to failure to defecate in time.
3. When the car is started, the driver is in a state of vibration with the car. At this time, the pressure in the intervertebral disc is relatively high, and the pressure of sitting with bent back is greater than that of sitting with straight body. In this way, it is easy to cause the lumbar disc to protrude in the long run.
4. Because the driver's arm is suspended for a long time, the vibration of the car and steering wheel will affect the arm and fingers of the human body, resulting in the injury of the nerves around the wrist, mainly manifested as numbness of the palm, pain of the wrist joint and other phenomena.
V. how to prevent and treat 'automobile disease'
1. Prevent driving for a long time. Stop for a rest when driving for about two hours in a row, get out of the car and stretch your waist, and do some extensible sports.
2. When stopping driving, turn your wrist more, clench your fist more, and rub your fingers to relieve hand fatigue.
3. When using the air conditioner in the car, do not only use the internal circulation, occasionally change the external circulation, and properly maintain the air conditioner in the car, and change the additives regularly.
4. Small plants can be placed in the car. The newly purchased interior or supplies should be placed outside or cleaned before being placed in the car. In addition, some negative ion releasers can be installed in the vehicle to maintain the air flow in the vehicle.
