Long time sedentary office, less activity, straight back, lumbar discs and interspinous ligaments for a long time in a state of tension, stiffness, over time it is easy to make the back pain, stiffness, can not lie on their backs and turn around. At the same time, the sedentary will also make the pelvis and sacroiliac joints for a long time weight, the lack of activity in the waist, blood and gas is easy to stagnate in the waist and thus appear stagnant blood stasis, affecting blood circulation in the lower limbs, and numbness in the legs, which can lead to muscle atrophy over time. In this case, muscle stiffness, a little activity may sprain or cause other injuries, and lead to back pain. In addition, the office staff work, sitting chair is not appropriate or chair and desk height ratio is not coordinated, their own poor sitting posture or bad posture for too long, the lack of low back exercise, etc., can also trigger the sedentary office staff back pain. In fact, as long as there are good working habits, even sedentary office can also avoid lumbago. First of all, to choose a desk and chair suitable for their height and posture. Prevention of back pain in the office should first start with the choice of desks and chairs, office workers must choose to meet the principles of human biomechanics, in line with their height and body shape of the desk and chair. If possible, it is best to choose a chair with armrests in order to support the elbow and relieve the pressure on the waist. Second, to maintain the correct sitting posture. Many people never care about their sitting posture, in fact, due to poor sitting posture is likely to lead to lumbar health problems, for example, if you sit in the office if you grovel, the muscles of various parts of the body, especially the lumbar muscles are easy to fatigue, so the best sitting posture is to raise the head and body basically keep a straight line; if the head is too far forward, the neck and upper back muscles will be tense, but also easy to produce fatigue . In other words, the office staff must strengthen their own protection, in the sitting posture should be straight upper body, tuck in the abdomen, jaw slightly closed, the two lower limbs together, you can also put an object under the desk can cushion the feet, so that the knee joint slightly higher than the hip. And after working for a period of time, adjust their work position as appropriate, should not let the lumbar spine in a long-term position of compression. In addition, for those who work all day in the office of white-collar workers, some habitual actions, such as hooking the head amble on the keyboard to type, or the phone handset between the shoulders and head to call, should be changed often to change the posture, every once in a while to take a break, even if it is only in the office to pour a glass of water, slightly active activities. Again, to strengthen the activities of the lower back. Office workers even in the busiest time should also take a little time to leave the desk, do back extension, left and right rotation and other lumbar activities. This can prevent and relieve low back pain. People who have plenty of time can regularly carry out exercise activities every day to strengthen the muscle strength of the lower back, which not only prevents low back pain, but also helps to exercise the body. Finally, learn to relieve work stress. In reality, there are many people whose low back pain is not due to a physical lesion, but purely mental in nature. If you can spread out the pressure, so that the “busy time” is not too busy, stitching entertainment, “leisure time” is not too idle, always maintain a good and healthy state of mind, but also from a certain degree of prevention of back pain. In addition, if you live in an air-conditioned office in the summer, the cold wind of the air conditioner is easy to stagnate the blood, the pulse channel is not smooth, coupled with the lack of exercise, the waist and back hip meridians blocked, there will naturally be a sense of back pain. Therefore, the air conditioning temperature should not be too low, the temperature difference between indoor and outdoor does not exceed 5 to 7 degrees Celsius is appropriate. If you can take time out in the office to do some exercises at the right time and in the right place, you can also relieve back pain. People who do not have back pain can also reduce the chances of developing back diseases.
