At the same time, sedentary will also make the pelvis and sacroiliac joints for a long time weight, lack of activity in the waist, blood is easy to stagnate and affect the blood circulation of the lower limbs, numbness in the legs, and over time can lead to muscle atrophy. 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 back pain. First of all, to choose a desk and chair suitable for their height and physique. 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 posture 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 office “groveling”, the muscles of various parts of the body, especially the lumbar muscles, it is easy to fatigue, so the best sitting posture is to raise the head and body to keep a basic 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, office workers must strengthen their own protection, in the sitting posture should be straight, tucked in, 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 vertebrae in a long-term position of being compressed. In addition, for those who work all day in the office of white-collar workers, some habitual actions, such as hooking the head on the keyboard to type, or the phone handset between the shoulders and head to call, should be changed – to often change the posture, every once in a while to take a break, even if only to pour a glass of water in the office, a little activity It is also good. Again, to strengthen the lower back activities. 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, see a stitch to entertain, “leisure time” is not too idle, always maintain a good and healthy state of mind, but also to a certain extent to prevent 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 is not smooth, coupled with the lack of exercise, the waist and back hip blood circulation stagnation, 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 ℃ is appropriate. If you can take time off 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.
