Many people are busy at work, sitting for 4-5 hours, which is not good for health, but also easy to suffer from lumbar spondylosis. Lumbar spondylosis attack, lower limb numbness, pain, limp, individuals are also accompanied by defecation, urinary disorders, the danger of lumbar spondylosis can not be ignored ah, then, how to prevent lumbar spondylosis office workers? First, the back and stomach, not against the chair. If you lean on the back of the chair, the spinal muscles will be in a stretched state, which over time can easily lead to lumbago. On the contrary, if the back is stretched, not against the back of the chair, not only can prevent the accumulation of abdominal fat, but also stretch the back muscles, which helps focus on work. The second is to walk around more. The office family is trapped in the office every day, sometimes there will be a feeling of suffocation, there is always “suffocating” panic time. Sitting is not conducive to the body, it may be worth walking around more, and activate the muscles and bones, not to long-term ambulation caused by the lumbar and cervical parts of the problem. Third, cushion lumbar protection. Waist put a cushion, can make the waist get effective support, maintain the physiological forward flexion of the lumbar spine, increase body comfort, but the cushion must be placed in the waist, can not be placed on the back of the chest. Cushion is not too thick, to 10 cm thick cushion is good. Fourth, a paper between the knees. Many people sitting always stretched two legs from time to time, which is not only easy to bend back, but also hinder blood circulation. It is best to sit with your legs together, thighs parallel to the ground, and calves at right angles to correct sitting, exercise the inner thigh muscles. Note: Sleeping on a hard bed (ten centimeters below the soft pad) sleeping on a hard bed can reduce the pressure on the intervertebral discs.
