Factors affecting lumbar health

1. Incorrect force applied to waist.

In daily life, we often encounter some situations that need to bend over to carry heavy objects. Because of long-term inactivity, the strength of lumbar muscles is weak. If we bend down and lift heavy objects directly, the weight will directly act on the waist, which may cause waist injury. It is recommended to squat down before lifting heavy objects every day. The lower limbs and waist can share the weight and protect the lumbar spine.

2. Long-term incorrect sitting posture

Now most of the work belongs to shift duty, and the team leader works at his desk for a long time. Bad posture will make the whole spine in an unnatural and uncoordinated bending deformation state, and the ligaments and muscles of the whole spine are in an abnormal load state and an ischemic and anoxic environment. If you don't pay attention to the activities of the waist, it will cause lumbar injury and lumbar spondylosis over time.
