Bad Washing Posture Why does bad washing posture also trigger lumbar synostosis? After a night’s sleep, muscles, ligaments and other soft tissues will become stiff and less flexible in movement, so if you immediately take a hip-bending position to brush your teeth and wash your face, it will put greater pressure on the intervertebral discs. Bending over to carry heavy objects This posture is very common in daily life, and most likely to hurt the waist, especially people who usually rarely carry out physical labor should beware of sudden sprains. The correct posture for carrying heavy objects or picking things up should be: not bending over, by slightly flexing the hip and knee joints to carry. If the legs are straight, excessive bending to pick up things, especially carrying heavy objects is most likely to flash to the waist. Similarly, when cleaning work at home, you should also avoid excessive bending for a long time. Bending over to put on shoes The correct posture should be to put one foot on a small stool in front of you, or to put on shoes in a squatting or sitting position, so as to avoid hurting the lumbar muscles and ligaments. Sneezing and coughing Sudden sneezing or coughing may also strain the back muscles and increase the pressure on the intervertebral discs. In this case, you can avoid lumbar injury by bending your hips and knees slightly.
