1, sleep on your stomach
Sleeping on your stomach is another cause of pelvic kyphosis. When you fall asleep in this sleeping position, your arms are most likely placed in front of your face, which will push your upper body backwards and move your pelvis forward. If a person wants to correct the sleeping position with backward pelvis, then he'd better choose the sleeping position on his back.
2, sedentary
We already know that sedentary is one of the main causes of pelvic kyphosis. Especially sedentary when sitting in an inappropriate position. I'm sure you already know what pelvic obliquity looks like, and you can certainly imagine what this inappropriate sitting posture looks like. Usually, people don't lean back on the back of the chair, but push their hips/pelvis forward. If someone sits in this indecent posture for several hours every day, the hamstring muscles will become shorter, the waist curve will disappear, and it is possible to form pelvic kyphosis.
3. Bad standing posture
Standing with the pelvis backward for a long time will only strengthen bad posture. For example, a person with a backward pelvis usually moves forward when carrying a load on his upper body. For example, when mothers hold their babies, they may swing their waists forward to compensate for the extra weight, instead of standing on a strong waist. For example, some people lean forward and their bellies lean against the workbench to support their weight.
