The correct position for people with anterior pelvic tilt to sleep is supine, and it is not recommended to sleep on the side or prone for a long period of time. Sleeping in the supine position can better relax the muscles around the lumbar spine and the pelvis, which can reduce the tendency of anterior pelvic tilt to a certain extent. If you keep sleeping on your side in the same direction for a long time, it will make the force on both sides of the pelvis uneven, and the sacroiliac joints may be dislocated, so it is not recommended to sleep in this position for a long time. It is also not recommended to sleep in a prone position. In addition, people with anterior pelvic tilt can place a pillow of about 10 centimeters in height under the knee on the basis of lying down, which is conducive to regulating the balance of the joints. At the same time, it is important to maintain correct sitting and standing postures in daily life. If symptoms of anterior pelvic tilt appear, you should go to the hospital in time, complete the relevant examinations, make a clear diagnosis and then follow the doctor’s instructions for treatment, so as to avoid delaying the condition.
