Sleeping like this for a long time can easily damage the uterus

Wang Jing, a professor of health preservation at the China Academy of Chinese Medical Sciences, said: "Sleeping postures are nothing more than lying on your back, lying on your stomach, and lying on your side. Sleep health preservation emphasizes not to stay in one posture for too long."

First of all, the most unfavorable sleeping position for women’s breasts is sleeping on your stomach. Lying prone is the most unfavorable to health. This posture can easily put pressure on the chest. For growing girls, this posture will also affect the development of the chest cage and breasts, so try to avoid it.

Secondly, sleeping in the supine position for a long time will have an adverse effect on women's uterus. This is because in the normal anatomy of the female reproductive system, the position of the uterus should be in an anteriorly bent and anteflexed position, while sleeping in the supine position can easily lead to a posteriorly positioned uterus. When a woman sleeps in a supine position, the longitudinal axis of the uterus is approximately at a 45-degree angle to the bed surface. In addition, the weight of urine in the bladder will press the uterus backwards, damaging the ligaments that fix the uterus, thus causing a posterior uterus. A posterior uterus can easily lead to problems such as dysmenorrhea and heavy menstrual flow, and in severe cases it can even lead to infertility. In addition, if pregnant women sleep in a supine position for a long time, the increased weight of the uterus may compress the inferior vena cava, affecting the return of blood in the inferior vena cava.

For women, the most natural sleeping position is the side-lying position. Lying on the right side will not compress the heart or affect gastrointestinal motility, and is generally better than lying on the left side. Professor Wang Jing emphasized that most people will change their sleeping positions several times every night. Even if you lie on your right side, if you maintain this position for a long time, it will have an adverse effect on your shoulder joint.
