Generally speaking, women are not advised to wear corsets to sleep at night, just as women are not advised to wear bras to sleep at night. At night, the human body is in a state of complete relaxation. It's best not to put any constraints on your body. In particular, some women's corsets are very tight, which may oppress the tissues of the body and affect blood circulation, which is not conducive to the normal metabolism of the body. If the pelvic cavity or waist is tightened too tightly, it may also affect the blood circulation of the pelvic cavity, which may easily lead to pelvic blood stasis and gynecological diseases such as dysmenorrhea or backache.
