The most common reason for insomnia in the days before menstruation is that the hormone levels in the body drop a few days before the onset of menstruation, so it affects women’s sleep, and a series of other discomforts may also occur, often called premenstrual syndrome. Some women may experience facial acne, while others may experience mild edema of the lower extremities, as well as headaches, irritability and other symptoms. Generally speaking, if a woman has insomnia a few days before her period, she can consider seeking Chinese medicine to regulate the treatment, and she can also consider taking glutamine specifically for treatment.
