In a society where menstruation is still considered taboo, it is necessary to know the seriousness of the problem. In Japan, about 8 million women suffer from dysmenorrhea. Do you think of menstruation as "a period where blood flows and you feel tired once a month"? Although menstruation is said to occur once a month, many women experience a period of about three weeks of discomfort per month due to hormonal influences. In other words, the period when your physical condition is stable and not affected by menstruation is only one week per month. The suffering of women is not limited to stomach pain, but also headaches, dizziness, drowsiness, overeating, negative thoughts, and various other problems. From an economic perspective, menstrual disorders affect work performance in women, and the labor loss is estimated to be more than 490 billion yen per year. In a society where it is considered taboo and sometimes considered an "excuse," we must realize the seriousness of the problem.
