Why do girls get mad easy when they are on their periods?

There are many misconceptions around the menstrual cycle and its emotional consequences. While hormonal fluctuations during that time may contribute to a range of physical and emotional effects, it is incorrect to assume that a person becomes irrationally angry solely because of menstruation. Mood swings related to periods vary among individuals. Some experience heightened or negative emotions, but attributing general irritability primarily to menstrual cycles disregards individual variances and perpetuates negative stereotypes about periods and women.
