Women's monthly period cycles have a greater influence on mood, behaviour and vital signs than mornings, weekends, or even Christmas, according to international research. The researcher used data from 3.3 million women using a health tracking app and found that menstrual cycles impact our mood 1.4 times more than daily cycles, 3.3 times more than weekly cycles, and even 1.7 times more than Christmas. Women won't be surprised to find that the biggest impact of periods on mood was to make people feel sadder. The researchers also found that the premenstrual decrease in happiness occurs across all 87 countries they looked at, including Australia. The authors stress that their results should not be taken to imply that women are more volatile than men or that the menstrual cycle explains all the variation in women’s mood, behaviour and vital signs.
