The benefits of exercising during your period, backed by research. The chapter explains how regular aerobic activity has been linked to fewer and less severe menstrual symptoms, and challenges the outdated idea that menstruation makes the body weak. It covers the wider health benefits of exercise, such as weight management and a stronger heart, and how working out can raise serotonin and dopamine, improving mood and energy during menstruation. A final page looks at bloating, a common period symptom, explaining how exercise helps digestion and circulation and citing a study on how much aerobic exercise improved bloating symptoms.
