Menstruation, despite being a healthy and fundamental bodily process, is a topic often buried in fear and shame, and its discussion is even taboo in many societies. But a worldwide effort to bring conversations about menstruation and menstrual health into the open is now firmly underway. Period Matters carries this important endeavour forward by bringing together a breadth of perspectives from well-known figures as well as those whose voices are missing from the mainstream. Essays, artwork, stories and poems from policymakers, entrepreneurs, artists, academics, activists, as well as interviews with those at the margins, such as the homeless and those living with disabilities, explore myriad aspects of how menstruation is experienced in South Asia.
