Periods are a fact of life for roughly half the population, yet discussions of the menstrual cycle are often shrouded in confusion and embarrassment. Part of the Q&A Health Guides series, this book offers a broad introduction to the menstrual cycle-what it is; why it exists and how it changes over time; what's normal; when you may want to see a doctor; and which products, medications, and activities can make "that time of the month" a more pleasant experience. Periods: Your Questions Answered addresses more than 30 menstruation-related topics in a way that is engaging and accessible to young readers. Biology and physiology are explained in easy-to-understand language and blended seamlessly with scientifically backed recommendations readers can use in their own lives. Augmenting the main text, a collection of 5 case studies illustrate key concepts and issues through relatable stories and insightful recommendations. The common misconceptions section at the beginning of the volume dispels 5 long-standing myths about the menstrual cycle, directing readers to additional information in the text. The glossary defines terms that may be unfamiliar to readers, while the directory of resources curates a list of the most useful books, websites, and other materials. Finally, whether they're looking for more information about this subject or any other health-related topic, readers can turn to the Guide to Health Literacy section for practical tools and strategies for finding, evaluating, and using credible sources of health information both on and off the Internet.
