Why read it?

1 author picked Once a Month as one of their favorite books. Why do they recommend it?

Dr. Dalton is the OG researcher who invented the phrase PMS and conducted the first studies on PMDD. Once a Month lays out her body of research in layperson terms. A bestseller when it was first published, much of it is still relevant and fresh today.

I particularly enjoyed her chapter on how the menstrual cycle impacted student behavior from grades to tidiness—not everyone had the same patterns, but most people saw their behavior change in some way over the course of their cycle. If only someone had told me that years ago!
