Apple publishes first menstrual symptom data from women's health study - Android

Meanwhile, the more uncommon symptoms include diarrhea and sleep changes (37 percent each), as well as constipation and nausea (32 percent each). The least tracked symptoms were hot flashes and ovulation pain, which were only reported by 22 percent and 20 percent of the participants, respectively. In addition, Apple and its partners analyzed the reported menstrual symptoms in relation to participants' ages, ethnicities and locations to show similarities and differences across demographics.

The team says it's hoping the study can remove stigma around menstruation and normalize the experience of symptoms so that women, girls and people with menstrual cycles don't get deterred from seeking care for menstrual-related pain. "By building knowledge," the results' announcement reads, "the study is helping to understand factors that make menstruation difficult and isolating for some people. This includes cycle irregularity, extreme pain, or ovarian cysts." Anybody interested in contributing to the study can still do so by downloading the Research app, though they need to be at least 18 years old to participate.
