Summary
This study tested the Cycle Syncing Method, which uses an app to guide diet, exercise, and daily activities based on your menstrual cycle phase. Sixty women aged 22 to 42 with regular cycles but bothersome symptoms participated fully online for 12 weeks. The goal was to see if this approach could reduce period-related discomfort and help balance hormones naturally.
