Should I practice when I’m on day 1 of my period?
There are no hard-and-fast rules—better to discover for yourself what best serves you. If you do choose to do yoga, skip inversions. During your cycle, your body’s energy is naturally moving downward, and inversions reverse that movement. There is a quietness in our bodies during the menstrual cycle; forward bends, gentle twists, and supported backbends are intelligent choices for your moon days, as they encourage that exquisite interior inquiry.
