Menstruation and Swimming: What You Need to Know

When in the water, the hydrostatic pressure may temporarily prevent or reduce menstrual flow, due to constriction of blood vessels as well as decreased intra-abdominal pressure when submerged. However, menstrual blood can still be released when you get out of the water or are no longer fully submerged. To manage your period while swimming, you can use tampons or other menstrual products specifically designed for water activities.
