A menstrual cup is a flexible, bell-shaped device, typically made from medical-grade silicone, that is folded and inserted into the vagina to collect menstrual fluid. Unlike tampons or pads, it does not absorb the flow but acts as a small receptacle, offering a reusable and long-lasting period management option. Yes, you can safely go swimming while wearing a menstrual cup. This method of period protection is well-suited for swimming in pools, oceans, lakes, or engaging in any water sport.
How the Menstrual Cup Functions Underwater
The effectiveness of a menstrual cup in water is due to the physical mechanics of its internal placement and the resulting seal. When correctly inserted, the cup unfolds and rests against the vaginal walls, creating a secure, leak-proof barrier. This positioning generates a gentle suction, or vacuum seal, which keeps the cup in place and prevents fluid exchange.
This internal seal is strong enough to resist the external pressure of water when swimming or diving. The vacuum prevents pool or ocean water from moving past the rim of the cup and entering the collection chamber, while ensuring that menstrual fluid collected inside the cup cannot leak out.
Because the cup is made from non-absorbent material, usually medical-grade silicone, it does not soak up any surrounding water. This is a significant advantage over products like tampons, which can absorb water along with any dissolved chemicals or microorganisms. The cup remains secure and functional regardless of how long you spend submerged.
Preparation and Post-Swim Care
Proper preparation before entering the water maximizes comfort and security during your swim. It is recommended to empty and rinse your menstrual cup immediately before you put on your swimsuit. This proactive step ensures you start with the maximum capacity available, allowing you to swim for the full 8-to-12-hour wear time without worrying about overflow.
To confirm the cup is positioned correctly, perform a simple check by running a finger around the rim once inserted to ensure it has fully unfolded. You can also gently tug on the stem; if you feel resistance, the seal is properly engaged and the cup is secure for swimming. Always wash your hands thoroughly with soap and water before insertion and removal to maintain hygiene.
After exiting the water, post-swim care is a matter of practical hygiene, especially if you have been in a chlorinated pool or the ocean. While the cup can be worn for its maximum duration, it is advisable to empty and rinse it at your next convenient opportunity. If you are in a public restroom, you can rinse the cup with a small bottle of fresh water over the toilet before reinserting it.
Addressing Water Quality Concerns
The menstrual cup mitigates concerns related to water quality because of its impermeable material. Medical-grade silicone is non-porous and does not absorb fluids, meaning it cannot soak up chlorine from a pool, salt from the ocean, or potential bacteria present in the water. This quality acts as a physical shield, minimizing the risk of introducing external contaminants to the sensitive vaginal environment.
Unlike absorbent products, the cup maintains the natural pH and moisture balance of the vagina, which helps the body’s natural defenses remain intact. Exposure to pool chemicals or saltwater is contained to the exterior of the cup and the vaginal opening. To address any potential residue, simply rinsing the cup with fresh water immediately after your swim is a sufficient measure.
For long-term maintenance, ensure you follow the manufacturer’s instructions for sterilizing the cup, such as boiling it between cycles. This step eliminates any lingering bacteria or chemical traces that may have accumulated. The inherent design of the cup makes it a highly hygienic option for water activities.
