Many individuals wonder if swimming during menstruation causes their period to stop. This common question often arises from observations made while submerged in water, leading to a belief that water somehow halts the natural biological process. This article explores the science behind why menstrual flow appears to change in water and provides practical advice for comfortable swimming during your period.
Does Water Stop Your Period?
Water does not stop your period. The biological process of menstruation, which involves the shedding of the uterine lining, continues regardless of whether you are in water or on land. While your flow may seem to cease when you enter a pool or the ocean, this perception is due to external factors rather than a change in your body’s internal functions. Menstrual fluid is still being released internally.
The Science of Menstrual Flow in Water
The apparent reduction or cessation of menstrual flow in water is primarily due to hydrostatic pressure. When submerged, water exerts a gentle, outward pressure on your body, including the vaginal area. This external pressure counteracts the force of gravity that typically aids menstrual blood flow when you are upright. Water’s density also offers greater resistance than air, which can further impede visible flow.
Menstrual fluid remains present within the vaginal canal. If you cough, sneeze, or exert abdominal pressure, this internal force can momentarily overcome the external water pressure, potentially leading to a small release of fluid. Once you exit the water, gravity’s influence returns, and your menstrual flow will resume its normal rate.
Swimming Comfortably During Your Period
Swimming during your period is safe and can alleviate menstrual cramps due to endorphin release. To ensure comfort and prevent leakage, several menstrual products are suitable for water activities. Tampons are a popular choice, designed to absorb flow internally, making them effective for swimming. Menstrual cups are another excellent option; these reusable devices collect menstrual fluid internally and create a seal, preventing leaks and not absorbing water.
Period swimwear, featuring absorbent layers, also provides protection and confidence while swimming. It is not recommended to wear traditional pads or panty liners in water, as they quickly saturate and become ineffective. Concerns about hygiene in public pools are largely unfounded; chlorine in well-maintained pools effectively treats bodily fluids, including menstrual blood. Any minimal escape would be highly diluted and unnoticeable.
