Can you swim in a pool while wearing period panties?

You have or are about to have one or more pairs of period panties and you’re wondering about using them at the pool? Can you wear period panties in the pool?

Clearly not! Period panties are washable menstrual protection that are not suitable or designed to be fully immersed in a swimming pool or in the sea, for that matter.

Even if it sounds practical, period underwear or washable menstrual panties are absolutely not designed to go in the water. As soon as they’re submerged, their absorbent core becomes saturated and the waterproof layer gives way under pressure, immediately causing leaks and discomfort.

Wearing period panties in the pool is ineffective: the absorbent core instantly fills with water and loses all ability to hold menstrual blood. Result: the protection becomes completely useless as soon as you get into the water.

Period panties are designed for normal use out of the water. Once submerged, the
protection turns into a real sponge, unable to manage your menstrual flow properly. And you’ll get the same result if you try to wear your period panties under a regular swimsuit!

Soaked underwear creates a damp environment that encourages bacterial growth and increases the risk of infection. Chlorine also disrupts the intimate balance and can cause irritation after swimming.

Once your period underwear is saturated with water, it can no longer properly absorb menstrual flow, which means a high risk of leaks coming your way!

Our pretty, absorbent menstrual panties from Louloucup are perfect for all your out-of-water activities: for your workout, your school or work day, and for nighttime. But when it comes to the pool, beach or swimming, it’s better to choose protection that’s truly designed for water.

Whatever your menstrual flow (from very light to very heavy), washable menstrual panties are ideal for all your activities. You can wear them daily without worrying about leaks. They’re a very reliable form of protection.

Good news: there are several effective options that let you enjoy the pool during your period. Just choose the protection that matches your menstrual flow and comfort preferences. Besides the classic, must-have tampon, you now have a wide range of choices to stay protected while you swim.

Right now, a period swimsuit is the most suitable solution for swimming on your period. Unlike simple period underwear worn in the pool, this swimsuit has a double waterproof layer specifically designed to absorb menstrual flow in the water.

- Guaranteed leakproof protection: the outer layer blocks any leaks in the water, while the inner lining absorbs menstrual blood.
- Absorbency tailored to your flow: available for light, medium or heavy flow, it can absorb between 20 ml and 70 ml, the equivalent of 2 to 3 tampons.
- Comfort and quick drying: the technical fabrics are chlorine-resistant, dry quickly after swimming and are much more comfortable than a regular swimsuit.

Good to know! Do you have a heavy or very heavy flow? We recommend combining your period swimsuit with a menstrual cup to avoid any leaks.

The menstrual cup, made from medical-grade silicone, is an ideal internal protection for water activities like swimming. Once inserted, it collects blood without absorbing water and stays leakproof for 4 to 6 hours. You can truly relax!

Its capacity ranges from 15 ml to 30 ml depending on the model, which helps avoid the dryness often caused by tampons. Our Louloucup menstrual cups made in France, free from harmful substances, combine safety and freedom of movement with no leaks.

The menstrual disc sits higher than the cup, near the cervix. Its flat, flexible shape offers optimal comfort, even during long swims.
With a capacity of up to 50 ml, it’s suitable for heavy flows and remains compatible with sexual intercourse. Its lack of a stem makes it particularly discreet and comfortable in the water.

The menstrual sponge, natural or synthetic, is inserted into the vagina to absorb the flow while remaining impermeable to water. Practical and string-free, it perfectly adapts to your shape while you swim.
Remember to rinse it every 3–4 hours for optimal hygiene. Although it takes some getting used to, it offers great freedom of movement in the pool. We recommend pairing it with a menstrual swimsuit if you have a heavy flow.

Free bleeding control involves engaging your pelvic floor to temporarily hold your flow, then releasing it when you go to the toilet. In water, natural pressure slows the flow, making it easier to swim without protection.
This method takes several months of practice and is best suited to light or moderate flows. It’s a popular alternative for those who want to ditch traditional products during water activities.

Discover Louloucup menstrual swimsuits, specially designed to support you during your period, whether you’re at the pool or the beach. These swimsuits perfectly combine comfort, style and technological innovation for worry‑free swimming, whatever your body type. Our team has worked on elegant, very universal cuts while ensuring optimal leak protection.

Our technology is based on a double waterproof membrane: the first ultra-absorbent layer instantly captures menstrual blood and locks it into a breathable fabric, while the second waterproof layer (the outer fabric) blocks any leaks while swimming, even during intense water activities.

• Absorbent layer: a smart blend of natural and synthetic fibres that holds the flow without swelling in water.
  
  
• Waterproof barrier: a specially treated fabric that resists salt or chlorinated water and prevents any leaks.

And as a reminder, OEKO‑TEX certified and PFAS‑free, all our products are kind to your health and the environment.
