I. Alternatives to tampons for swimming during your period

Period swimwear, menstrual cups, or free bleeding—here are our three tampon alternatives for swimming. Because yes, it’s now possible to swim without a tampon!

Menstrual swimwear: a practical and discreet solution

The period swimsuit is an innovative solution to swim without a tampon and enjoy the water with total confidence. Designed with technical absorbent fabrics, it holds menstrual flow without swelling. Ideal for teens and women who want to avoid tampons, the period swimsuit offers optimal comfort.

DID YOU KNOW?
Louloucup, your favorite French brand for quality period products, offers you two ranges of absorbent swimsuits for your period. 

Our pretty period swimsuits (one-piece and bikini bottoms), stylish and practical, are perfect for a calm, carefree summer. They’re eligible for our custom bundle and can easily be added to a sliding-scale set with your favorite period underwear.

Four facts you should know about Louloucup menstrual swimwear

Period swimsuits feature layers of high-performance fibers. Able to absorb the equivalent of 2 to 3 tampons (around 10 ml), they’re ideal for light to medium menstrual flow. For heavy flow, we recommend wearing a period cup in addition to your absorbent swimsuit.

Available as bikini bottoms or one-piece swimsuits, the choice is yours! You can wear your period swim bottoms with any bikini top you like, or opt for a one-piece and use it as a bodysuit with shorts or a sarong!

Made with waterproof fabrics, period swimsuits dry quickly and are resistant to chlorine and salt. We still recommend rinsing your period swimwear in clear water after each use.

Period swimsuits offer a high-quality, safe and reliable hygienic solution for the beach or pool. Louloucup period swimsuits are both feminine and high-performing!

The menstrual cup: a discreet and eco-friendly option

Swimming on your period is totally possible with a cup!

The menstrual cup or period cup is an amazing option for swimming. It has won over many swimmers. Inserted into the vagina, this internal, reusable menstrual product made of medical-grade silicone collects menstrual flow without being visible.

More economical than any other menstrual product, the menstrual cup lasts up to 10 years. Unlike disposable tampons, the cup doesn’t break down in water. It’s very popular with active women and athletes, as well as anyone with a heavy flow. It’s a protection that can handle very heavy flows without fear of leaks. With the Loulou cup, you can move, dive, swim and sunbathe with total confidence!

Louloucup’s tips for optimal menstrual cup use

For leak-free swimming, empty your menstrual cup before getting in the water and make sure it’s properly positioned.

If you have a heavy flow, go for the Louloucup medium size model.

After your swim, empty your cup, rinse it, and reinsert it.

Medical grade silicone cups are flexible and easy to insert. No need to worry.

For long days at the beach, you can switch between different clean menstrual cups. This eco-friendly method eliminates waste from tampons.

The free instinctive flow method for certain situations

Last alternative for swimming on your period: FLI or free instinctive flow. This method lets you swim without any menstrual product by holding the blood in using your pelvic floor muscles.

This method is for women who are in tune with their bodies, especially at the end of their cycle when flow is light. While not 100% reliable, this technique offers total freedom.


However, free bleeding carries a risk of leaks and requires impeccable hygiene to avoid infections.


The pressure of the water temporarily slows the flow but doesn’t stop it. In the sea or pool, some women use FLI (free instinctive flow), holding the blood in the vagina. This method is better suited to light flows and requires practice. Although safe, FLI remains an individual solution to test in private before using it in public situations.

II. Swimming on your period: myths, sorting fact from fiction

Myths about menstrual flow in water

Water doesn’t stop your period, but the pressure can temporarily slow the flow. Blood instantly dilutes in water. According to studies, Archimedes’ principle creates upward pressure, which slows bleeding. Even if it seems like you’re not bleeding, the flow continues internally. The average amount lost is 30 to 50 ml per cycle.

Many people think saltwater or chlorinated water completely stops periods, but that’s a myth. Water pressure affects the flow, but doesn’t stop it. According to an IFOP study, 76% of French women worry about leaks while swimming. Tampons can swell in water, making them less practical. For worry-free swimming, choose more suitable and ethical options like menstrual cups or period swimwear.

Swimming during your period and health risks

Swimming during your period poses no health risk as long as you follow basic hygiene precautions. The main health risks come from water quality (germs, pollution), not your menstrual cycle. There are no general medical contraindications to swimming while on your period.


Swimming is possible with endometriosis, but requires proper management of protection. If you have a heavy flow, consider double protection (cup + swimsuit). For athletes, swimming is actually recommended as it can help ease menstrual pain. According to gynecologists, it’s important to change your protection after swimming to avoid infections.

III. How to choose the right protection for your swimming style

Selection criteria based on water activity

Choosing your period protection based on your water activity is important for optimal comfort. For intensive swimming, the menstrual cup is ideal. For occasional swimming, menstrual swimwear may be enough for those with a light to normal flow. For water sports, go for more durable options. Your flow and personal preferences will determine the best choice.

Swimmers tend to choose menstrual cups or period swimwear for the pool.

For water sports, swimsuits with side support are perfect.

At sea, salt-resistant protection is recommended.

The same protections work for lakes.

For a full day at the beach, always bring spare protection for extra comfort. You’ll be glad to have a clean, sand- and salt-free option to change into!

Adjust your protection based on your flow level

For heavy flow, the menstrual cup is the most reliable solution. Our two models, Loulou Rose and Turquoise, are perfect for even the heaviest periods.

Menstrual swimsuits can be paired with a cup for added security.

For light flow, the IUD may be an option.

Once you’re done swimming, whether you’re on the beach or lounging, you can wear period panties (instead of traditional pads).

Our ultimate tip: always keep a spare protection handy for unexpected flow. If your period is heavy, opt for reusable products like period swimwear. For a day at the beach, pack several protections. For variable flow, adjust as needed each day. Signs of change can sometimes appear as discomfort or leaks.

IV. Menstrual protection for swimming: the eco-friendly and budget-friendly approach

Environmental impact of different menstrual products

Alternative period products for swimming help reduce waste from disposables. Menstrual cups and washable swimwear avoid non-recyclable plastics. In France, 45 billion pads and tampons are thrown away each year. Choosing these options protects both your well-being and the planet.


Disposable pads take 400 to 450 years to decompose. On average, a woman uses about 11,000 disposable products in her lifetime. Reusable options, like period swimwear, replace hundreds of disposables and generate less CO2 over the long term. Every action counts—even at the pool.

Long-term cost-effectiveness of reusable period products

Reusable protection costs more upfront, but can save you hundreds of euros over time. A menstrual swimsuit or cup lasts for years. Altogether, each purchase becomes an investment for your wallet and the planet.

Durability and care of reusable protection

After swimming, rinse your swimsuit with clean water to remove salt or chlorine. Wash at 86°F (30°C) with a gentle detergent. Avoid the dryer to protect the technical fabrics. Simple care will extend its lifespan.

Rinse immediately with clean water after swimming.

Wash at a maximum of 30°C (86°F), no fabric softener.

Avoid tumble drying—air dry instead.

Check for wear regularly (seams, stretched fabric).

Chlorine speeds up elastic wear. A well-maintained swimsuit lasts 5 to 10 years. Signs you need a replacement include unexplained leaks or deep scratches. Lifespan also depends on how often you use it and how well you care for it.

V. The health aspect of alternative swimwear protection

Reusable products avoid the chemicals found in disposables. Their organic cotton and natural fibers reduce yeast infections and irritation. In water, they maintain intimate balance, unlike tampons which absorb natural secretions.


Period swimwear uses Oeko-Tex certified cotton and plant-based micro modal. Medical-grade silicone cups don’t release chemical odors or toxic substances. They prevent vaginal dryness, which can cause discomfort. The breathable materials reduce friction in water, which is linked to irritation.

Thousands of women report improved comfort. Competitive swimmers use these solutions for their reliability.


Period swimsuits, cups or free instinctive flow all offer safe ways to swim on your period without a tampon. Dare to try the one that best matches your lifestyle and your needs.

Your summer, your pool, your freedom deserve to be lived to the fullest, with no constraints and no compromises.

FAQ: Is it possible to swim without a tampon?

How do I choose the right size for my period swimwear?

To choose the right size for your period swimsuit, always check the size guide. Measure your waist and hips, as sizing can vary from one brand to another. A well-fitted swimsuit is essential to avoid leaks, especially around the waist and thighs.


Some brands suggest choosing your usual size, while others recommend going up a size if you’re between two. Don’t hesitate to check customer reviews to get a clearer idea.

At Louloucup, the size guide is available on every product page. If you’re unsure, contact us! 🙂

How to manage odors with period products?

Managing odors with period products starts with good hygiene. Odors are often caused by bacterial growth when blood sits for too long.

Change your protection regularly, ideally every 4 to 6 hours, and maintain good intimate hygiene without overdoing vaginal douching.


Wearing period underwear made from absorbent, breathable fabrics (organic cotton) can help control moisture and odors. Natural solutions like baking soda can be used to care for your period underwear. Feel free to check out our special article on managing bad odors.

Can you use lubricant with a menstrual cup?

Yes, you can use a lubricant with a menstrual cup, especially to make insertion easier. Apply a water-based lubricant (this is very important) to the rim of the cup for a smoother, more comfortable insertion.


Some brands offer menstrual cup applicators designed to be used with lubricant. Using a lubricant can be especially helpful if you’re just starting out with a menstrual cup.

Just so you know, Louloucup’s Turquoise model is very soft and flexible. It’s actually designed for beginners, highly sensitive women and teens. Insertion is very gentle and very easy. 

How do you clean your menstrual cup while traveling?

When traveling, rinse your cup with drinking water and a mild, fragrance-free soap. If the water isn’t drinkable, use bottled water or boil it first.


If you don’t have access to water, wipe the menstrual cup with toilet paper or a damp wipe. For deeper disinfection, use a compact menstrual cup sterilizer suitable for travel.

Louloucup offers a cup + sterilizer bundle! Super handy!

Are there period swimsuits for very heavy flow?

It’s still quite hard to find period swimsuits on the market that are suitable for very heavy flow. 

If you have a heavy flow, we recommend going for the period swimsuit + menstrual cup combo. The combination of these two protections is ultra-effective!

Can you take a bath on your period without a tampon?

Yes, of course. It will actually do you good if you have period pain. Warm water soothes cramps and gently massages your belly. Don’t hesitate to treat yourself to this moment of well-being during your period. And obviously without a tampon. It’s unnecessary.

Can you go to the pool on your period?

Yes, of course. Your period should never stop you from doing anything. At the pool, if you want to swim with peace of mind and no fear of leaks, you can go for a period swimsuit, a menstrual cup, a menstrual disc or a sea sponge. A tampon is also an option, but it’s a single-use, disposable and polluting product. It’s better to choose a protection you can reuse!
