We’ve heard the question “Can you swim on your period?” many times before. Short answer: Yes, and we’re happy to explain how. Your period doesn’t need to ruin your summer fun! You can go swimming during your period with the right protection, like period swimwear, natural tampons, or cups.
Swimming can be a great way to relax and boost your mood during your cycle. To avoid worries about leaks, comfort, or hygiene, there are several helpful options. In this blog, we dive deeper into the period swimsuit—or bikini: how does it work, and is it for you? Here's your answer to whether you can swim on your period—
How to Swim During Your Period?
In general, yes—you can swim during your period. It’s important to listen to your body and energy levels, though. Physical activity can help relieve cramps, and swimming is especially effective. Plus, the temperature of the water can have a soothing effect. On hot days, remember to hydrate well and drink plenty of water.
Also, choose a menstrual product that fits your activity level. Whether you're lying on the beach or doing laps in the pool, choose something that makes you feel good. Curious about your options? Check out our blog on how to swim during your period
How Well Does Period Swimwear Work?
A period swimsuit or bikini is designed to keep you comfortable and protected—even while swimming on your period. This type of swimwear has special layers to prevent leaks. The Cheeky period swimsuit has 4 unique layers, each with its own function:
First Layer: This layer is in direct contact with your skin. It’s made from a soft, moisture-wicking fabric to keep you feeling dry and comfy.
Second Layer: This is the absorbent layer, which captures menstrual fluid. It can absorb the equivalent of two tampons.
Third Layer: This is the waterproof layer that prevents any blood from leaking through the swimsuit—giving you extra confidence in the water.
Fourth Layer: The outermost layer, made from elastic, durable fabric similar to regular swimwear. It looks stylish and fits your body perfectly.
The swimsuit received a 5/5 star review from Riet (translated):
"This wasn’t our first choice—we had ordered something elsewhere first, but it was such a disappointment. Then we ordered here, where we also got the period briefs. My daughter (14) is super happy, it looks amazing on her, she feels good in it, and there’s room to grow without it being baggy."
Does It Look Different Than a Normal Swimsuit?
Nope! It looks just like regular swimwear. The outer layer is made from material that mimics traditional swimwear, with the same fit and style. You won’t be able to see the absorbent lining.
Most brands choose darker colors for period swimwear to make you feel even more secure. Period swimwear is subtle and practical—so you can feel just as confident as you do in any other swimsuit!
Can You Swim on Your Period with a Heavy Flow?
Yes, you can swim even with a heavy flow. You might wonder whether a period swimsuit offers enough protection—it can absorb up to two regular tampons’ worth.
However, for heavier flows, we recommend combining your swimsuit with extra protection, like a tampon or menstrual cup. This way, you can enjoy the water worry-free.
Tip: The Merula cup is available in a larger size—so you can confidently answer can you swim on your period with a big "yes," even during a heavy flow.
Can You Swim with Period Underwear?
No—period underwear is not designed for swimming. You can swim on your period, but go for something like a period swimsuit.
There are a few key reasons why period underwear isn’t the same as period swimwear:
Swimwear has a waterproof layer to prevent pool water from soaking into the absorbent lining. Period underwear doesn’t, so it soaks up water and can no longer absorb menstrual fluid.
Period underwear also can’t prevent blood from leaking into the water—something period swimwear does do.
Lastly, period underwear looks different than swimwear because of the material. If you don’t mind that, it’s great for lounging by the pool—but in the water, choose period swimwear.
Looking for another option? Consider natural tampons or Merula cups.
