Swimming is one of the most freeing, joyful ways to move your body — and your period shouldn’t stop you from getting in the water. Whether you’re heading to the beach, the pool or a tropical holiday, there are safe, comfortable ways to swim while menstruating.
In this guide, we’ll cover everything you need to know about swimming on your period - from busting myths, to comparing product options, to answering your most common questions.
Can You Swim on Your Period?
Yes — absolutely! There’s no medical reason why you can’t swim during your period. Being in water doesn’t stop your flow completely, but the water pressure can reduce it slightly. With the right protection, you’ll stay comfortable, leak-free, and confident.
In fact, swimming may even help ease cramps thanks to gentle movement and muscle relaxation.
For stress-free swimming, you’ll need an internal product like a menstrual cup, disc, tampon or sponge.

Tips for Swimming Leak-Free
- For all products - insert a fresh product before swimming — for maximum wear time and peace of mind.
- For cups - check the seal: squat, bear down, or run a finger around the rim to make sure it’s properly in place to avoid leaks.
- For discs - ensure it's inserted correctly - you cup is held in place by the pubic bone - ensure the front of your cup is tucked up above the pubic bone
- For tampons - pack a spare tampon: Ensure your tampon string is tucked in and take wipes, a small wet bag with a spare tampon if you’ll be out for hours.
- For sponges - ensure it's positioned correctly: wet the sponge, insert fully, and check it’s snug but comfortable.
- Choose swimwear wisely: darker colours, patterned fabric or high-waist bottoms offer extra confidence.
- Change after swimming: if possible, shower after swimming and clean and replace your product to avoid irritation.
Swimming on Heavy Flow Days
Cups, discs, sponges and tampons all handle heavy flow well:
- Cups & discs: High capacity (often 3–4× more than a tampon), making them ideal for swimming.
- Sponges: Absorb well and mould to your body shape for leak protection.
- Tampons: use a Super, Plus or Ultra tampon
If you’re prone to leaks, wear period swimwear bottoms for backup and empty your cup or disc just before swimming.
Swim with Confidence
Many people feel anxious about leaks or embarrassment, but remember no one can see your cup, disc or tampon and the water itself makes leaks less likely.
Wearing swimwear that makes you feel good and preparing ahead can make all the difference.
FAQs About Swimming on Your Period
Will chlorine or salt water affect my cup or disc?
No — silicone and TPE products are safe in pools and oceans. Just rinse with fresh water afterwards.
Can I swim with a menstrual sponge?
Yes, but check it’s placed securely. Some sponges are reusable, while others are single-use — make sure you know which type you’re using.
What if I leak in the water?
Leaks are very rare with cups and discs, but if they happen, the water dilutes blood quickly. Dark swimwear adds extra peace of mind.
How long can I wear my menstrual cup or disc while swimming?
Up to 12 hours however, we recommend changing if you’ve been swimming for several hours.
I’m a teen. What’s best for me?
You can start with a small cup or disc or tampon if that feels easier. Practice wearing your cup or disc before swimming (know as doing a 'dry run') so you know how it feels.
