It happens. You’ve had the weekend at the lake or the beach house booked for months, and then you feel it. That unmistakable, frustrating itch. The burning. The sudden realization that a yeast infection has decided to crash your vacation. Now you’re staring at your swimsuit and wondering: can you go swimming with a yeast infection, or is that just asking for a week of misery?
Honestly, the short answer is yes. You can physically get in the water. No, you aren't going to "infect" the entire public pool or leave a trail of fungi in the ocean like some kind of biological hazard. Yeast infections aren't contagious in that way. But just because you can do something doesn't always mean it's a great idea for your body’s recovery.
Swimming involves a tricky trifecta of irritants: chemicals, moisture, and friction. If you handle those three things poorly, a minor itch can turn into a full-blown internal firestorm.
The Chlorine Problem: Friend or Foe?
Chlorine is designed to kill bacteria. That sounds like a good thing, right? Well, not exactly for your vaginal microbiome. Your vagina is a delicate ecosystem balanced by "good" bacteria, primarily Lactobacillus. These little guys keep the pH acidic, which prevents Candida albicans (the yeast) from overgrowing.
When you jump into a chlorinated pool, that chemical doesn't just stay on your skin. It gets everywhere.
Chlorine is indiscriminate. It kills the bad stuff, but it also wipes out the Lactobacillus that you desperately need to fight off the yeast. If you’re already mid-infection, the pool water can strip away your remaining natural defenses. It’s like trying to put out a fire by removing the fire department.
Then there's the pH issue. According to the CDC, most pools aim for a pH between 7.2 and 7.8. Your vagina, however, wants to stay much more acidic, usually between 3.8 and 4.5. Introducing alkaline pool water can throw your chemistry into a tailspin, potentially making the infection last longer or feel more intense.

Saltwater and Lakes: Are They Any Better?
If you're at the beach, you might be in better luck, but it isn't a free pass. Saltwater is generally less irritating than harsh pool chemicals. Some people even swear by it for various skin issues. However, the ocean isn't sterile. You’re dealing with sand (hello, friction) and microscopic organisms that can cause secondary irritation.
Lakes and ponds are a different story.
Stagnant water often contains bacteria that can lead to other issues, like bacterial vaginosis (BV). If your vaginal flora is already compromised by a yeast infection, you’re more vulnerable to "hitchhiker" infections. It's a risk. Not a huge one, but it's there.
The Real Enemy: The Wet Swimsuit
The water itself isn't usually the biggest culprit. It’s what happens after you get out.
Yeast loves three things: warmth, darkness, and moisture. A wet spandex swimsuit provides all three in a perfect, high-performance package. Spandex is notoriously non-breathable. When you sit around in a damp bikini bottom for three hours while eating fish tacos on the boardwalk, you are essentially creating a greenhouse for fungus.
It’s gross to think about, but it’s true.

If you decide that swimming with a yeast infection is happening regardless of the risks, you have to be militant about your wardrobe. The second you are done swimming, that suit needs to come off. Not in twenty minutes. Not after one more drink. Now.
Managing the Itch While You’re Out
If you're currently using a topical cream like Monistat (miconazole), swimming is going to be a mess. These creams are often oil-based. Water washes them away, rendering the treatment useless. Even worse, the combination of the cream and the water can create a sticky, goopy residue that traps bacteria against your skin.
If you are on an oral medication like Fluconazole (Diflucan), you don't have to worry about the medicine washing off. But you still have to deal with the physical sensation of the water hitting irritated tissue.
For some women, the cool water of a pool feels like a godsend. It numbs the burning. For others, the movement of the water and the chemicals make it feel like they’re sitting in a bowl of salsa. You have to listen to your body. If it stings the moment you wade in, turn around.
Why You Might Want to Skip the Hot Tub
If there is one place you should absolutely avoid, it’s the hot tub.
Hot tubs are basically giant petri dishes of warmth and chemicals. The high temperatures actually encourage yeast to bloom faster. Plus, the high concentration of chemicals used to keep hot tubs "clean" is much harder on your sensitive skin than a standard swimming pool. Just don't do it. Your future self will thank you.

How to Swim Safely (If You Must)
If you've weighed the pros and cons and decided the water is calling your name, follow these "damage control" steps to make sure you don't end up in more pain tomorrow.
- Apply a Barrier: Some gynecologists suggest a very thin layer of plain petroleum jelly or a coconut oil-based barrier balm on the external area (the vulva) before getting in. This can act as a shield against the chlorine. Don't go overboard; you just want a light film.
- The 60-Second Rule: As soon as you exit the water, head straight for the shower. Rinse off the chlorine or salt with fresh, clean water. Do not use scented soaps. Just water.
- Pat, Don't Rub: When drying off, use a clean, soft towel and pat the area dry. Friction is your enemy right now. If you have a hairdryer, using it on the "cool" or "low" setting to ensure you are 100% dry before putting on clothes is a pro move.
- Cotton is King: Put on loose-fitting cotton underwear. Skip the tight denim shorts for the rest of the day. Give your body some literal breathing room.
- Tampon vs. Cup: If you’re also on your period, a menstrual cup is generally better than a tampon when you have a yeast infection. Tampons can absorb the chlorinated water and hold it right against the vaginal wall. A cup creates a seal, keeping the pool water out.
When to Stay on the Pool Chair
Sometimes, the best move is to just be the person who holds the towels.
If your skin is broken or raw from scratching, stay out of the water. Period. Open sores and pool chemicals are a recipe for a secondary skin infection or even cellulitis in extreme cases. It’s not worth the risk.
Also, if your symptoms include heavy discharge or a strong odor, you might not just be dealing with yeast. It could be BV or an STI like Trichomoniasis. These often require different treatments, and swimming can mask the symptoms or make the inflammation worse before you’ve had a chance to get a proper diagnosis.
Actionable Next Steps for Recovery
If you’ve already gone for a dip and you’re feeling the burn, or if you’re trying to clear this up before the next pool party, here is what you need to do:
- Ditch the DIY: Don't try to "wash out" the pool water with a douche. Douching is never a good idea, but it's especially harmful when you're already dealing with an infection. It pushes the yeast and chemicals further up into the cervix.
- Probiotic Punch: Start taking a high-quality probiotic specifically formulated for vaginal health (look for Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14). You can also eat unsweetened Greek yogurt, but don't put it... you know... where it doesn't belong. Keep it in the bowl.
- Hydrate: It sounds basic, but drinking a ton of water helps flush your system and can slightly alter the acidity of your urine, which makes things more comfortable when you have to go.
- See a Professional: If this is your first yeast infection, or if it hasn't cleared up after three days of over-the-counter treatment, go to an urgent care or your OB-GYN. You might need a prescription-strength antifungal.
- Sleep Commando: Give yourself the night off from underwear. Sleeping in loose pajama pants or nothing at all allows the area to stay dry and cool, which is the fastest way to kill off a yeast overgrowth.
Swimming with a yeast infection is mostly a matter of personal comfort and diligent aftercare. If you can't resist the pool, just be prepared to spend the rest of the day being very, very kind to your body. Rinse, dry, and breathe. That's the mantra.
