Stop BV After Swimming With These Proven Post-Pool Remedies
Okay, so here’s something I never thought I’d have to Google, let alone talk about online—but after my third round of bacterial vaginosis (BV) following a weekend at the pool, I knew I couldn’t be the only one. Turns out, it’s a real thing. Whether you’ve had that annoying fishy odor sneak up on you after a long swim or you’re just tired of BV always coming back after a chlorine dip, you’re not crazy. There’s a legit link. I did my research, tested tips, talked to my doctor, and now I’m sharing what actually worked (and what didn’t) when it comes to how to stop BV after swimming in pool.
Why the Pool Might Be Messing With Your Vaginal Microbiome

You wouldn’t think chlorine would be the bad guy here—it’s supposed to *kill* bacteria, right? That’s the problem. It doesn’t just kill the bad ones; it nukes everything, including your vagina’s good bacteria—specifically the lactobacillus that keeps your pH in check. And when that balance tips, BV loves to take over.
How Chlorine Interferes with Vaginal pH
Swimming pools are full of disinfectants, and that can seriously disrupt your vaginal flora. Chlorine doesn’t play favorites—it wipes out your friendly bacteria, creating the perfect opportunity for anaerobic bacteria (you know, the ones responsible for that signature BV smell) to overgrow.
- Low pH → Chlorine exposure → Higher pH
- Disrupted balance → Less lactobacilli
- Opens door to BV-causing bacteria
Other Pool-Related Triggers
It’s not just the chlorine. Wet swimsuits, lounging around damp all afternoon, and poor hygiene habits post-swim can all add fuel to the fire.
- Wearing a wet swimsuit for hours
- Using scented soaps or bubble bath afterward
- Skipping a quick rinse-off or change
And yes, sex after a pool session without washing up first? Guilty. That, my friends, is a top contributor according to this BV and sexual activity guide.
What Actually Helps: Prevention Tips That Work

1. Change Immediately After Swimming
It seems obvious, but I can’t tell you how many times I used to sit around in a soaked suit for hours. Moisture is BV’s best friend. The minute I started packing an extra dry bikini or clothes and changing right after swimming, my flare-ups dropped dramatically.
2. Rinse Off—Thoroughly
A simple rinse post-pool (just water, no fancy soaps) helps get rid of lingering chlorine. Avoid those floral-scented body washes; they might smell nice but will wreck your vaginal microbiome.
3. Use a Barrier Product
Here’s one that changed the game for me: applying a thin layer of coconut oil before I swim. It acts as a light barrier against chlorine. And no, it doesn’t clog anything or make a mess. Plus, coconut oil has antimicrobial properties. Backed up by what I found in this natural remedy article.
4. Take a Probiotic—Consistently
Don’t wait for BV to strike to pop a probiotic. Daily vaginal health probiotics (with strains like Lactobacillus rhamnosus) are crucial. Honestly, when I started using one regularly, I noticed my “pool reaction time” decreased significantly.
You can dig deeper into how probiotics help from this helpful breakdown.
5. Avoid Sugar Before/After Swim Days
This one’s sneaky. Sugar feeds the bad bacteria. I used to binge on fruity cocktails and poolside treats, but cutting back even a little made a big difference. There’s real science on this, too—check out the piece on sugar’s role in BV.
Don’t Ignore the Signs—Catch BV Early

One thing I learned the hard way? The sooner you catch it, the easier it is to knock out. If you notice a weird smell (especially after sex), grayish discharge, or just feel off down there post-pool day—act fast.
- Change clothes immediately
- Rinse with water (no soap!)
- Apply coconut oil after drying off
- Start or double-down on probiotics
- Cut sugar and stay hydrated
If the signs persist or worsen, don’t hesitate to reach out to a healthcare provider. And no, BV isn’t an STD, but yes—it’s still worth treating. Left unchecked, it can lead to complications. Learn more from this full breakdown on BV symptoms.
What’s Working Long-Term for Me (And Others)

Consistency is everything. When I stick to my routine—probiotic, dry clothes, barrier oil, sugar watch—I stay BV-free no matter how much time I spend in the water. One summer, I swam almost daily and didn’t get BV once. I wish I’d known all this sooner, honestly.
There are also some great longer-term lifestyle tweaks that help prevent recurrence. You can explore more in this solid guide on long-term BV solutions.

How to Treat BV Effectively After It Hits

Sometimes, even with all the prevention in the world, BV still finds a way to crash the party. Been there. If you’re already feeling “off” after your last swim, don’t stress—it’s manageable. But the key is *getting the right treatment* and not half-guessing with Dr. Google (we’ve all done it).
1. Prescription Meds: What Works Fast
When things get stubborn, I don’t wait. I call my doc and ask for either Metronidazole or Clindamycin. These are the go-to antibiotics and usually knock things out within a week—sometimes even faster.
If I’m dealing with a particularly annoying case, or it keeps coming back, I’ve also used boric acid suppositories. It sounds intense, but they help restore the pH balance and kill off lingering bad bacteria.
2. What Not to Do (I Learned This the Hard Way)
- Don’t start douching—ever. It’ll make things worse. Here’s why.
- Skip the essential oils directly inside you. They’re better in a diffuser than your vagina.
- Don’t share towels or swimsuits, especially after a BV bout. Just don’t.

Supportive Remedies That Help Your Body Heal

1. Vaginal Probiotics: Targeted Recovery
After antibiotics, your vaginal microbiome is basically a blank slate. That’s where vaginal probiotics come in. These aren’t just oral supplements—some are designed to be inserted directly. They help recolonize your vagina with good bacteria fast. Here’s a breakdown on how to use them right.
2. Apple Cider Vinegar Baths
This one’s controversial—but I’ve tried short apple cider vinegar soaks (just a half-cup in a shallow bath), and when done sparingly, they help balance pH. But caution: don’t overdo it, and definitely not when irritated or during an active infection.
3. Stay Cool and Dry
Sounds basic, but heat and sweat add up. Especially in the summer when you’re swimming more often. Lightweight cotton undies, no thongs after pool day, and skipping tight jeans for a few days = massive difference. You can get deeper prevention tips from this article on avoiding BV.
Poolside Sex and BV: What to Know

Let’s talk about the thing no one brings up—sex after swimming. Yes, it can mess with your pH too. It’s not about being dirty; it’s about combining chlorine, friction, and body fluids right after your vaginal microbiome just got nuked by pool chemicals. Recipe for a BV flare-up.
Tips for Post-Swim Intimacy
- Shower before and after intimacy
- Use water-based, unscented lubricants
- Have your partner rinse off chlorine too (yes, it matters)
- Give your body a few hours after swimming before having sex
Want to know if you should treat your partner too? This answers that perfectly.
How Your Cycle Might Make You More Vulnerable

Ever noticed BV hits harder right after your period—or just before it? Hormones affect vaginal pH too. Add swimming into that mix, and your body might be more sensitive to BV triggers. When I swam during PMS week or right after my cycle, I almost always had symptoms unless I was extra careful.
More on that in this eye-opener on BV post-menstruation.
Track Your Patterns
Once I started logging swim days, cycle phases, symptoms, and diet, I saw a clear pattern. Knowledge = power. If your symptoms flare up like clockwork, you can prep with probiotics and prevention steps in advance.
Real Talk: You’re Not Alone (and You’re Not “Dirty”)

This part matters. BV isn’t an STD. It’s not your fault. And you’re not gross for getting it after swimming. I know firsthand how frustrating, embarrassing, and repetitive it can feel. But the more we normalize these convos, the faster we can break the stigma and start fixing the root causes.
If you’re swimming regularly, you *have* to understand how your environment affects your vaginal health. Knowledge, support, and consistent habits go a long way. And so does not panicking when symptoms creep up.
