I think most of us would agree that being in the water usually feels like some form of self-care. Whether it’s poolside weekends, ocean dips, hot tub hangs, lake days, or long luxurious baths, water is tied to relaxation, fun, and self-care.
But here’s the truth very few women are ever told:
Water—yes, even “clean” water—can disrupt your natural intimate balance.
Your vaginal pH, your microbiome, your moisture barrier, and even your ability to fend off irritation all shift when exposed to chlorinated pools, hot tubs, lakes, oceans, or bath products. It can be so frustrating to be met with funky symptoms after enjoying the water: itching, irritation, odor, increased discharge, pH swings, or that “something feels off” sensation you can’t quite name.
As a woman who has personally dealt with these issues, and as a health coach who knows many other women who have as well, I can go on and on about why it's so disappointing and frustrating that there has never been a solution to these challenges before now. But, for now, let's just focus on demystifying the topic a bit, since it's so often misunderstood. We're going to look at what really happens when you’re in the water, how different aquatic environments affect you, and why protective practices matter so much for maintaining a healthy vaginal ecosystem.
Your Vaginal Environment: A Delicate, Self-Regulating Ecosystem
The vagina maintains itself through a beautifully complex system that includes:
-
A specific pH range (typically 3.8–4.5)
-
Beneficial bacteria—mainly Lactobacillus—that keep harmful microbes in check
-
A natural moisture barrier
-
Immune cells and microflora that protect against irritation and infection
This ecosystem is highly responsive—and sensitive—to external stressors. Water is one of the biggest.
Even brief exposure to the wrong type of water can:
-
Raise vaginal pH
-
Strip protective flora
-
Introduce irritants or bacteria
-
Disrupt lubrication
-
Trigger inflammation
-
Increase susceptibility to yeast or BV-type symptoms
And different kinds of water cause different kinds of disruptions. Let’s break them down.
1. Chlorinated Swimming Pools: Great for Hygiene, Hard on Vaginal pH
Swimming pools rely on chlorine and other chemical disinfectants to keep water “safe.” While those chemicals protect against pathogens in the pool, they can be irritating to the vaginal ecosystem. Chlorine is designed to break down organic matter—that includes yours.
How Pools Affect Intimate Health:
pH Disruption
Pool water typically has a pH around 7.2–7.8, while your vagina thrives at 3.8–4.5.
Every time pool water enters the intimate zone, it raises your pH, making it harder for beneficial flora to survive.
Microbiome Disturbance
Chlorine can kill off not just bad bacteria—but your good ones too.
Drying & Irritation
Chlorine strips natural moisture, leaving tissue more prone to redness, micro-tears, and discomfort.
Increased Susceptibility
A compromised microbiome means less protection from opportunistic microbes like yeast or BV-causing bacteria.
If you’ve ever felt “off” after a pool day, even when nothing looked wrong externally, this is likely why.
2. Hot Tubs: The Perfect Storm for Intimate Imbalance
Even when they’re properly maintained, hot tubs create a uniquely challenging environment for vaginal health.
Heat + Chemicals + Turbulence = Microbiome Stress
Higher Temperature
Warm water dilates the delicate tissue of the vulva, making it more permeable. This allows chemicals, byproducts, and microbes to enter more easily.
Higher Chlorine & Byproduct Concentrations
Hot tubs often contain more chemical disinfectants to counter constant use and high temps.
Microbe Overgrowth
Hot tubs, even well-treated ones, can harbor bacteria that thrive in warm, agitated water.
What This Means for Your Intimate Balance
-
Increased pH disruption
-
Higher risk of irritation
-
Greater vulnerability to infections
-
More potential for lingering discomfort afterward
If you’ve ever felt extra sensitive after being in a hot tub, that wasn't your imagination—it was your microbiome telling you it needed extra protection.
3. Lakes: Natural, Beautiful…and Full of Microorganisms
Lakes offer a nature-immersive experience, but they also contain:
-
Bacteria
-
Protozoa
-
Algae
-
Sediment
-
Organic debris
-
Runoff contaminants
How Lakes Affect Vaginal Health
High Microbial Load
Even “clean” lakes have abundant microorganisms. Many are harmless—until they enter the vaginal environment, which thrives on a very specific microbial balance.
Sediment and Organic Material
These irritate delicate tissues and can trap bacteria against the vulva and near the vaginal opening.
Runoff and Environmental Toxins
Rain, fertilizers, sunscreen residue, and animal contaminants all end up in lakes.
pH Shifts
Most lake water sits around pH 6–8, again too alkaline for your natural balance.
A single lake swim isn't usually catastrophic, but repeated exposure (or swimming during a time when your balance is already sensitive—think period week, post-intercourse, or after antibiotics) can absolutely throw things off.
4. Ocean Water: Salt, Minerals, and Microbial Diversity
Saltwater is often considered “cleaner,” and in some ways, it is—but not for the vagina.
What Happens When You Swim in the Ocean
Extreme Salt Levels
The ocean is roughly pH 8, and salt can be highly drying to mucous membranes.
This creates:
-
Dryness
-
Post-swim irritation
-
Disruption of healthy bacterial populations
Microbial Diversity
The ocean contains millions of types of microorganisms per drop. Most are harmless—but your vagina doesn't want any foreign microbes, even benign ones.
Sand & Friction
Sand trapped against the vulva can cause micro-abrasions, making tissues more susceptible to irritation or infection.
The ocean may feel healing for your soul—but it isn’t always healing for your microbiome.
5. Baths with Bath Products: Not as "Self-Care" as They Seem
Baths are marketed as self-care, but bubble bath, essential oils, fragrances, and bath bombs can be disruptive—even when they’re labeled “natural" (don't even get me started on that...)
Why Baths Can Affect Vaginal Health
Fragrances & Surfactants
These can irritate both the vulvar skin and the internal vaginal environment if water enters.
Alkaline Water
Most tap water has a pH from 7–8.5, which shifts your natural acidity.
Soaps & Oils
These can coat mucous membranes, clog pores, or disrupt natural flora.
Extended Exposure
Long soaking times increase the likelihood of pH imbalance or irritation.
For women prone to BV, yeast infections, or irritation, bath products often play a bigger role than they realize.
The Hidden Issue: Water Enters More Easily Than You Think
Many women believe the vagina is closed off underwater—but that’s not accurate.
The vaginal entrance isn’t sealed. Water, even a small amount, can move in and out based on:
-
Body position
-
Turbulence in the water
-
Swimming strokes
-
Sitting or squatting underwater
-
Natural tissue flexibility
Especially if you’re using a tampon during your period, the exposed cord wicks water inward, bringing bacteria, chlorine, or other contaminants with it. This is why so many women report irritation or discomfort.
Why Protecting Your Natural Balance in Water Matters
Women often normalize post-swim irritation as “just part of being a woman.”
But your microbiome is foundational to:
-
Healthy pH
-
Comfortable intimacy
-
Odor control
-
Low irritation
-
Immune protection
-
Fewer yeast or BV-type symptoms
Every disruption has a ripple effect. Regular swimmers or women who love hot tubs, ocean dips, or long baths can unknowingly go through a constant cycle:
water exposure → pH disruption → microbiome imbalance → irritation → temporary recovery → disruption again
Breaking this cycle requires prevention—not just aftercare.
Why Women Deserve Better Protection in Water
This is the part that’s rarely talked about: the intimate zone is one of the only areas of the female body that we’re told to simply “hope for the best” when exposed to chemicals, bacteria, and contaminants.
We protect:
-
Our eyes with goggles
-
Our skin with SPF
-
Our hair with leave-in conditioner
-
Our lips with balm
- We wouldn't even dream of letting the water in our mouths...
But for the area with the most sensitive microbial balance, there has been no protective solution—until now.
Enter The V Seal
After years of talking with women who struggled with post-swim irritation, post-bath discomfort, and constant pH swings—paired with my own experiences—I created The V Seal.
From the first-person perspective as its creator:
I wanted something transparent, comfortable, waterproof, hypoallergenic, and easy to apply—something that would keep chemicals, bacteria, and contaminants out while women enjoy their time in the water.
