Time to read 8 min
Introduction
The first sign is often subtle: discharge that looks a little thinner than usual, a scent that’s stronger after sex, or a feeling that your vaginal pH has shifted. If you’re noticing patterns like that, you’re not alone, and it doesn’t mean you’ve done anything “wrong”.
If you want a quick baseline before we go deeper, read our guide on vaginal discharge, the vaginal microbiome, and vaginal pH here: https://ellasie.com/blogs/womens-wellness-guides/vaginal-discharge-microbiome-ph
This medically reviewed guide explains why winter routines can nudge vaginal pH off balance, what drives BV recurrence, how to tell BV vs thrush vs UTI, and what actually helps in a calm, realistic way.
Key takeaways:
BV is a vaginal microbiome imbalance, not poor hygiene. Over-washing can make vaginal pH more unstable.
• Winter doesn’t “cause” BV, but winter habits can stack triggers that increase BV recurrence risk for some people.
• BV recurrence is common, and it’s usually about triggers plus consistency, not willpower.
• If symptoms are new, severe, persistent, or recurring, get checked. BV can overlap with thrush, UTIs, and other conditions.
Definition:
Bacterial vaginosis (BV) is a shift in the vaginal microbiome where protective lactobacilli decrease and other bacteria increase, often linked with thin grey-white discharge and a fishy odour, especially after sex. Vaginal pH is often higher than usual during BV, which can contribute to symptoms and BV recurrence patterns.

BV, vaginal pH, and the vaginal microbiome: what’s happening
BV is one of the most common causes of unusual vaginal discharge. BV is not typically “a cleanliness issue”, and over-cleansing can disrupt the vaginal microbiome and affect vaginal pH.
A few grounding points that matter for BV recurrence:
• BV often comes and goes in cycles, which is why recurrence can feel frustrating.
• Vaginal pH is part of the environment that supports a stable vaginal microbiome.
• Some people have mild symptoms, which makes patterns harder to spot until a flare happens.

It helps you separate urinary patterns from vaginal pH patterns so you’re not guessing.
Does winter affect vaginal pH and BV recurrence?
Winter itself isn’t a magic BV switch, but winter changes routines, and routines change the vaginal environment. That’s the real link: winter habits can make vaginal pH more likely to drift and can make BV recurrence more likely for some people.

“Winter was when my vaginal pH felt most unpredictable. Tight layers, stress, and baths made it worse. Keeping it simple and consistent helped me spot my triggers.”
Baths, scented products, and over-cleansing
Winter is when bubble baths come back, “freshness” products get marketed harder, and people wash more aggressively because they feel “off”. But when you’re dealing with vaginal pH instability or BV recurrence, over-cleansing can backfire.
Avoid:
• Bubble baths, bath oils, perfumed soaps
• Vaginal deodorants, washes, douching
• Antiseptics in the bath
Instead:
• Gentle external-only washing with water and a mild, unscented cleanser if needed
Some Options from Ellasie
Stress, sleep, and vaginal microbiome stability
Winter is often darker, busier, and more stressful. Stress can influence immune responses and microbiome stability, and that can show up as vaginal pH shifts for some people.
If stress feels like part of your story, read this deep dive on cortisol and the vaginal microbiome here: https://ellasie.com/blogs/womens-wellness-guides/stress-vaginal-odor-cortisol-connection
Layers, sweat, friction, and airflow
Thermal tights, gym leggings, shapewear, and long days in multiple layers can trap heat and moisture. That doesn’t “create BV overnight”, but it can contribute to irritation and instability for people prone to BV recurrence, especially if vaginal pH is already sensitive.
Simple wins:
• Change out of sweaty clothes sooner
• Choose breathable underwear
• Keep laundry products simple for underwear
BV vs thrush vs UTI: how to tell
Direct answer: BV is more likely with a fishy odour and watery or thin grey-white discharge. Thrush is more likely with itching and thick, clumpy discharge. A UTI is more likely with burning during urination plus urgency and frequency.
Quick pattern guide:
Discharge
• BV: thin, watery, grey-white
• Thrush: thick, white, clumpy
• UTI: usually minimal discharge
Smell
• BV: fishy, often worse after sex
• Thrush: mild yeasty smell or none
• UTI: usually none
Itching
• BV: uncommon
• Thrush: common, often intense
• UTI: not typical
Urinary symptoms
• BV: not typical
• Thrush: not typical
• UTI: common
If you’re stuck between “vaginal pH issue” and “urinary issue”, don’t self-label for too long. Patterns matter, and testing is often the fastest way to stop the cycle.
A routine friendly option from Ellasie
What may help: a winter-proof vaginal pH routine
Direct answer: the safest winter strategy is gentle external cleansing, avoiding irritants, improving breathability, and getting checked quickly if symptoms persist or if BV recurrence is frequent. You can also try this gentle option from Ellasie.
“I used to think BV meant I wasn’t being clean enough, so I washed more. Once I simplified my routine and stopped using scented products, everything felt more manageable.”
Why BV recurrence happens (and why routines can feel “ineffective”)
Common reasons BV recurrence happens or improvements don’t “stick”:
• Not giving changes enough time. BV recurrence is often cyclical.
• Inconsistent routines. A few days on and off doesn’t stabilise vaginal pH.
• Hidden irritants. New detergents, scented washes, bath products, “freshness” sprays.
• Treating the wrong thing. Thrush and UTIs can mimic BV-like discomfort, and vaginal pH can shift for reasons that aren’t BV.
• Not identifying a trigger pattern. Sex, stress, and product changes often show up repeatedly.

A practical 7 day reset
External-only gentle wash, no perfumed products
Cotton underwear, simple detergent for underwear, change out of sweaty clothes quickly
That’s it. BV recurrence often improves when you remove the most common disruptors that raise vaginal pH instability.
Sex, semen, and vaginal pH
Some people notice BV recurrence patterns linked to sex. Semen can temporarily change vaginal pH, which may matter for people who are already sensitive. If BV recurrence clusters after sex, that’s worth discussing with a clinician and may be worth experimenting with barrier methods to see if it changes the pattern.
Where pre and probiotics fit
You’ll see probiotics everywhere, but the honest position is: evidence is mixed and guidelines stay cautious. Probiotics are not a replacement for diagnosis or treatment. They can be part of a routine for some people who want to support a stable vaginal microbiome and vaginal pH, but expectations should be realistic.

When to speak to a clinician
Speak to a clinician if symptoms are new, severe, persistent, recurring, or you’re pregnant. Also seek advice if you have pelvic pain, fever, unusual bleeding, or symptoms that return after treatment. Recurrent symptoms need proper assessment to confirm whether it’s BV, thrush, UTI, or something else.

Frequently Asked Questions
What is vaginal pH and why does it matter for BV recurrence?
Vaginal pH is part of the environment that supports a stable vaginal microbiome. When vaginal pH becomes less stable, it can be easier for imbalance patterns to show up again, which may contribute to BV recurrence in some people.
Can winter routines affect vaginal pH and trigger BV recurrence?
Yes. Winter habits like bubble baths, scented products, tighter layers, and staying in damp clothes longer can irritate the area and make vaginal pH feel more unpredictable. For people prone to BV recurrence, those routine shifts can matter.
Can vaginal odour be related to vaginal pH changes?
Sometimes. Vaginal odour can change when the vaginal environment changes, including shifts in vaginal pH and microbiome balance. Because odour can overlap with BV, thrush, or other causes, it’s worth getting checked if it’s new, strong, persistent, or recurring.
What vaginal pH symptoms are most common with BV compared with thrush?
With BV, people often notice a stronger vaginal odour and thinner watery or grey-white discharge. Thrush is more likely to cause itching and thicker, clumpy white discharge. If you’re unsure, testing helps because symptoms can overlap.
If I have vaginal odour after sex, does that automatically mean BV recurrence?
Not automatically. Semen can temporarily change vaginal pH, and some people notice odour changes after sex without it being BV. But if vaginal odour after sex keeps repeating, especially with discharge changes, it’s sensible to speak to a clinician to rule out BV recurrence and other causes.
Can I “reset” vaginal pH quickly to stop BV recurrence?
There isn’t a safe instant reset. The most reliable approach is removing common disruptors and keeping a steady routine: gentle external-only washing, avoiding fragranced products, breathable underwear, and getting assessed if symptoms persist or BV recurrence is frequent.
Do intimate washes help vaginal pH or vaginal odour?
Usually not. Many intimate washes and fragranced products can irritate the area and make vaginal pH less stable, which may worsen vaginal odour or contribute to BV recurrence patterns for some people. External gentle washing is enough.
Can probiotics improve vaginal pH and reduce BV recurrence?
Probiotics are not a replacement for diagnosis or treatment, and evidence is mixed. Some people use probiotics as routine support for the vaginal microbiome and vaginal pH, but expectations should be realistic. If BV recurrence is frequent, clinician guidance is the priority.
