The Truth About pH Balance, Sweat, and Sex in the Heat

Summer is hot. Sexy. Wild. And also… a little chaotic for your vagina.

You’re sweating. You’re swimming. You’re in and out of tight swimsuits, synthetic undies, or sticky festival outfits. You’re probably having more sex (or at least thinking about it). And all of that? It messes with your vaginal pH.

Let’s break it down.

What is pH balance and why does it matter?

Your vagina has a natural pH range of about 3.8-4.5. This slightly acidic environment helps keep your microbiome in check, balancing good and bad bacteria and protecting you from yeast, infections, and irritation.

When your pH gets disrupted, things get funky literally. You might experience:

• Itching or burning
• Unusual discharge
• A “fishy” smell (often bacterial vaginosis)
• Recurring thrush or UTIs

And in the summer? It’s easier than ever to throw things off.

What messes with your pH in summer:

• Chlorinated pools (harsh on delicate skin)
• Tight, sweaty clothing (less airflow = bacteria growth)
• Frequent sex (semen has a higher pH)
• Synthetic lubes or soaps (not vagina-friendly)
• Dehydration (your vaginal tissues need water too!)

How to protect your vaginal health when it’s hot AF:

1. Stay hydrated: Your whole body benefits, including your vaginal tissues.
2. Skip the scented stuff: Wash with water only, and avoid feminine wipes, sprays, or fragranced products.
3. Use a pH-friendly lube: JOMO’s water-based serum is formulated to support not disrupt your natural balance.
4. Air it out: Give your vulva time to breathe. Sleep naked. Switch to breathable cotton underwear.
5. Pee after sex: Always. Every time.

Let’s normalise this:

Caring for your vagina isn’t weird. It’s smart. It’s sensual. It’s part of loving your body in all its messy, magical forms. And when your pH is in check, everything else feels better, especially sex.
