You might not think much about vaginal pH, but it plays a key role in your overall vaginal health. Knowing what it is and how it works can help you better understand your body and recognize when something might be off.

What Is Vaginal pH?

pH is a scale that measures how acidic or alkaline something is on a range from 0 to 14. A lower number means something is more acidic, while a higher number means more basic. A healthy vaginal pH typically falls between 3.8 and 4.5, which is considered slightly acidic. This acidic environment helps good bacteria thrive and limits the growth of harmful bacteria or yeast.

When the pH becomes too high (less acidic), it can lead to issues like infections, irritation, or unusual discharge. Staying within a healthy pH range is important for overall comfort and reproductive health.

What Can Affect Vaginal pH?

Several everyday factors can influence your vaginal pH. Some of the most common include the following:

  • Hormonal changes: Shifts during menstruation, pregnancy, or menopause can all affect pH levels.
  • Sex: Semen is more alkaline and can temporarily raise vaginal pH.
  • Antibiotics: These medications kill both good and bad bacteria, potentially disrupting your natural balance.
  • Douching or scented products: Products marketed to “clean” the vagina often do more harm than good.
  • Menstrual products: Some pads or tampons, especially scented ones, may irritate sensitive tissue or alter pH levels.

Not everyone reacts the same way to these triggers, but it helps to be aware of what may cause imbalances.

Can I Tell if My pH is Off?

Yes! Your body can give you signals when your vaginal pH is out of balance. Symptoms like a noticeable or unpleasant vaginal odor; unusual discharge (gray, green, or frothy texture); itching, irritation, or a burning sensation; and more frequent vaginal infections may indicate a pH imbalance.

These symptoms don’t always mean something serious is wrong, but they are worth paying attention to—especially if they happen often or don’t go away on their own.

How to Help Keep Vaginal pH in Balance

Maintaining a healthy vaginal pH doesn’t require special products or a complicated self-care routine. In fact, simple habits are often the most effective.

  • Skip douching and scented soaps: The vagina is self-cleaning. Gentle, unscented soap is fine for the outer area (vulva), but avoid using products internally.
  • Choose breathable underwear: Cotton fabric allows for more airflow and and prevents excess moisture.
  • Change out of wet clothes promptly: Sitting in sweaty gym clothes or a damp swimsuit can create an environment for bacteria to grow.
  • Use protection during sex: Condoms can help reduce pH shifts caused by semen.
  • Consider probiotics: Some foods and supplements can help support healthy bacteria. Ask your provider if this could be helpful for you.
