How Synthetic Underwear May Affect Vaginal pH Balance

Introduction

The choice of underwear fabric affects more than just comfort—it can impact your vaginal health. Synthetic fabrics, such as polyester, nylon, and spandex, are commonly used in mainstream underwear. However, their lack of breathability can disrupt the natural pH and microbiome of the vulva and vagina, potentially increasing the risk of infections.

What Is Vaginal pH?

Vaginal pH typically ranges from 3.8 to 4.5, which is acidic enough to prevent the growth of harmful bacteria. An imbalance can lead to infections.

Impact of Synthetic Fabrics

1. Traps heat and moisture
2. Creates an environment conducive to bacteria and yeast
3. Can lead to itching, odor, and irritation

The Role of Breathable Fabrics

1. Organic cotton is moisture-wicking and breathable
2. Allows the vulva to "breathe," keeping the area dry and at a healthy pH

Gynecologist Recommendations

1. Most OB-GYNs recommend 100% organic cotton for patients prone to infections

Switching to breathable, organic fabrics like those used by Panty Promise may help support a healthy vaginal ecosystem, preventing common pH-related issues.
