When it comes to underwear, not all panties are created equal, and wearing the wrong type could put your health at risk. Health experts are sounding the alarm about tight, synthetic underwear, especially thongs and shapewear made from nylon, polyester, or spandex. These materials trap heat and moisture, creating a warm, damp environment where bacteria and yeast thrive.
That’s bad news for your intimate health. Wearing synthetic underwear for long periods can increase your risk of urinary tract infections (UTIs), yeast infections, and bacterial vaginosis. And if you’re already prone to irritation or sensitivity, these issues can become chronic.
So, what should women wear instead?
100% cotton underwear—and ideally, light, breathable styles like briefs, boyshorts, or bikinis. Cotton is naturally absorbent and allows air to circulate, keeping your vaginal area dry and less hospitable to harmful microbes. It’s also gentle on sensitive skin, reducing the risk of chafing, inflammation, and allergic reactions.
Even when wearing leggings or fitted clothing, you don’t have to compromise. Many brands now offer seamless cotton panties that stay invisible under clothing while still protecting your health.
Why Organic Cotton Is Even Better
If you want to take it a step further, organic cotton underwear is the gold standard. Unlike conventional cotton, organic cotton is grown without pesticides, harsh chemicals, or bleach—all of which can linger in fabrics and potentially irritate delicate skin. Organic cotton is softer, hypoallergenic, and more suitable for individuals with allergies or chemical sensitivities.
It’s also better for the planet—using less water and supporting eco-friendly farming practices that reduce pollution and promote soil health. When you choose organic cotton, you’re not only protecting your body but also making a sustainable choice for the environment.
