Underwear and Intimate Health: Myths and Realities

With all the advice we hear here and there, it's not always easy to know what's true. Do thongs cause infections? Is cotton really essential? Are tight clothes dangerous for intimate health?

This article disentangles myths from research-based recommendations to help you make informed choices without sacrificing style or comfort.

The Most Common Myths

Myth 1: Thongs cause vaginal infections

This is one of the most persistent misconceptions. However, a study published in Obstetrics & Gynecology Research did not show a significant increase in infections linked to wearing thongs. The Cleveland Clinic also confirms that no clear correlation has been established between wearing thongs and the risk of vaginal infection.

What matters more is the cleanliness of the underwear, the presence of a cotton gusset, and avoiding prolonged wear in humid conditions.

Myth 2: Tight clothing causes urinary tract infections

The idea that tight leggings or snug underwear promote UTIs is widespread, but research has not established a direct link. It's not the cut that's the problem, but accumulated moisture. Changing underwear after exercise is enough to limit this risk.

Myth 3: Antibacterial fabrics are better for intimate health

Some underwear is marketed as "antimicrobial." These properties often come from chemical agents whose long-term effects on intimate flora remain uncertain. Regular washing and choosing a natural material in direct contact with the skin remain much more effective.

What Science Actually Recommends

The cotton gusset: essential, not optional

Most healthcare professionals recommend that the crotch area be made of cotton, regardless of the underwear's main material. Cotton is naturally breathable and absorbent: it allows air to circulate, wicks away moisture, and helps maintain the natural balance of vaginal flora.

Infections like candidiasis and bacterial vaginosis thrive in warm, humid environments. A cotton gusset creates the opposite conditions: dry and airy.

That's why every LICA Wear seamless panty includes an elongated 100% cotton gusset, even if the rest of the fabric is nylon and elastane. The comfort of technical fabric, with the health benefits of cotton where it matters.

Comfort reduces irritation

Poorly fitting underwear or rubbing seams can cause repeated micro-irritations in the genital area. These irritations, though mild, can disrupt the skin's natural protective barrier and promote infections.

Seamless panties eliminate this problem: their smooth surface has no friction points, and their elastic fabric adapts to the body without compressing. To learn all about how to choose invisible and comfortable underwear, check out our complete guide to invisible underwear.

The right size, not too tight, not too loose

Underwear that's too tight traps moisture and causes friction. Too loose, it slides and bunches up. The right fit is one that stays in place naturally, effortlessly. To choose the right size for seamless panties, our practical size guide provides all the benchmarks.

Good daily practices

Changing underwear every day, and immediately after physical exercise, remains the most effective measure for maintaining good intimate hygiene. Moisture accumulated after exertion is the main risk factor for irritation and infection.

For washing: a mild, fragrance-free detergent, cold water, and air drying preserve both the fibers and the skin. Avoid fabric softeners, which can irritate the intimate area and degrade elastic fibers.

Varying styles throughout the week, between thongs, Brazilian cut, and bikini briefs, also allows the skin to breathe differently depending on the cut.
