The choice of underwear may seem like a minor detail at first glance, but the type of material, cut, and wearing habits are directly related to intimate hygiene and infection prevention.
Comparison of materials
Cotton. The most recommended material by gynecologists and urologists — it naturally "breathes", absorbs moisture and does not create an airtight environment. Pure cotton underwear reduces the risk of fungal infections (candidiasis), which most often develop in a favorable, moist and warm environment.
Synthetic fibers (nylon, polyester). Less breathable, traps moisture close to the skin, which increases the risk of bacteria and fungus growth. Most sports or "aesthetic" underwear is made from these materials — their use is not prohibited, but prolonged, daily wear is not optimal from a hygienic point of view.
Silk. A natural material, it breathes even better than cotton in some respects, but it is expensive and requires gentle care — making it less popular for practical, everyday use.
The meaning of the wound
Tight, body-hugging underwear (especially thongs) increases friction and the risk of mechanical transfer of bacteria from the anus to the vagina — it is especially important to maintain good hygiene habits (wiping from front to back) for wearers of this type of underwear. Loose, loose-fitting underwear reduces this risk, although the ultimate choice is a matter of personal comfort and style.
The issue of night driving
Some gynecologists recommend sleeping without underwear at night or even wearing looser underwear than usual — this reduces moisture buildup over a long period of time and gives the skin a chance to "rest." This is not a mandatory recommendation, but an additional measure for those who often experience irritation or fungal infections.
The issue of post-workout underwear
Wearing sweaty sports underwear for a long time after exercise is one of the most common, yet rarely discussed, risk factors for fungal infections and irritation — it is recommended to change underwear as soon as possible after exercise, along with showering.
The impact of detergents
Detergents containing strong fragrances or preservatives (chemicals with anti-fouling properties) can remain in the fabric in sufficient quantities to cause contact dermatitis on sensitive skin. If you frequently experience unexplained irritation, it may be worth trying a hypoallergenic, fragrance-free detergent, especially for intimate apparel.
Summary
The choice of underwear is not a separate, isolated factor, but one element in the overall system of intimate hygiene — regular wearing of cotton, loose underwear, clean washing, and timely changes together significantly reduce the risk of infections and irritation, even without special or expensive products.
