Even in today’s overly sexualized society, vagina is still a “dirty” word. While you might not want to talk about it outright, women need to make sure their good friend “Gina” stays healthy. While some may not think about it, underwear can make or break the health of your vagina.

With it being so close to your lady area at all times, the right pair of underwear is crucial. Starting off, the notion that going “free bird” is healthier for your body is not always true. Going sans underwear during the day can leave you at a higher risk for infection.

Underwear protects the super sensitive female genitalia; tight-fitting clothing rubbing against the body is both uncomfortable and potentially unsanitary. No underwear while sleeping is generally seen as OK. Skipping underwear at bedtime can help the vagina breathe, which helps maintain PH levels and prevent odor.

A large part in choosing the right underwear is fiber content. Many college students don’t think about the fiber content and care of their clothes, let alone their undergarments, but checking the labels of your thongs, cheekies and briefs can help you make sure your vagina is safe and comfortable.

Cotton is king. While there are pros and cons to each fiber content, cotton is the safest bet when it comes to everyday underwear. Cotton is lightweight and breathable since it is a natural cellulosic fiber. It is hypoallergenic, while a nylon or polyester man-made fiber is not.

Nylon is made from petroleum and is often treated with a permanent chemical finish. Neither of these things sound very appealing to be so close to your downstairs.

A time when a man-made fiber such as nylon or polyester can be beneficial is during heavy exercise. Cotton soaks up moisture and can leave your underwear feeling wet and heavy.

Nylon and polyester can help wick moisture away and keep your vagina dry. The downside is man-made fibers can hold in heat, making the nether regions warmer than wanted. A hot crotch region can lead to itching, a rash and discomfort.

While women have been steering away from the thong with the popularization of underwear such as Calvin Klein, thongs are a large portion of some women’s underwear collections. Your friends might have made fun of you in middle school for not wearing a string between your cheeks, but your 13-year-old self might be the one getting the last laugh.

Thongs provide an easy bridge for bacteria to travel from your anus to your vagina. Thongs might provide a panty-line free aesthetic, but they could also provide you with a urinary tract infection. You don’t have to toss out all of your lacey thongs, but wearing them in moderation and avoiding them entirely during exercise can help keep you and your vagina healthy.

The vagina is sometimes neglected in some women’s health care routine, but paying attention to what it has to say is vital. If a pair of underwear leaves you feeling uncomfortable, itchy or with a rash, it is safest to throw it out. Underwear should be replaced every six months to one year.

If your vagina is telling you something, listen. Don’t be afraid to talk with your doctor about any funny business going on, and make sure to get your pap smear at least every three years. Making sure your closest friend is healthy will keep you both happy.
