Experts believe that your underwear preferences could be affecting your health.

Octavia Cannon, a board-certified OBGYN, told Seventeen why women might be putting their health at risk with their underwear choices.

Instead of giving women a long lecture, however, Cannon kept it brief by outlining these six simple rules for picking out underwear.

1. Avoid thongs
Even though saucy lingerie can help turn up the heat in the bedroom, wearing a thong could be detrimental to your health.

Cannon explained the stringed undies can cause bacteria, including E. Coli, to spread from the anus to the vagina.

She revealed: “Think about where the string slides when you sit down in a thong.”

If you’re not willing to part with the skimpy panties anytime soon, take them off at night to give your body a breather.

2. Pink cotton undies
Cotton is a more breathable material than silk or other lacy undies.

Cannon believes that choosing the airy option can stop grossness festering in your underwear and prevent infection.

3. Always change your underwear after exercising
The post-gym shower won’t do much for your hygiene unless you bring along a fresh pair of panties.

Cannon revealed that your sweaty fitness gear is often a place that harbors infection.

She explained: “Yeast and bacteria love a warm, moist, dark environment.”
