When You Wear A Thong Every Day, This Is What Happens To Your Body

Now that you know thongs are not necessarily the death sentence for a healthy hoo-ha that we thought they were, good old Cosmopolitan has some great tips to make sure you are wearing them in a way that even further reduces risk of discomfort or infection. First, like any other shape of underwear, material matters. Cotton is the safest and smartest material where it comes to your panties, as it's breathable, natural, and the least prone to messing with your pH. Also, it's best if you don't wear thongs in certain situations, like if you have been sick (especially with a gastrointestinal illness) or during a workout. 

In the first case, your immune system is compromised and you are more likely to be passing infection-causing bacteria into your underwear if you have had a tummy illness. With regard to working out, you want to wear something that provides full coverage because the thong can trap sweat more closely to your vaginal area, potentially encouraging the growth of harmful organisms. Further, all the motions could pull the thong back to front over and over again, which, as we learned when we were young, goes against the "wipe front to back" basic rule of hygiene. It's also important to note that, if you already have a vaginal infection, it's best to wait to retire your thong until you are back to normal.
