As the weather heats up, it's only natural that you sweat more. You're hanging in bikinis, indulging tropical drinks, and meeting strangers who you may find yourself in bed with. These things are some of summer's delights. But all of the above can leave a mark on a gal's vagina. So, if you find yourself wondering, why does my vagina itch, you may find that summer lifestyle habits are likely culprits.

There are some really common reasons vaginas get itchy. As Everyday Health pointed out, the vagina is an internal organ that comes in contact with a lot of external things. To mitigate that "contact," vaginal pH acts as a barrier, containing lots of helpful juices, including beneficial bacteria, necessary to keep your vagina clean and healthy. Have you ever heard that kinda creepy metaphor that the vagina is a self-cleaning oven? Well, vaginal pH explains the science behind that one. Still, sometimes your body doesn't know how to relieve that itch.

Before you scratch — don't scratch an itchy vagina and end up irritating it more — figure out if any of the following might be causing your discomfort. If so, talk these things over with your gynecologist for a detailed diagnosis and plan of action.

1. Your Underwear


According to Huffington Post, your underwear can make your vagina itch. The article recommended staying away from silk, shape wear, and underwear that is too tight because these trap moisture around your vagina, and you don't want to sit in that all day. Additionally, thongs might transfer fecal matter from your anus to your vagina, causing an infection that needs physician's care. So, play it safe and stick with breathable cotton knickers if you're feeling the burn.

2. You're Not Washing Properly


There's a proper way to wash your vagina, ladies. Women's Health advised you use an unscented bar soap to gently wash your vagina once a day. Over-washing can cause tears in the vagina, which leads to infection. Additionally, body washes with tons of fragrance throw of vaginal pH, and can make your vagina itchy as hell.

6. You're About To Get Your Period
