You’ve been grabbing a foreign object and shoving it inside of you since you were a preteen. I’m talking about tampons, of course. But how much do you really know about the synthetic fabrics that sit in your body, sometimes for hours at a time? Here are 15 facts about tampons that you should know.

 Your tampon is bleached with chlorine

Chlorine, as in the stuff used to keep hot tubs and swimming pools clean? Yes. Cotton and rayon tampons aren’t naturally that white. Chlorine can upset your hormonal balance and cause health problems, which is one of the reasons why you shouldn’t leave tampons in very long.

They can dry you up

The surfactants in tampons used to absorb the blood will also absorb regular, healthy vaginal secretions, which is why your vagina can be very dry after using one. Without those secretions, your vagina can’t fight infection as well.

Your flow affects how many you use

When your flow is very heavy, you need to change your tampon every two to three to hours because the fibers are essentially all filled up with blood. On lighter days, you can get away with changing your tampon every three to six hours.

Your tampon doesn’t go where you pee

In case this hasn’t been cleared up for you yet (and this actually hasn’t been cleared up for a lot of women!) you have three holes down there: the urinary, the vaginal and the anal. Your tampon doesn’t go in your urethra because you would obviously urinate all over it when it’s time to go to the bathroom.
