Let’s put this one to rest once and for all. You should only use a tampon for up to 8 hours. So, if you’re asking can you sleep with a tampon in, the short answer is yes. Your tampon doesn’t know if it’s day or night and will work the same while you sleep, just be sure to only use a tampon for up to 8 hours. Given that you may sleep for eight hours, when you’re about to hit the sheets and are planning to sleep with a tampon in, first be sure to put in a new one, and then remove the tampon as soon as you wake up. .
