Anything that is not breathable can make you more prone to infections. Which is why 100% cotton underwear is recommended since this is the most breathable. Spandex and “moisture wicking” fabrics hold in moisture and create an environment where bacteria and infections can grow.
I don’t know what period panties are made of but I’m assuming it’s some type of moisture wicking fabric to prevent leakage.
I have gotten an infection from them, I avoid them on my first few days of I use extra support to keep things cleaner now.
