I would die quickly because I don’t have any wilderness survival skills and the land I live in (USA) was inhabited by hunter gatherer tribes whose language is completely unrelated to anything I know and whose customs are completely unknown to me as well. But beyond that, even if I got teleported to England where I at least know a similar enough language to where I could figure out middle English decently quickly, I think people seriously overestimate how useful just having modern knowledge is.
For example, say you want to build a gun. Do you know how to forge a gun barrel with medieval steel and make gunpowder out of bat shit and sulfur? Because I sure as hell don’t. I could probably make gunpowder but how the hell would you get the money to pay someone to make a gun barrel for you? And further, even if you had the skills yourself, basically nobody today deals with raw materials as inconsistent as what they were working with back then and therefore don’t have practice working with them. Even if you introduced something like germ theory to them why would anyone believe you? You’d probably get just as sick as everyone else even with following modern sanitation standards for yourself because nobody else would be. Same with math. Want to speedrun introducing calculus to the world? Good luck trying to prove it to medieval mathematicians without having deep knowledge of euclidean constructive proofs and philosophy to even allow for something like an infinitesimal to exist. There’s very little one person can realistically do to change the world on their own.
It probably wouldn’t work though. Say you wash your hands. Okay that helps some against certain diseases but not against respiratory disease, many types of foodborne illness, the plague, etc. You’d still get all of those just as easily as everyone else without also having a backdrop of the germ theory of disease to explain other ways to prevent disease and antibiotics to cure bacterial infections.
This is the state of biology in the middle ages. This is a medieval Scottish bestiary, a book of animals, which contains many interesting facts about animals such as beavers biting their testicles off to throw away pursuers, several animals spontaneously generating from nothing, and many animals that don’t exist (my favorite is the Bonnacon, a bull that spews firey shit as a defense mechanism). Medieval scholars also didn’t accept experimentation as a valid means of gaining knowledge - they were stuck on Plato’s ideas about matter being flawed and untrustworthy and true knowledge only being able to come from Reason (and in the case of the medieval era, Divine revelation). Obviously you could show them bacteria (if you could somehow fashion a powerful enough microscope with medieval tech, which is not a trivial task) and they’d have to believe in it but how would you get them to believe that those little guys cause disease when that took us a couple hundred years in actual history?

I also feel like suggesting people wash their hands, and having it work, would immediately get you accused of being a witch.
