Does staying out in the cold too long have any problematic health factors?

Well, today I’ve been out walking around all day long. It was snowy and cold out. My fingers turned all pink and my legs felt all numb, and my cheeks felt all stiff and red. (I forgot to bring good winter attire). Will that do me any bad now or in the future?

I worry that my skin may be ‘hurt’, from being out in the cold for too long. Will my hands be okay, from having no feeling to them, and being all pink? What about my legs? They were numb and my knees and hips kind of hurt for unknown reasons.

Does being out in the cold for a couple of hours at a time have any bad factors that I should worry about? If so, I’ll try to avoid walking out in the cold. It was only -9 out, but it was really cold after being in for a long time, also the wind chill contributed to the cold. (I’m not sure what the wind chill was)
