For example, today was fairly chilly out- I went on a long ride, very windy and rainy - but I was quite warm in my cycling tights and jacket. I thought maybe this would help with the temperature thing, because I was still covering up my extremeties. But sure enough- on the drive home- I was freezing cold.
No scientific data here, but I also chill easily after a work out. If you drive to workout (ride, run whatever) be sure to take an extra set of warm clothes so you can get out of your wet stuff as soon as possible.

At home I find that eating, drinking warm fluids (tea) and taking a nice warm shower help too.
