Question About Walking And Sweating

One of the most annoying things about walking from the train station to school (.76 miles) is that during the winter or summer, when I reach the school, I'm hot and sweaty. Winters are the worst, because you're extremely cold, yet sweaty.

Question is, if I start walking let say 5 miles plus a day, would it eliminate the sweat when I get to school after the walk. Or would it be the same because I'm burning the same amount of energy.
