How come i don't feel heat as much as everyone else?

when it's like, 80 degrees, i feel chilly. when its warm to everyone else, i'm cold. i always wear big sweatshirts and pants in the springtime, but I don't get why other people are so shocked. I never get hot in the summer, even if it's like 100 degrees. I never burn my tongue on burning hot food, either. is there something wrong with me?
