Every morning(all year long, worse in the winter) the backs of my arms (elbows and tricep) are ice cold. They usually warm up after a little bit however it's one of the first areas on my body, outside of hands and feet, to get cold. It doesn't matter how many layers I'm wearing.
I'm a 30 year old male at 5'6" and roughly 125lbs, yes, very thin and hardly no meat on my arms.
Anything I should get checked out or is this just because I'm thin and no fat, little muscle to keep my arms warm?
