Title: How come I can have cold feet and warm armpits?
Post by: Mariana on 15/02/2019 13:49:39

Molatelo asks:

During winter, my feet and my toes become icy cold even when my armpits are sweating. What may be causing such an imbalance?

Do you know the answer?

Toes are peripheral circulation, and in cold weather, your body reduces peripheral bloodflow to reduce heat loss.

Your armpits are closer to core organs like heart and lungs, and have a better blood supply. Although bloodflow may reduce slightly in cold weather, your armpits will still have a better blood supply than your toes.
