why do womens feet and butt get cold at night?

blood circulation slows down when your body is at rest or sleeping

what a weird question. i never feel my butt's temperature when i sleep. before i sleep, i'm usually sat there doing hw (and browsing this site heh) so my butt's warm.

as for my feet they're cold most of the time coz i'm always barefoot but i like that feeling

is like that but you can make it hot

well maybe cause their fellow is hogging the covers

It hapens for men also and needs treatment, consult a family physician.

my feet get cold but my butt doesnt

My butt has never done that, but feet get cold because they are the furthest from the heart.
