    Oh.... we must ask ourselfs... why do our feet become SO FREEZING COLD at times? We have gravity acting on us at all times.... yet blood flo is limted to our feet when we are literaly naked....

    Do our socks constrict blood flo....? No...
    Is the blood redirectings itself to vital organs... Possibly... But No....
    There is less motion in the foots extrematies.... yet they are still feeling the force of gravity......

    We sometimes walk on our feet all day... with socks and shoes on they feel nice and warm..... but try to walk around all day without shoes and socks.... why in gods name are these extrematies are cold to the touch......

    and too boot, the take so long to warm up, no matter what you attempt.....


    Is their some odd science to the lower extreamaties I do not know, or am I clearly loosing my mind?

    They say most heat from the body is lost from the HEAD, and Secondly the Torso.... why do my hands (even when Inactive, still warmer than my feet, when logicaly the blood flo should be at the max consdier the laws of gravity.......


    You can have ice cold feet... but out them in a sock and a shoe... they become the warmest part of your body it seems like....


    Is there some science behind this? What is going on?

    Yes, you've already guessed much of the correct answer. The body is directing more bloodflow to the internal organs. It conserves heat as apart of it's self-protection scheme.

    It will not reduce the flow to the brain and the flow to your feet is not cut off, just reduced and sometimes severely so. Your hands are considered more important than your feet, therefore the first reduction is in the lower extremities and the upper ones - hands and arms will follow next.

    Your feet are also a bit more flat. They have more surface area for the volume they occupy (versus your head or torso) so it's easier for the blood to acquire the temperature around them.

    might have something to do with all the impact they have to sustain as well.too much blood in them would probably cause problems.anyone tried the thing where you cut off blood to your hand and hold it below your waist for a few minutes then fling it forward like you're throwing something?

    Your feet are touching the ground. The only part of your body that loses heat by CONDUCTION.

    The feet are the farthest part of our body from our torso and the farthest part of our body that our heart pumps blood too. Not only that, but like our fingers, our feet have five small toes that must be warmed by this extremely far away blood source. By the time it circulates down to your toes, its the coldest extremity. That's why toes are the first part of the body subject to frostbite: second to the fingers. They're very small compared to our other body parts and dissipate heat faster.
