What does it mean when your body parts go cold when exercising?

Answer 1

Your body is diverting blood to your muscles, but you sweat everywhere. As the sweat evaporates, it cools you, but the effect is more noticeable where you are not burning calories.

Your stomach gets cold when you work out because you are burning calories/losing weight. The fats and carbohydrates get digested much quicker and the blood begins to rush to other organs at a faster rate. Fermetation then kicks in and replaces the oxygen being lost from your blood going elsewhere in your body with lactic acid. The lactic acid will cause both a burning in you abdominals along with a colder feeling on the surface of you stomach.

Answer 2

No, that's a myth. The reason why your stomach is cold, is probably from just sweating in that area, which is why we sweat, to cool ourselves down.

--But it we're sweating it most likely means we're burning calories. Especially if you're moving in heat or exercising.

Answer 3

You do not have enough blood to feed all tissues in your body simultaneously. So, complex factors route your blood to where it is needed most. Obviously, during exercise your skeletal muscle needs a lot of oxygen and is generating a lot of metabolic wastes, like lactic acid. So, some arteries constrict and other dilate (vasoconstriction/vasodilation) in order to give your muscles what they need. So some areas have less blood to give warmth. But in general you body should feel hotter as more blood is released near the skin so that the heat will escape your body and keep your temperature close to average.

Answer 4

In general it just means that other parts of your body are more active and require more blood. thus blood circulation in certain areas might be low, resulting in a colder temperature. For instance: It's very common to have your stomach become cold while running because your legs require more blood because they are exerting the most energy.
