1) Why is it a greater benefit to have the whole body be warm as opposed to just the hands? 2) Why does warm body temperature increase blood flow? 3) Why does increased blood flow enable faster hand movements? If you have answer(s), please feel free to use as much biological terminology as you'd like. This is mostly for curiosity but I may end up using this information in a schoolwork-related presentation.   | ||

1) Why is it a greater benefit to have the whole body be warm as opposed to just the hands? I'm not certain on it, but I believe the warmer your body temperature around your vital organs, the warmer your extremities overall will be. Blood-flow is constricted in your limbs to protect your vital organs when you get cold, so making your overall body temperature warmer allows blood to flow more freely to your hands/feet. Thing is, I'm not sure where I know that from, so I could be completely wrong. :p | ||

Also, muscle contraction may occur faster as well and sensory information would be processed faster. These are my hypotheses anyway. | ||

You know that being warm longterm lowers your reaction time instead since the body tries to not get hotter and thus tries to shut down as many things as possible. | ||

The temperature in your body is kept even through blood circulation. Because the blood contains the warmth, when it gets cold outside, your body attempts to minimize the blood's surface exposure to the external environment by narrowing blood vessels that are near the outside of the body (like just under the skin or in the limbs). Keeping most of the blood volume near the center of the body (where it's already warm) prevents it from cooling too fast. The decreased efficiency comes from the fact that the muscle cells in your hands receive oxygen and nutrients at a slower rate. It's the same thing as when you try to cool down food like pasta or rice by stirring it - you're maximizing the pasta/rice's exposure to the cold external environment and allowing heat to dissipate faster. | ||
