The Institute for Sports Sciences of the Innsbruck University conducted a study to evaluate the effects of coldness on the human body.

If the exterior temperatures are extremely low, the temperature of the extremities decreases significantly. This is due to the fact that the body automatically withdraws the blood from the periphery when the temperature decreases, to maintain the body temperature.

As a result, we feel cold first on our fingers and toes. This feeling is exacerbated due to the fact that we have 13 cold and only 2 heat receptors on a 1 cm² piece of skin. In fact, the body senses cold as the greater danger than heat.
