A medical emergency would ensue if the extremities experience prolonged periods of exposure to the cold, particularly in children and patients with poor general health. [3] However, frostbite differs from acrocyanosis because pain (via thermal nociceptors ) often accompanies the former condition, while the latter is very rarely associated with ...
“This condition commonly occurs in individuals between 15 to 30 years, in which the fingers, toes, ears, nose or even nipples become cold when an individual is stressed or exposed to cold air or ...

It was thought that the hunting reaction protected the fingers against cold injury and improved muscle function in the fingers. An experiment has shown cold acclimation minimizes the hunting reaction (reduced mean temperature of the digits and a prolonged time of cold exposure prior to initial vasodilation), thus putting the hand at a greater ...
