The hunting reaction or hunting response is a process of alternating vasoconstriction and vasodilation in extremities exposed to cold. The term Lewis reaction is used too, named after Thomas Lewis, who first described the effect in 1930. [1] Vasoconstriction occurs first to reduce heat loss, but also results in strong cooling of the extremities.
Most often, frostbite occurs in the hands and feet. [7] [8] The initial symptoms are typically a feeling of cold and tingling or numbing.

[3] However, frostbite differs from acrocyanosis because pain (via thermal nociceptors ) often accompanies the former condition, while the latter is very rarely associated with ...
The condition can cause localized pain, discoloration (paleness), and sensations of cold and/or numbness.

Cold injury (or cold weather injury) is damage to the body from cold exposure, including hypothermia and several skin injuries. [6] Cold-related skin injuries are categorized into freezing and nonfreezing cold injuries. [5] Freezing cold injuries involve tissue damage when exposed to temperatures below freezing (less than 0 degrees Celsius).
