Trench foot occurs due to prolonged exposure of the feet to cold, damp, and often unsanitary conditions. [1] Unlike frostbite, trench foot usually occurs at temperatures above freezing, [1] and can be classed as a form of non-freezing cold injury. [3] Onset can be as rapid as 10 hours. [1] Risk factors include overly tight boots and not moving. [4]
Non-freezing cold injuries (NFCI) is a class of tissue damage caused by sustained exposure to low temperature without actual freezing. [1] There are several forms of NFCI, and the common names may refer to the circumstances in which they commonly occur or were first described, such as trench foot, which was named after its association with trench warfare.
Hyperhidrosis is a medical condition in which a person exhibits excessive sweating, [1] [2] more than is required for the regulation of body temperature. [3] Although it is primarily a physical burden, hyperhidrosis can deteriorate the quality of life of the people who are affected from a psychological, emotional, and social perspective. [4]

Researchers have found evidence of frostbite in humans dating back 5,000 years, in an Andean mummy. Napoleon's Army was the first documented instance of mass cold injury in the early 1800s. [7] According to Zafren, nearly 1 million combatants fell victim to frostbite in the First and Second World Wars, and the Korean War. [11]
“With cold exposure, the body is trying to pull blood towards the core and it wants to supply blood to the core organ systems, like the heart and the lungs, so the extremities suffer in the ...
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 ...
