Immersion Foot Syndromes
Immersion foot syndromes are a class of foot injury caused by water absorption in the outer layer of skin. There are different subclass names for this condition based on the temperature of the water to which the foot is exposed. These include trench foot, tropical immersion foot, and warm water immersion foot. In one 3-day military study, it was found that submersion in water allowing for a higher skin temperature resulted in worse skin maceration and pain. Causes Trench foot ''Trench foot '' is a medical condition caused by prolonged exposure of the feet to damp, unsanitary, and cold conditions. The use of the word ''trench'' in the name of this condition is a reference to trench warfare, mainly associated with World War I.

Trench foot occurs due to prolonged exposure of the feet to cold, damp, and often unsanitary conditions. Unlike frostbite, trench foot usually occurs at temperatures above freezing, and can be classed as a form of non-freezing cold injury. Onset can be as rapid as 10 hours. Risk factors include overly tight boots and not moving. The underlying mechanism is believed to involve constriction of blood vessels resulting in insufficient blood flow to the feet. Diagnosis is based on symptoms and examination. Prevention involves keeping the feet warm, dry, and clean. After the condition has occurred, pain medications may be required during the gradual rewarming process. Pain m ...
