Immersion, << ih MUR zhuhn, >> foot, also known as trench foot, is a diseased condition of the lower limbs and feet that is caused by prolonged exposure to wet cold. The symptoms of immersion foot resemble those of mild to moderate frostbite. Soldiers, outdoor workers, and hunters often suffer immersion foot. The condition is treated like frostbite–by cleanliness, rest, measures to restore circulation to affected areas of the body, and treatment of any underlying infection. Deep tissue damage is unusual.
