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).
The pathological mechanism by which frostbite causes body tissue injury can be characterized by four stages: Prefreeze, freeze-thaw, vascular stasis, and the late ischemic stage. [16] Prefreeze phase: involves the cooling of tissues without ice crystal formation. [16] Freeze-thaw phase: ice-crystals form, resulting in cellular damage and death ...
In freeze sprays, a controlled amount of this cooling is useful. Uncontrolled cooling, however, can result in freeze burns to the skin. According to controlled laboratory experiments, the gas from a typical deodorant spray can reduce skin temperature by up to sixty degrees Celsius. [2] The form of injury is freezing of the skin, a type of ...
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.

Bågenholm woke up ten days after the accident, paralyzed from the neck down and subsequently spent two months recovering in an intensive care unit. Although she has made an almost full recovery from the incident, late in 2009 she was still having minor symptoms in hands and feet related to nerve injury .
Inside the freezer, air is circulated by means of one or more fans. In a typical design cold air from the freezer compartment is ducted to the fresh food compartment and circulated back into the freezer compartment. Air circulation helps sublimate any ice or frost that may form on frozen items in the freezer compartment. While defrosting, this ...
