Cold stress is caused by cold exposure and it can lead to hypothermia and frostbite if not treated. Mild Symptoms of mild hypothermia may be vague, [ 15 ] with sympathetic nervous system excitation (shivering, high blood pressure , fast heart rate , fast respiratory rate , and contraction of blood vessels ).
Hypothermia and extreme stress can both precipitate fatal tachyarrhythmias. A more modern view suggests that an autonomic conflict — sympathetic (due to stress) and parasympathetic (due to the diving reflex) coactivation — may be responsible for some cold water immersion deaths.
Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate. Hypothermia can set in when the core temperature drops to 35 °C (95 °F). [2] Hyperthermia can set in when the core body temperature rises above 37.5–38.3 °C (99.5–100.9 °F).

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).
“Wind chills across much of the Dakotas and Minnesota will be below -15 degrees with some portions of North Dakota as cold as -30 to -40 degrees. This poses an increased risk of hypothermia and ...
