Water has a thermal conductivity 25 times and a volume-specific heat capacity over 3000 times that of air; subsequently, surface cooling is precipitous. The primary components of the cold shock reflex include gasping, tachypnea, reduced breath-holding time, and peripheral vasoconstriction, the latter effect highlighting the presumed physiologic ...
Freezing cold injuries are diagnosed based on symptom presentation, but several weeks are often needed to determine the full extent of tissue injury. [6] In suspected severe cases, magnetic resonance angiography (MRA) or Technetium-99 bone scan may be used after injury to determine the likelihood of tissue recovery and potential need for ...

A smaller, similar reaction occurs when you try to put out a kitchen grease fire with water. The water hits the hot grease and quickly expands into a huge flame -- i.e., not what you were going for.
A water temperature of 10 °C (50 °F) can lead to death in as little as one hour, and water temperatures near freezing can cause death in as little as 15 minutes. [37] During the sinking of the Titanic, most people who entered the −2 °C (28 °F) water died in 15–30 minutes. [38]
