What is 'cold water shock' initially characterized by?

  1. Water inhalation

  2. Immediate warmth

  3. A calming effect

  4. Dry skin

The correct answer is: Water inhalation

Cold water shock is the sudden physical response of the body when exposed to cold water, often characterized by an immediate gasp reflex. This is caused by the body's natural reaction to the sudden change in temperature and can lead to inhalation of water. The other options, such as immediate warmth, a calming effect, and dry skin, are not accurate as they do not accurately describe the initial response to cold water shock.
