What is the biggest problem a victim faces in any cold-water incident?

• A. Drowning
• B. Hypothermia
• C. Hypoxia
• D. Frostbite

Answer: (B)

Hypothermia is the main threat in a cold-water situation because water rapidly strips heat from the body—significantly faster than air. As core temperature falls, thinking becomes fuzzy, movements slow, and the person loses the ability to self-rescue or stay afloat. This systemic cooling progresses toward unconsciousness and potentially life-threatening heart rhythm problems, which is why hypothermia drives the outcome in most cold-water incidents. Drowning is a real risk if the person can’t keep their head up or remains submerged, and hypoxia can occur, but these are downstream effects of the body's failing to maintain temperature. Frostbite is a concern for exposed skin, not the immediate life threat in the majority of cold-water events.
