Which factor cannot be controlled by the individual but affects cold-water survival?

• A. Protective Clothing
• B. All of the above
• C. Water Temperature
• D. Length Of Exposure

Answer: (C)

In cold-water survival, the factor you cannot control is the water temperature—the environment sets it, not you. Water temperature directly influences how quickly your body loses heat, so colder water shortens the time you have before hypothermia becomes life-threatening, regardless of what you do. You can influence protective clothing by choosing insulating, buoyant gear that reduces heat loss, and you can control length of exposure by staying out of the water or limiting time spent in it. Because there is at least one factor you can influence, the uncontrollable factor is the water temperature.
